I saw the ASI2600MC duo at Neaf '23 and picked it up when it was available fall of last year. I first had it mated to a Mamiya 250mm lens and then an Askar FRA400. Both were mounted on a iOptron HEM15. With a regular camera tripod this was my traveling set up. I used it in NM for the Annular, and then in Texas for the Total. The Duo really minimizes the equipment you need to take, no need for a OAG or a piggyback guide scope, making it a great travel scope. The HEM15 is also super light weight. Guiding was nominal around 1.5 arcsec. I still need to wring out the cam/scope/mount combination. Since it was purchased as a travel scope for dark skies, I have not, and still not sure if I want to get a dual band filter, or any filters at all. I am with you on the camera ASIAIR combo. I guess if you are a ASIAIR fan it will push your buttons. Not me, I still prefer a laptop (running NINA). My rig at home is a full camera/guide scope/telescope with NB and LRGB filters. I am on Long Island in Bortle 6 skies. Thanks again for your reviews.

I've been using this with an EdgeHD 11, and it works like a champ. It works better with the 0.7x reducer, as the ASIAir starts to have issues solving at the native focal length. It *is* sometimes hard to find a decent guide star, but I tend to crank the gain or shift the FOV slightly (not by rotating). For the deeper scopes, you have use this or an OAG, as flexure makes mounted guide scopes unworkable. The duo also runs great on the 151phq on an AM5. I think the best parts are the easy setup and takedown, and ease when traveling.

Another nice video Cuiv! I've been using my duo on a (reduced f/5.7 456mm) FF80 for a year now. I guide an AM3 (at 0.6" accuracy) with 2 sec exposures through an Antlia Triband RGB filter. I've never had any trouble finding stars. The 220 sensor is a lot bigger than an OAG prism, and my filter isn't very demanding. Since it guides this good, I've never tried 1sec. At 16kg all-up, this rig pushes the envelope of the grab-and-go concept just a little bit (but I do keep it assembled and carry it to roof or balcony on my shoulder). Having one less cable and fewer "stickie-oot-bits" helps a lot with avoiding bumping into doorjams and lamps in transit and, if going on a car journey, the OTA can slip into soft luggage without dismantling and packing the individual accessories. It is a pure delight to use, and so convenient to set up on our private balcony using the ASIair mini's all sky PA feature. I have promised myself to go mono "one day", but I've promised myself full frame too, and a darksky holiday home 🤣. So the MM/duo/air might not be how this all plays out...

Most of my imaging was last summer & fall on various nebulae and a mix of 1 & 2 second guide exposures. It works great even through Antlia ALP-T dual band filters (HaOiii; HbSii). I would buy this set up all over again. I just bought the 2600 MM duo and tried it through Antlia LRGBSHO filters (SHO are 3nm; I can be evil as well). No issues with the LRGB, seemed sort of successful through Sii, less so through Ha, still unsure of Oiii. Need to review the images. 1 second no good through SHO. Only 1 night usage so far and imaged M101 2x5 min per filter. Not a good target, but the best I had and there was some haze and passing thin clouds. I may need a different guide cam for 3nm SHO.

Nice review Cuiv. I really can't afford one these cameras at the moment as I am currently saving for an SWG type mount. My concern regarding this camera was always about the effects of narrow band filters on the sensor, but you have answered that question. The version of the camera with the ASIair built in would come in very handy for the travelling astro photographer, especially if travelling to another country for a holiday as I am considering doing. You would only need the mount, scope, camera and psu and fewer cables to worry about too as no need for guide scopes, mini pcs etc. the down side is of course the loss of versatility and if one part fails thats probably it, the whole unit will be useless. That Newtonian looks nice, look forward to your review on that.

That's very interesting, and I feel something else is the issue. For all intents and purposes the LPro is a broadband filter, so there should be plenty of light reaching the guide sensor - so basically it should be the same as an OAG. Maybe the guide chip is simply too far off from the axis and an OAG Prism could be put closer (but that also would require a smaller sensor).

While the imaging sensor is excellent, the guide stars from my ZWO ASI2600 Duo with both a Celestron 9.25-inch EdgeHD at f/7 and a William Optics ZenithStar 73 are distorted and not round so the guiding is bad. I get much better results with separate a guide scope and guide camera. Plus, when using the JPEG share function on Asiair the resolution is downsized so it is actually less with the Duo than what I get with a smaller sensor ZWO ASI533MC-Pro camera.

