Meade etx127 mak vs W.O 126ED

[@janomacko5764]

With the huge amount of surrounding light, the Maksutov could have benefited from having dew shield. It not only prevents dewing, but also stops some unwanted light from environment and perhaps slightly increasing the contrast. I don’t expect it would make make a huge difference, though.

@@janomacko5764 very true on what you said sometimes these comparisons which could be helpful. Sometimes it depends on the seeing sometimes it could be on the object we’re looking at maybe different objects would have a different outcome. I can only go by what I saw that night and just tell you guys what I saw. Maybe in the future, I can do a update on different items if I still have both telescopes and we can see if there is the same outcome or a different outcome. Thanks for watching.

[@JoeJaguar]

@@janomacko5764 that’s true it could’ve benefitted from a shield, but I only borrowed this from a friend and it wasn’t my own personal one so I didn’t want to buy one or build one since I just borrowed it for short time I believe the owner has a shield for his telescope, but he listened to me without it

[@JoeJaguar]

@@janomacko5764 have you watched my couple videos that I’ve done of the 140 mm if not look for it about 3 to 4 months ago watch those videos and tell me what you think

[@janomacko5764]

@@JoeJaguar You can find my comments on kzbin.info/www/bejne/rmTPd5iBj7h4ptE and kzbin.info/www/bejne/lYPJmoiCjbSMeLs I don't have much to add. Large aperture and no false color halo on Moon + good mechanics is a dream. Even though you are using it from under street lights, you may try to point it at some bright open clusters while waiting for perfect cooling down for planets. Probably M36 or cluster inside Rosette nebula. My advice is using blanket over head, exit pupil around 3-4mm, and perhaps even extend the dewshield of the telescope to block street lamp lights more. It won't be as nice as from your travel destinations, but hey, why just sit inside while waiting for the telescope to cool down?

[@AVTAstro]

Awesome video Joe! Good to see that the Meade Mak held up well to the APO. I'm surprised that the Mak did not dew up. You must have a dryer climate then me here in the NW.

[@JoeJaguar]

@@AVTAstro if I go to the lake, which is about 3 km away definitely even with a dewcap I’ve seen it after 45 minutes get wet But away from the lake, I normally don’t have a problem and seeing conditions here are usually fairly good however light pollution sucks but that’s a different story Of course, this was only on Saturn Yesterday I tested too, where they looked almost equal on Saturn then when I went to Jupiter and pumped up the power, that’s when I noticed the difference so I wonder if the same thing would happen I possibly could do a second video if I can borrow that Mac again from my friend

[@laquerhead133]

Found your channel through AVT-Astro. Thanks for doing this for urban stargazers. I would love to see the achromat review. I am in a situation where I live in an apartment in a city and mobility is paramount. I have to lug things up a few flight of stairs to get to my rooftop, so "grab and go" means something quite different to me--it must fit in a backpack. I am eyeing a Skywatcher StarTravel 120 to be my primary scope, but I have never seen chromatic aberration outside a tiny 80mm Celestron TravelScope and hear only horror stories. The 80mm does not bother me much, but the bigger scope might make it worse. No idea! Would love to hear your thoughts about that rig.

[@JoeJaguar]

@@laquerhead133 I am just at a Christmas function right now so when I get home, I’m gonna give you more of a thorough explanation When people like yourself ask for something specific and detailed, I want to go into enough explanation so I will do that when I get home thank you for joining my channel My channel mostly is about comparisons and reviews and mainly to encourage, you can do astronomy even for my big city

[@JoeJaguar]

@@laquerhead133 you’re correct grab and go means a lot to different people First, I have done lots of reviews and comparisons of acros if you just look at my channel I think I agree that if you get a short tube 120 might not be the best and here’s the reason why . The chromatic aberration of the 80 mm F5 is not so bad but as you scale up to the 102 mm F5 the chromatic aberration doubles so if you go then again to a 120 mm F5 it again doubles The 120 mm F5 would be great for very wide field of views in the country skies however in the city where you’re probably mainly gonna be looking at the moon and planets, I don’t think it’ll be recommended Not only will there be a lot of false colour But that false colour Also degrades the image sharpness and contrast when looking at the planets, you want to see a clear sharp image with lots of contrast. I don’t know what your budget is but if you go to 120 mm F8 or F10 that would be a much better telescope in the city . It was still have some colour but not as bad as an F5. And will also be somewhat sharper and more contrast. The downfall is the tripod and mount that you will need for a 120f8 to f10 telescope is probably gonna be a CG4 or larger which will not be portable enough to go up and downstairs I have a few suggestions 1- svbony 102ed f7 . ED refractors correct for at least 70% of the colour correction and sharpness it comes with much better focuser than ones on a acro. It also has a sliding front shield so it folds down which will help you for portability It is also not too big and heavy look at my channel for this video in the description. I have a link, which gets you 10% off. You can mount us on the svbony 225az mount and with a tripod this will be a portable set up that you could probably carry up and down the stairs without much trouble 2 skywalker Heritage 150p. This is a reflecting telescope, but at 6 inches you can start to see a lot more than just the planets like open clusters. And being that it has a parabolic mirror, it’ll be nice and sharp. Their heritage folds down to about half the size so again this on the. Svbony az mount would work very well for the planets and deep sky object objects. I have done a video that’s called. Can you see deep sky objects with a 6 inch telescope? That was about 7 to 8 months ago take a look at it and see if you can find it. I also show that I use the buggy to go to the park, which is about a block away and it was easy with this telescope But also carrying it up the stairs should also be somewhat easy I am not sure I would recommend a short tube acro, Nor a long acro either. The good thing is if you take the heritage 6 inch once in a while or whenever you can to a dark side to the 6 inches will let you see some of the brighter galaxy and Messier are an objects like nebula and globular clusters The 102 ED could also show you some of these objects, but of course not as bright That’s my two recommendation if you want something that’s kind of portable not too big and heavy that could be carried upstairs or to a park I use the sky watch your heritage 6 inch when I go on an airplane travel and it suits me very fine. Either one could be good, but I would recommend the heritage for its extra aperture. Again look for these two telescopes on my channel and I’ve done at least a few different videos on them

