FYI, I had a C11 EdgeHD with a V4 HyperStar and it has an image circle of 35 mm and worked with my full frame ZWO ASI6200MC sensor. I now have a C14 EdgeHD with a V4 HyperStar and the same sensor and it works great! Another note that Starizona just moved last month to a new larger location about 2 miles from my house. Dean, Steve, and Scott are all doing great now that they have much more space in their new building.

[@lukomatico]

That's wonderful to hear!! Thank you so much for taking the time to share this information my friend, I'll likely buy an m54 adapter and try with my full frame cam at some point! :-)

[@RandallKayfes]

First, congratulations on your HS purchase and highlighting your journey with it. When I bought mine I took my C9.25 into Starizona and had Dean (owner) culminate my corrector plate. From the factory we found the corrector plate loose and not centered. Dean got the corrector plate centered and tightened down. Now it was time to culminate my HS. So like you we bottomed out the push pull knobs. Well guess what with the corrector plate perfect putting the HS flat made for perfect culmination. If only everybody lived within travel distance to Starizona. BTW Dean did not charge me a dime to get the corrector plate perfect as well as the HS culmination! So in summary I would say if you can make sure your corrector plate is perfect the HS becomes infinitely easier to utilize. You might want to check that piece out and see it make a difference with your culmination and other corner aberrations. Dean, Scott, Steve and everyone at Starizona - I cannot thank you enough for make AP such a pleasure!!!! BTW I never seen anyone mention the Starizona endcap for the camera end of the HS works great for covering focuser side of the scope. No light leaks - made of metal and great storage so you don't loose it.

[@lukomatico]

Thanks so much mate!! Luckily I already did center my corrector plate so that will have made things easier for sure! :-) I really like the tip about the end cap by the way, nice one!!

[@Astrolavista]

I really appreciate this video, Luke, and I’ll tell you why! I’m often asked about the best all-in-one telescope for capturing great planetary images while also being suitable for deep-sky photography. Of course, the answer depends on the budget. For those with tighter budgets, I usually recommend something like a 200PDS paired with a Barlow for planetary imaging. However, for those with a higher budget, my go-to suggestion is a Celestron SCT with HyperStar. The challenge is that many people shy away from this setup due to concerns about how difficult HyperStar might be to use. I’ve often linked Cuiv’s videos to reassure them, but now I have another fantastic resource to point them towards, so thank you! Keep up the great work. P.S. I hope you’re all doing well, and that Felix is settling in nicely!

[@lukomatico]

That's superb to hear Chris mate!! The hyperstar has been a breath of fresh air for sure, it's made my favourite scope even more versatile - love it! :-D Felix is doing great mate thank you!

[@RobertKarlBerta]

I have a long history (I am nearly 7 years old) with Hyperstats and its predecessor, the Fastar. My first version was on a 8" SCT Celestron with their Fastar setup and a mono ST237 which had a motorized filter wheel that was small so worked fine on the 8" aperture. Those chips were small but with the Fastar allowed a decent FOV at a good price considering the coast of CCD cameras those days. Celestron decided to drop that format but Dean Koenig of Starizona was able to take over the idea and improved it greatly with the Hyperstars. They went through versions allowing it to cover larger chip sizes, better images, and nicer features like beiong able to be easily colimated and internal filter drawer. Over the years I moved up size wise through each version. I had these on my 11" SCTs (have two of them... one on a folk mount and the other one on of the AP mounts). More recently I bought a 8" HD celestron and its match V4 Hperstar which gives amazng results. The 11" scopes are used on a couple of AP mounts... a 1100 and an older 900. The main reason for the 8" Hyperstar was for mounting on a ZWO AM5 for portable fast setup. I use an external guide scope and all ZWO gear with that one. My main imaging telescope is both a 6" APO refractor with full frame mono/filters for RGB Ha OIII SII and the 8" Hyperstar setup or a small 80mm APO refractor. The one scope I now recommend to others is te 8" SCT because it can be used at f10, f8, or f 1.9 with Hyperwstart. This makes a very versatile and easy to transport AND setup system for high magnication, regular magnifcation with around a 1 degree FOV , or wide field around 3 degrees FOV. I still use the 11" SCTs but less than the other gear for imaging. I also manage an observatory for Scouts and we have a 14" HD SCT also with Hyperstar but normally that is used visually. Some ask me about collimating Hyperstar. Franklyi it is very easy and they hold colimation quite well.