The imaging circle of the scope is not big enough. If it is close to full-frame size, then there is no issue.

Interesting, and good to know! I never really had issues with misshapen stars for guiding as PHD2 seems very good at not caring about that. I'm really surprised/impressed you don't have flexure issues with the 9.25inch with an external guide scope btw! Guiding numbers aren't everything at that focal length with an external guider!

Thank you Cuiv for very nice video. I saw quite a few about this camera but finally I got answers for most of my questions. There is still one left, and probably very stupid. If the camera is rotated do I have to recalibrate the guiding? The same would apply for OAG, depending where I do the rotation. Or is the software somehow smart to include the rotation into the equations? This might be very important with upcoming electronic rotator. Thanks again!

I'd really like to see the 2600 MC Duo on a SCT like an 8" Edge HD. And Pegasus Astro has made an OAG with built in auto focus for a number of years now. It's called a SCOPS OAG and it works quite well. But having the guide camera on the same plane as the main sensor solves the focusing issue as they are both always at the same focus. That would allow me to remove the SCOPS OAG which is 31mm thick. It just barely works with my 8" Edge HD. ;0)
@sarahjanereilly93355 ай бұрын
I am hearing that it is not great with the 8 Edge HD and I am interested as I am looking at a new rig incorporating that scope. General wisdom seems to be to go OAG (possibly ZWO) with high quality guide cam - ASi174mm as a minimum, second choice is a trad guide scope. Would like to see more opinions and actual use experience on this though, as the duo would be cool.
@Colton_Acree5 ай бұрын
The duo works fine for me on the ehd8 without a reducer, but with the .7 reducer, the Imaging circle is reduced and so is the light that gets to the guide sensor. That makes using narrowband filters difficult. I've actually ordered an oag to use with the duo just for the edge 8. I beleive the ehd9.25 and up have larger imaging circles with their respective reducers.

I’m using it on an edge11 and can use a 12nm ha filter with now issues at all. Sometime finding guide stars can be challenging if I’m shooting galaxies, but I either rotate or nudge the mount around until I see one.
@CuivTheLazyGeek5 ай бұрын
Imaging circle and light falloff/vignetting come into play, although from what I hear, with the reducer it shouldn't be a problem. I wish ZWO have a 533 Duo or a 294 Duo with the guide sensor closer to the center!

I've used it on a Edge8 with reducer (~1400mm/F7). Only about half the guide cam gets stars. It actually worked fine on nebulae with lots of stars but less so for galaxies, especially with an Antlia quad band filter so I wouldn't;t trust it on anything more narrowband. Interestingly enough, in this setup AA+ seemed to work better than NINA/PHD2. PHD2 calibration gave a lot of errors. I have refractors too so I'll use it where it makes sense but for galaxies I'm just going to get an OAG (check out OGMA for good looking reasonable priced OAG set). In the end I think the price difference for the DUO is worth it for the convenience of a grab&go setup for refractors.

@Jcastleinfo5 ай бұрын
@@ctortolini CEM40, 3s on the Antlia Quadband. Only half the guide sensor getting stars is due to the small image circle of the Edge8 with reducer. Your RC8 may have a better image circle. Many people claim it performs "great" on the Edge8 but I don't think they were shooting many galaxies and not with a strain wave mount. I'm planning to upgrade to NYX101 this summer so the fast guiding requirements of strain wave also make me nervous and another good reason to just stick to an OAG.

Interesting review Quiv, though still have my doubts on how it would perform lets say with an f7 refractor and an L-Ultimate filter that is 3nm If it was cheaper I would try it myself Ow and about shooting true the same filter and refocussing with oag if not, I guess there are not many people using no filters at all, so changing filters won't do anything at focuspoint because most filters have an even thickness I suppose, so I never had to refocus my oag with a filter switch. Maybe with people who really luckily live in very dark areas but they should also use at least an uv-ir, what do you think about that ?

I have several misgivings that I've mentioned in another video, but mainly: - only two power ports - intensified single point of failure - what if someone wants to later buy a non-ZWO focuser, automated flat panel, or rotator which are not supported by the ASIAir? Or their mount has trouble with the ASIAir? They'll need to control that camera via something else, like a PC. Apparently it will be possible over Wifi (since it's official that it won't be possible over cabled connection), but I have my doubts about speed and reliability in that case (causing imaging overhead). Strategically it's brilliant, as it intensifies the ZWO lock-in.
