Re: Why Do My Captured OSC Frames Appear to Be Color Balanced?

Robin, I understand your explanation as to why it makes sense to color balance the color histograms in the master flat frame. However, in the case of my flats captured with my Ha filter, the green and blue histogram peaks are at a much lower intensity than the red peak. Doesn't aligning the green an...

Why Do My Captured OSC Frames Appear to Be Color Balanced?

Flat Capture.jpg I am attempting to do narrowband imaging with my OSC camera and I am seeing something that I find unusual when I capture flat frames in SharpCap. During the flat capture, the displayed histogram looks as I expect. The histogram peaks fall at the levels predicted by the camera's Bay...

Flat Capture With Darks

If I capture flat frames with the dark frame pre-processing enabled, does SharpCap actually subtract the master dark from the captured flat frames?

Can Live Stack Work With Short Exposures?

I have been trying to use the Live Stack feature to image Comet Neowise. I have been using exposure between 2-4 seconds. The SharpCap FWHM focusing aid works on the background stars but Live Stack will not stack images. At first I thought that the short frames were not giving the stacking algorithm ...

Re: Application of Darks and Flats in PreProcessing

Robin,

Thank you for the quick response. I have been using Live Stack to monitor progress and saving individual frames, hence I was confused when I read that paragraph.

Application of Darks and Flats in PreProcessing

I am a bit confused with this paragraph from the SharpCap Users Manual Applying flat frame correction will affect both the image shown on screen and the image data saved to any capture file, so there is no need to apply flat frame correction in later processing if you have used flat frame correction...
