Stacking Multiple Stacks?

Does stacking multiple stacks yield the same result as creating one stack of the total number of frames? For example, suppose that I create a live stack of 100 frames tonight and save as a 16-bit FITS file one evening, then create a live stack of 200 frames of the same image on another night. If I t...

Re: Plate solve questions

I'll piggy-back on this thread. I just tried to use the Plate Solving tool last night and kept getting the error: "Plate solve failed - only - 1 stars found. Maybe too few? Try reducing the 'sigma' value in the SharpCap settings....". It was initially set to a value of 50 and I tried lowering the va...

Astrotortilla Plate Solving Configuration - Can't find Solve-Field

I want to use the Plate Solving function of SharpCap and just successfully installed Astrotortilla for plate solving (into the default installation location) and it runs when invoked. My next step was to open SharpCap to configure it for plate solving. I opened the SharpCap Settings area and the "Pl...

Re: Dithering

Hi Robin,

Do you have an idea as to when the Dithering function will be modified to only consume the amount of time required to actually do the dither, rather than consuming the entire frame exposure time?

Thanks,

Mark

Re: Brightness and White Balance Adjustments after Smart Histogram Brain

Ok, thanks. I'll do some additional tests to see how much is being clipped on the left. Here's the big question. I did these bias tests for my ASI294MC Pro camera and the graph is below. As you can see, I needed very little Brightness at low gains and ran out of Brightness range at a gain around 450...

Re: Brightness and White Balance Adjustments after Smart Histogram Brain

Hi Robin,

Thanks for your response. Can you check my screenshots above and see if I did the Bias test properly? They show that at a gain of 200 and brightness of 80 (the max), I'm still clipped on the left side.
