I was interested to see how the QHY10 would go with the GSO 10" RC scope and if there were to be any vignetting or difference in the flat field with a larger chip size. I only managed to get 4x5 min before the clouds rolled in on the 21st Dec and so the object was M42 as there are plenty of stars etc and I could compare the field with that of the 5" APO.
I must say that the image has no flats, darks bias etc and I'm quite pleased with the star roundness across the whole of the frame. No vignetting and a flat frame.
It looks like the QHY10 and the GSO 10" like each other and seems to do well from suburbia.
I had noticed previously with some of my images that one corner of an image would have slightly deformed stars which I eventually tracked down to that safety cut-in in the T to 2" adapter for the cameras. They just don't hold the camera in square without twisting it off centre. I got over this by ordering a new T to 2" adapter from Moonlight focusers that is just a straight, well machined 2" throat.
Fits the moonlight focuser perfectly without any off axis tilting.

Looks great Allan , I have taken a few images now with the QHY10 RC10
combo and like you no vignetting or any other artifacts . Using a IDAS -LPS filter i can easily do 15min subs with no light pollution or burnout from
a suburban backyard.
That is awesomely sharp. Mirrored though. Your best to date IMHO.
Thanks Marc - you know I never realised it was mirrored before. Doh!

Yeah BrisVegas looks wet for at least the next week or so and I just wanted to grab some photons when I was able.

Paul, longer subs will be the way to go as 15 min are possible from the backyard and Im sure with the greater well depth of the QHY10 will make for far better images than the QHY8. So far Ive been impressed with the QHY10 and 10" GSO RC
No reducer Trevor as this is the full frame from the QHY10. I have a CCD67 on order which will work with a little vignetting.

Marke, Thanks for the heads-up. I have an Idas _LPS and should try it sometime.
Gee whiz I am liking what I am seeing from these QHY10 cameras. That Sony chip is fabulous.
Great image. Such great resolution.
Greg.
Greg, Ive always been impressed by the Sony chips and had a QHY8 previously (which I regretted selling almost as soon as it was gone). Most of us dont bother with darks but for the purists you should use them. The chips seem very forgiving for suburban light pollution as Ive done 15 min from home with no really serious problems. I just had time to get some light to test the scope/camera configuration before the clouds rolled in. Better imaging will only bring out the potential for this combination and setup.
The pixel size seems to be a good match for both refractors as well as the GSO RC and I must say that Theo gave me absolutely top service as it was in my hands the next day after ordering.
The jpegs don't do justice to the tif files as when processed they are going from a 78Mb file to ~100Kb but the detail certainly is there to be seen. These 10 Mega pixel cameras seem to hit a sweet spot for me.
Fabulous for such a short amount of time Allan. I feel like the snail in a marathon with my 40D at the moment. I must admit I have been eyeballing the QHY for a while now.
Darrin, the Sony Super HAD CCD sensor ICX493AQA is really excellent and after spending quite a deal of time considering my options decided on the QHY10. The pixel size really hits a sweet spot for refractors as well as cardiotropics. QHY have fixed the situation with the sloppy cables and the DC201 with TEC controller works very well and stably. If you go down the QHY10 route you will not regret it.

I agree with everything you say Allan and I have been in love with mine since I got it 6 month's ago. I don't think we have seen the best from these cameras yet as more imagers get hold of them and start posting pictures I think we will see some great things.
Fabulous stuff Allan, I'm impressed with the cam/scope combo.
David, as Paul says below only when I get some serious imaging time will the best of these cameras shine through. The QHY8 has taken some stunning photos but the smaller pixel size and almost double the pixel count with high well depth will make this a great camera.

Paul, cant wait til you get your RC and QHY10 going and then we can get a serious competition going. Loved your shots with the 80mm and they showed really great images.

Thanks Allan, The QHY10 is a really good match for the ED80. Santa has bought me a few new toys for the RC10 and I am just waiting for the Bob's Knobs to arrive before I change the imaging train (don't want to do all the re-collimation twice!) I have an Orion Steadystar AO unit to add in and I have just got the TS Optics adjusting device for the GSO RC's focuser. http://www.teleskop-express.de/shop/...6--und-8-.html
This will allow me to eliminate the tilt that I have been fighting with (it's been making my pics a bit soft as the collimation was slightly out).
My hope is my RC10 pics in the new year will give the QHY10 a serious test.

Paul, Thanks for the Xmas message and the same to you. I hope that the mods work out. Ive been lucky as my collimation essentially shows no detectable tilt and Als collimation aid really helped me with the RC.

Rick, these scopes are really finicky for spot on collimation. Just hope you both sort it out and its interesting that the tilt aid is available. Be watching you with interest but Im beginning to really like this scope.
