OK, I'm about to buy my first color camera for EAA outreach for my Celestron Edge HD 8 + Hyperstar 3.  The Hyperstar is new to me, which is why I'm looking for a color camera now.

 

I believe I've settled on the ZWO ASI183MC Pro, for both its pixel size (2.4um) @ my f/2 and high-resolution imaging (5496x3672).

 

Does anyone have any experience with the ASI183MC-P, either positive or negative, specifically for EAA (w/ Sharpcap)?

Does anyone have experience with my exact setup but with a different camera which they would highly recommend?

 

My intention is to LiveStack with short exposures to keep the audience engaged as details emerge and the background of the object is being discussed/explained.  Basically, I want to do for the rest of our night sky via EAA as what happens when someone first sees Saturn through an eyepiece.

 

I'd love to hear your opinion and/or any gotchas I need to lookout for in this setup.

 

Regards,

Ara

I have evaluated 8 ZWO cams in the last year with one notable exception (ZWO 1600) that I hope to evaluate later this month.  ZWO 224C, 290M, 183M, 183C, 278C, 278M, 294C, 385C with my CPC 9.25 @ F2, F6.3, F10 and F20... (eeekkk what was I thinking)....  

 

My findings to date for my set up:

 

ZWO 178 C best for Planets UV/IR Filter (nothing even close @ F6.3/F10/F20)

 

ZWO 178/183 Mono for Moon Ha Filter (nothing even close @ F6.3/F10/F20, 178 at F6.3/F10/F20 and 183 at F10/F20)

 

ZWO 294 C best DSO @ F2.2/F6.3 UV/IR, IDAS LPD2 and UHC Filters (still need to evaluate ZWO 1600 but 178/183C at F2 are very good)

 

Hope that helps... and any other Vendor Cams using the same Sony Sensors would be equivalent... Pat Utah smile.gif

It works great for me. The 183 pixel size is well suited for Hyperstar. In F-7 or F-10 configuration it is quite over sampled. I have not tried binning the camera in those configuration yet. I get good results regardless. I am using Sharpcap and have been happy with it.

Thanks Chris, great to hear!  I’m looking to use it primarily at f/2.

 

I have evaluated 8 ZWO cams in the last year with one notable exception (ZWO 1600) that I hope to evaluate later this month.  ZWO 224C, 290M, 183 M, 183 C, 278 C, 278 Mono, 294C, 385 C with my CPC 9.25 @ F2, F6.3, F10 and F20... (eeekkk what was I thinking)....

Thanks Pat, that is helpful.  When you say “294 C best DSO,” did you use the 294 @ f/2.2 with live stacking, or are you talking about “standard” AP sub lengths of 3-5mins+?  Did you not find it under-sampling at that focal ratio?

 

Thanks,

Ara

Ara, SharpCap on WIn 10 for stacking, others ASICAP for non stacking...I am using Alt/Az at 30 sec max exposure...Best images are arc sec/ pix less than 1 are excelent, but less than 2 are very good.  With Planets and Moon over sample is Best even 3X over sample (.25 arc sec/ pix) ...

 

I am using a 5K iMac for viewing and when using a 1080P Display you might not see the difference between 1 and 2 arc sec/ pix. Best Case is matching your cam/Focal reducer  with the resolution of your Telescope if possible... Pat Utah smile.gif

 

p.s. The 294 has such a tremendous advantage in Well Depth and Sensitivity, the Color Images have a better color depth and intensity that is not matched by the 178/183.  Certainly with some post processing or SharpCap adjustments when live viewing the difference can be narrowed to some degree... I am still evaluating the 178/183 color cams at F2 as the resolution is better, but the sensitivity is worse. For me the limiting factor is 30 sec exposure that can be overcome by using an Eq Mount or just stacking for a longer time...Pat Utah smile.gif

You stated Hyperstar 3 in the thread, but did you know version 4 has been released?

The difference is so small between the two versions it would not be detectable in the EAA world.  AP folks would most likely think it is a modest step in improving Hyperstar images.  I noticed the price has gone up by about 20%...so not to worry...Pat Utah :)

Chris, thanks, yes I had.  I just bought mine used (adapted for a different 8" SCT) and it's currently on its way to Dean @ Starizona to convert to my Edge HD with lighter housing!  The full price was always a bit too steep for me, and now more so with v4 :(

I can't comment on Camera, but you will love Hyperstar.

 

Like Pat Utah, I have a superior display device (mine a 4K UHD Samsung monitor) and I find that assists with camera <zoom>, which is desirable as although Hyperstar increases FOV x 5 (great!) that has a corresponding effect on reducing magnification.  It's not critical as a more common 1080p display is fine, albeit its 1,920 x 1,080 pixels is below the capability of your favoured camera. But if within budget, an upgrade to display is a worthy upgrade, but you also need a computer/graphics/connectivity that can handle it.

OK, I ended up getting an ASI294MC for the Hyperstar.  It arrives this week!  Thanks all for your advice!

 

Also, to my surprise, once Dean received the Hyperstar 3 I sent him, which I bought used, to convert to fit my EdgeHD 8, he said it was actually a Hyperstar 4!!!

Any updates? How's everything working out with your HS4 & 294MC? Just curious.
