Re: HyperStar C14 Suitable ZWO camera

That looks nice.
This weekend hopefully I'm going to try ASI174MC Cool with a Hyperstar C9.25".
Al, what spacing do you have there (between ASI and Hyperstar) ?

Re: ASI174MM Cooled focus issue

That is a problem if you want to use filter and a reducer with limited backfocus. There are these rotators but they add about 5mm to imaging train: http://www.teleskop-express.de/shop/product_info.php/language/en/info/p7356_TS-T2-360--rotator---only-5-5mm-back-focus.html http://www.teleskop-express....

Re: No image on screen

Just realized that if you are using video format (avi or ser) then you are limited to 1s or less exposure.
Change to image format (like tiff) and you can change exposure range to second range.

Re: No image on screen

How did you center it ? First eypiece then switch to camera ? If you have succeeded with planets I guess you realize they have different focus. Don't know what do you mean by exposure to 100% in Firecapture. My Capture have different set of exposure values. Anyway with even with brightest of DS obje...

Re: 1600MC-Cool and DSS

I think Green scale is not needed because you adjust other channels relative to green.
So you can get your colour balance right by just adjusting the other two.

Re: 1600MC-Cool and DSS

I've never bothered setting these with colour cameras as you can adjust balance later with Photoshop or what have you (or even DSS have some colour balancing settings which you can do after stacking).
Mind you DSS usually have done colour balance pretty good with default settings.

Re: ASI174MC Cool and software worries

Don't believe there's so much movement in 1 minute.
Have a reasonable decent mount (CEM60-EC).

ASI174MC Cool and software worries

I'm just starting a new season and upgraded many software (including Win10). Also upgraded newest software (ascom drivers) for ASI174MC Cool. Don't know if it's software related but it seems something is now different. Attached is image of M57 60 x 1s exposure. Strange vertical patterns. Which ascom...
