I have been eyeing the QHY268C as a great OSC upgrade from a modded DSLR but I ran across an alternative using the same chip on Aliexpress which sells for nigh on half the price:

https://www.aliexpre...earchweb201603_

 

With the current sale prices on, this is  reaaaaallllly tempting. Anyone have any experience with these cameras? The only hardware difference I see between this camera and the QHY 268C is that this is limited to M42, while the QHY can take full advantage of the M48 adapter on my quattro coma corrector.

although the same sensor. But the performance maybe have some difference. For example the QHY268C has the multiple read mode and it has the 75ke extend fullwell mode. So it is reasonable that the price has difference.

Thanks! I am not questioning that the QHY and ZWO offerings are worth the price difference. I am just seeing an opportunity and wondering what the associated risks might be and what I am actually giving up for this cheaper model. The multiple read modes and the 75ke extended fullwell on the QHY is definitely one difference I missed but I dont see that option on the ZWO ASI 2600.

Hard to believe that there's such a large price disparity.
Would guess a lower quality cooling system? Drivers?
Specifications seem a bit confusing between the various models.

Thanks for the test, I was hesitant to risk this amount of money.

If things go well, I may try to buy this one next year (I would prefer monochrome, though, despite the obscene cost of filters)

Its great to see you have had success with it. Are there compatability issues with mainstream acquisition software ?

Hi Gerard,

 

Do you owe this camera?

If so, can you post 300s and 600s dark please?

It's interesting that Rising Cam offers two options in the protect/filter window: IR cut and AR.  What option is the standard in ZWO or QHY 268C cameras?

I'd like to buy one of these Cameras, the only thing that puts me off is warranty and having to sending it back if something goes faulty.

The others use anti reflective glass. Using a permanent IR cut filter means less flexibility.

Same here. They are an unknown quantity, and I see the complex troubleshooting done by the ZWO and QHY cameras by other members.
I am not sure that Rising Tech is able to support these pricey tools.

I think the 2600 has a UV/IR Filter.

Mine comes tomorrow - earlier than expected. Just under a week. Fingers crossed! (Did the AR glass option)

Waiting the results and impression because i also want to buy this brand as i can't justify paying $2000+ for ZWO/QHY version.

My impressions will be delayed. UPS just acknowledged it will be late. Now saying Friday. I got suspicious when it still showed as in Alaska during the claimed delivery window...

I'm using RT571 since last November. You can check my results here: https://www.astrobin.com/users/S1mas/.
Cons.  Replaced fan - vibration was a cause of elongated stars. Sometimes gives random white shifted subs, like 1 from 50 or so. Very slow frame rate like 0,4 second using Sharpcap Ascom. No SDK for programs except native RisingSky. But main thing is HCG mode is like cutted down and begin with low FW - HCG at 100 begins with FW only 3788. QHY and ASI stats are much better here. I didn't found it somehow degrade my images tho. Tried to use it at LCG 251 at FW 20k with success ( look M31 astrobin ). Not much difference from HCG 100.

Overall I'm happy with camera and how it works at a price I recieved it.

We recently put a generic native driver framework for touptek-based cameras into NINA. This means that we can add support for branded touptek cameras provided the brand-specific SDK is made available. I've found out where to get this for RisingCam models, so if you want to test a native driver for this camera in NINA, I should be able to basically do a drop-in addition of support for it. Emphasis on should there ;)

Actually my plan is to use this with N.I.N.A. - I’d be happy to test if it ever leaves Alaska.

Simas, you've done some impressive work with that camera, despite some of the early challenges you experienced.  I was prepared to write that model off as problematic, but if the NINA team can get it to play nice, it will be hard to dismiss it so easily.

Two weeks ago i've tried it with NINA without a luck. It recognizes camera, but with no required options to manage. For example there were no option to choose HCG or LCG. It would be nice to make it work tho.

If you did it through the ASCOM driver, that would be expected since ASCOM doesn't have a way to make such controls available to the host application. If you did find it listed as a native driver camera, it was likely because the generic ToupTek SDK picked it up, but sometimes while that SDK will pick up a branded variant of a ToupTek camera, it will not have full control of it. Getting the per-brand SDK (the one for RisingCam in this case) in would address this.

Yes, he did, in fact i didn't expect it to be that good, and i feel it can be even better with more work and processing, it is just the camera design and driver is what making me or most to hold back, but i will keep watching because i am planning to buy an APS-C color camera, and this one is the most one in my mind due to its price, just i hope it won't give more issues i don't want/need to face.