[@lukomatico]

Thanks so much for sharing that detailed write-up!! - I'd love to look through a 14" sct one day :-D

[@Miguel_Noppe]

I bought a RASA11 about a year ago and yes, it requires some work to adjust it to top performance/ But I did get a whole Baader UFC setup to replace the standard Celestron camera adaptor. The Baader UFC tilter was very helpful to get rid of my tilt. In the beginnen I also used a 3d printed arc for cable management, but I did not like the abbarations produced by it so I moved to a 4 vaned mask. Yes I have spikes on brighter stars now but I like them better then what was produced with the arc. Anyway, enjoy and CS.

[@CDigata]

Glad you went with the hyperstar, your going to have some fun.. one day and i mean one day ill have the funds to replace my edge 8 for an edge 11 when I can find the funds... look forward to see you compare it to the Rasa 11.. think you have replaced the Monster with a Beast ;)

[@lukomatico]

Thanks Chris mate!! In the end I had a lovely time with your old RASA for sure, I wish I'd had the money to just keep everything and not feel bad when such a scope was 'out of action' for a bit, but it's not realistic haha Hoping the hyperstar continues to behave as it's been honestly so painless thus far! :-) Best wishes and clearest of skies to you my friend, as always!

[@KingLoopie1]

Looks like something to save for!

[@Arcteek]

Great video! I have a hyperstar V4 on my Edge 8 and my stars are not nearly as good as yours. I spent at least an hour centering the corrector plate and collimation is near perfect with my tri bahtinov mask. I'm not sure what to do more at this point. Fortunately BlurXT helps me still get quite perfect stars in post processing.

[@PhilPassmore]

Having won a C8 in an online raffle (Clover), I asked the significant other if I could buy a Hyperstar, and being allowed, have not looked back. A few times I have reconfigured back to native f10, but have ended up so frustrated by the darkness that I have switched back to Hyperstar double quick! Have never regretted the purchase.

[@lukomatico]

[@KevinRudd-w8s]

Pretty awesome Luke. I would really like an Edge HD and hyperstar set up but my credit card has already taken a battering this year upgrading my existing set ups so I better leave it for a while. That image of the Orion Nebula was pretty spectacular for just twenty minutes worth of data.

[@lukomatico]

Thank you mate!! And I hear that, astro is such an expensive thing to be involved in haha

[@JonnyBravo0311]

Back when I bought my 8" EdgeHD, I was very strongly considering picking up a Hyperstar as well. The biggest drawback was that I shoot mono. I would have to buy a completely new set of narrowband filters that are bandpass shifted to deal with the f/1.9 speed. That, and I'd have to adjust my data gathering workflow to a single filter per night, or figure out how to take flats on each filter swap. I then considered picking up a dedicated OSC and just using the scope for broadband targets. That option didn't really sit well with me, either. I like shooting emission targets, and I've never really liked the dual bandpass filter approach. Hindsight being twenty-twenty, I really wish I'd just gone the route of a HS and new pre-shifted filters. Instead, I ended up buying a SharpStar 15028HNT. Yup, I bought new filters, too. Though I did save some money picking up 36mm unmounted filters (instead of the 2" filters I would have needed with the HS) with a wider bandpass to accommodate the f/2.8 optics. Unfortunately, I've spent all my time doing nothing but trying to make that scope work to my satisfaction. I've had that scope for two years and have yet to produce an image from it. Every time I bring it out, I spend all my time under the stars making teeny-tiny adjustments to the tilt plate. It has been an exercise in futility to be honest. The sad thing is I've seen such fantastic images produced with it, so I _know_ it can be an exceptional instrument.

[@lukomatico]

Ah mate that sounds incredibly frustrating, is it worth cutting your losses and moving on from the scope if it's killing your enjoyment perhaps? Life is short!

[@wattswheelhouse]

I've been waiting with one of these in my cart for a while now.

@wattswheelhouse that's superb!! Congratulations mate, enjoy that hyperstar!! 💪

[@wattswheelhouse]

@@lukomatico it reduces the imaging scale enough so that my poor, overloaded eq6-r can barely handle guiding the c11 precisely enough for it. Subs at 540mm of focal length look great! I'm definitely looking to upgrade my mount though. Care to do a mount tier list?

[@chrisschur6736]

Id like to suggest a method to reduce or alleviate the linear color abberations. If you do a star alignment in PI using thin splines on the RGB channels then merge - you will re register them and get far better images in the corners. Give it a try!

