Re: Brightness and White Balance Adjustments after Smart Histogram Brain

Hello Again! I just performed the Bias tests on a new ZWO ASI071MC Pro camera and found that it took a Brightess/Offset setting of 55 (max is 80) to center the data at only a Gain of 100. Moving to a Gain of 125 took required a Brightness of 70, and at a Gain of 150 I ran out of Brightness to center...

Re: Pixel Streaks - What's Causing Them?

Ok, thanks. Still, I'm going to change my settings so that my darks are saved as .png files again and see if the issue goes away.

Re: Pixel Streaks - What's Causing Them?

Hi Robin, The darks were taken at a different time than the lights, but in both cases the camera was being cooled to -10C. The file name for the darks indicates a temperature of -9.4C and the file containing the capture info for the lights indicates -10C, so very little difference. What about the .f...

Polar Alignment - Camera Orientation?

I've just implemented a Guide Scope to my imaging setup but the mount arm for it is NOT directly on top of the scope, but rather about 15 degrees to the right of vertical. To use the SharpCap Polar Alignment tool, how should the camera sensor be oriented into the guide scope? Should the camera senso...

Re: Live Stack with Flat Frame Bug?

Thanks BlackWikkett, more great info!

- After you've finished capturing all of your frames, which "Save" option are you using, and what format (FITS, etc) are your saved files?
- What is your method for doing the White Balance in Photoshop?

Re: Does "Flip" Matter for Dark Frames?

Thanks Robin and Dave. I tried to do a meridian flip while live stacking a few nights ago and failed but for a different reason. I did a "Save as 16 bit stack" and then paused the live stacking, moved the mount to the other side, and then changed the gain to maximum and shortened the exposure to abo...