[@laquerhead133]

@@JoeJaguar This is wonderful, thank you. I will certainly look out for your travel videos with the Heritage 6". That is super helpful. And I appreciate the thoughts on the shorter 120's; I will cross that off the list. Interesting re the 102ed and putting wheels under the Heritage. Much food for thought!

[@3dfxvoodoocards6]

I expected the WO APO to be significantly better...

[@JoeJaguar]

@@3dfxvoodoocards6 I know I thought of that too. Now it could’ve been that the scene wasn’t great or it was because this test was mainly on Saturn maybe if I would’ve had the time for Jupiter that could’ve been the difference as well but again it’s only one test. Maybe in the future, I can ask my friend to re-borrow again and try it again on Jupiter and maybe Venus and a couple other things

[@3dfxvoodoocards6]

@JoeJaguar most probably it was because the seeing wasnt great

[@JoeJaguar]

@ yeah I’m assuming that’s probably what happened. It was only on Saturn. I believe if I recall on that video if we did a second test and maybe on Jupiter or Venus, maybe and if the seeing was better than could be a different results. If I choose to redo it on a couple different objects in the future, if I can borrow it from my friend again, and if I don’t sell the William optics by then I may consider doing a update to this video

[@manolismavrelis5854]

that was a surprise ! i thought the apo would beat the mak . thanks for the shootout.

[@JoeJaguar]

@@manolismavrelis5854 it was kind of a surprise to me, but again, mainly it was only on Saturn and it could be the singing wasn’t good enough that night I suppose if I do a second test, we try it on Jupiter. I can ask my friend if I can borrow it again and see if we get the same results.

[@manolismavrelis5854]

@@JoeJaguar looking forward to it !

[@JoeJaguar]

@ thanks

[@spacecadet6575]

I thought it would be close. However, for it to be really fair, I think you have to subtract the 31% central obstruction from the ETX's aperture and compare it to an APO of that aperture. Possibly 102-115mm? Maybe that would be closer to an apples to apples comparison.

[@JoeJaguar]

i hear you but i can own every scope out there i try to do my best from what i have or if i can borrow. 99% of the time iam buying scopes to do these videos. iam not sure other buy as many scopes as i do but even then i cant get everything.

[@spacecadet6575]

@@JoeJaguar Hi Joe- I wasn't implying that you actually need to go out and buy 100 scopes. LOL But I think the brightness deficit that the ETX Mak had has to be due to the central obstruction. I think that until you get up to the elite brands of APO scopes like TAK and AP, etc., a well made Mak of the same aperture (adjusted for central obstruction), has the advantage. Now if you start including long focal length (f15+), research grade refractors, all bets are off. Great videos!

[@JoeJaguar]

@ well of course you’re right and some videos I do talk about if you minus the central obstruction and depending what type of reflectivity the mirror has maybe a more comparable situation might be like 115 mm to 120 mm refractor against 127 mm central obstruction telescope would be more accurate I believe maybe two years ago or maybe even 2 1/2 years ago I had a different ETX 127 and I compared it against my Takahashi 102 TSA and I found a Takahashi was much sharper in that instant This time I just chose to use a same size scope just to see what would happen Thanks for watching and your support

[@Vic-pz5oh]

If I didn't live 5 time zones away Joe I would let you try my skywatcher 127.chinese made.i don't find much difference between it and my c6

[@janomacko5764]

I have the same telescope. Great value for the money. Good on planets, and I often like to use it also on bright open cluseters due to its nicely flat field at f12. The double cluster barely fits into the field of view, but stars are pinpoint almost from edge to edge.

[@JoeJaguar]

i appreciate the offer thank you

[@anthonybending2687]

Would like to see the 140 askar v 150mac, that would be interesting

[@JoeJaguar]

@@anthonybending2687 unfortunately I don’t have 150 mm Mac. I don’t think I know anybody that has one either. I know someone who has a 7 inch Mac, but that might be too big. If I can get a hold of one in the future, I would definitely do it, but no guarantee I can find one, but thank you for the comment

[@lornaz1975]

You should try those two on the moon.

[@JoeJaguar]

@@lornaz1975 the owner of the Mac already took back his telescope. I probably could try to re-borrow it in the future but I also have the William optics for sale and I do have a couple people interested so I don’t know if I will have any more time to test them again? Since I got the askar 140 there’s no need to have a 5 1/2 and a 5 inch refractors If I can do it, I’ll try but no promises

[@lornaz1975]

@@JoeJaguar No problem. I have just found the moon to be a good object to check optics.

I'm new, hvnt brought one yet, narrowed it down to 140 askar or 150mak, going to set up with binoveiwers, thanks for the teply

[@JoeJaguar]

@@anthonybending2687 if you watch the channel, you’ll see that I purchased the askar 140 about four months ago. I did a couple videos on it a review on it and then one actually testing it. No question in my mind you should go for the 140 over the 150 Mac Unless portability is your number 1T but if not even as the first video watch it compressed it’s only about 29 inches