[@lukomatico]

Very interesting suggestion mate, thank you!! :-)

[@iamjessieray]

Very nice. I have thought about swapping my 130mm f/5 newt for a C6 and then getting a hyperstar later, but honestly the more I look at images taken with hyperstars the less I like the star shapes when I'm looking at something closely, which is quickly becoming one of my favorite things to do. For that reason I think I am going to just get a nice coma corrector to fix my stars at the edges and then buy a larger newt later, mostly so that I can easily find upgrade parts since almost nobody makes upgrades for the 130mm newts. All that to say that I think for me a slower system (by comparison anyway) with tighter and cleaner stars is more pleasing to me, but I can see how getting sick images in only a couple of hours is appealing. On that note, have you tried out any coma correctors/reducers? I know Cuiv has but was curious to know what your thoughts on those are if you have any. EDIT: I stand corrected. Backyard Universe now makes parts for the 130p-ds. These were not available last time I looked.

[@KJRitch]

I have a non HD C8. I guess there is no advantage of the HD when using a Hyperstar compared to the C8? If you set up and tear down each session and have to install and remove the Hyperstar I guess you will need to check the collimating every time? I wonder how far off it would be from a collimated previous session? I’ll be visiting Starizona’s new location near Tucson in March. I should leave my wallet behind. Thank you.

[@JoeGarrity-m1y]

Happy to see you have the HyperStar, Luke. I have the v4 for my EdgeHD 8". I'll be interested in your future videos related to your experience with the HyperStar. How much of a difference in exposure/integration time would you say f1.9 is to f3.9? I am considering a widefield refractor that's f3.9.

[@lukomatico]

Thanks my friend!! - I'd say f1.9 feels a few times faster than f4 (my newt) does in terms of SNR, but it's hard to say accurately yet without any side-by-side comparisons 👍👍

[@JoeGarrity-m1y]

Thanks. I got that impression from one of the other videos you recently published, where you figured that an F2 could capture four times the signal than an F7. I was guessing that f1.9/f3.9 might be 2.5 times "faster."

[@danbartlett7923]

Luke, I noticed in the video that you collimated the star and it looked perfect. But the star wasn't centered on the sensor. Any thoughts on what effect the lack of collimation when the star isn't centered might have on the average FWHM across the field of your images? Do take a look at your extreme off-axes unfocused stars with your HyperStar setup - it might be shocking . Thanks for educating us! Dan

[@lukomatico]

Thanks Dan! :-) good question! As I was using a very small region of interest to perform collimation it ensured that as long as the star was reasonably centered in the ROI, it was forced to ve very close to perfectly on-axis 👍👍 Hope that helps!

[@seemantadutta]

I love my Hyperstar v4 on my edge HD 8! But it surely needs readjustment and collimation.

[@Darren_71]

You sold the RASA 11 😮😢 My favourite scope ever, I sold my HD11 (to you) & kept the RASA. I did toy with getting a Hyperstar before the RASA. The only thing they puts me off the RASA Is the sheer size & weight, I leave my RASA attached permanently.

[@lukomatico]

Hey Darren!! It's great to hear from you mate, I hope you are doing well! :-) If I had a third pier and suitable mount I'd probably have kept the RASA, but as you saw it's pretty tight in the obsy haha! Hope you're getting plenty of clear skies mate, it's good to see you on the channel! 👍👍

@lukomatico clear skies are rare here 😂, but that RASA gets used well when they do 👍 Got rid of my much loved S50 & made a second little setup, a nice little Askar FMA180 on a SA-GTi, it's nice having a little lightweight setup to plop outside when you're too tired for the big rig. You soon get fed up of smart telescopes limitations of field rotation & 10s exposures. I'll buy another when they all do EQ mode (I may get a Dwarf3?) Congratulations again on the Baby 👶 👏 Clear Skies.

Ok so some bits will need bolting on so to speak but very impressive bit of kit mate. I love the RASA I really do but Celestron do supply some pretty crappy parts to use with the camera I must say as for what they cost to buy. I were using the M48 adapter on mine & the vignetting with an APSC camera was pretty bad I'm sure they could do better. As for rotating the camera yeah I hear ya as its a right faff although I did get a rotator from Ali Express which made things a lot easier.

Could you use something like a Canon R5 with these? Is there a downside to having a larger camera at the front of the scope i.e. from a light gathering perspective or does this not really make much of a difference in reality?

[@lukomatico]

@@davefellows hey mate! It won't cut down on your light gathering noticeably, but the squared edges and straight lines on the camera will introduce diffraction effects (spikes on brighter stars etc) I don't know if the R5 is FF, but it's worth noting that I don't think field coverage would be excellent over FF, but it's wonderful over APS/C at least :-) Hope that helps!

Thank you mate!! Re: focus settings, I'd probably change to trends and parabolic (rather than hyperbolic) - set your base focus exposure time to be 5 seconds or so, focuser settle time to 2 sec, bin2 mode, focus step size to 100 and have a counterclockwise (make a movement and double check which is which before setting) focuser backlash of around 1500 steps if using an eaf Hope that helps!
