Re: HOWTO Debayer Captured Images
Thanks for posting this Kirk. The files were captured in SharpCap v3.1.5219.0 Kirk - do you have the Sharpcap capture settings file to post? Did the files you put into PIPP come straight from Sharpcap or via some other software? Robin - any thoughts on the "TIFF file has unsupported compression...

Re: IC 5070 Pelican Nebula
Minos At home, the Celestron AVX mount is sat on a fixed pier (bolted to a 2' x 2' x3' deep block of concrete). When at my dark site, I use the AVX tripod. [Note: for clarification to others reading this post, All Star Polar Align (ASPA) is a facility built into the Celestron mount firmware to enabl...

Re: To Gain or not to overGain
This thread gets more interesting by the hour. When I took up Astro-imaging as a hobby a couple of years ago, I aspired (and still do) to create the images like those at http://www.orionoptics.co.uk/imagegallery.html . I will leave it for anyone interested to look up the specs of the cameras used. ;...

Re: IC 5070 Pelican Nebula
Cheers Brian. A tricky one to dig out of the stack - some changes needed to capture settings.

Re: To Gain or not to overGain
Mitch In discussions with Nick @ Altair, he has been suggesting gain values of 2% - 4% which translates to gain=100 to gain=200 in SharpCap. These figures seemed to work well for my M31 and M52+NGC7635 in the Gallery. The black level=100 was to ensure no black clipping (decided by looking at the Min...

Re: To Gain or not to overGain
Mitch Back to your original post. How about this: choose some object capture using smart histogram suggested settings capture using a variety of exposure, gain, offset values (user defined) process captures ideally following the same process report back with images and findings I have not seen any s...

Re: To Gain or not to overGain

Open an image file From the menu, click PROCESS -> MATH -> MULTIPLY In the dialog box, enter the value 16 (optionally check Preview) From the menu, click FILE -> SAVE AS (choos...

Re: To Gain or not to overGain
"Save 10/12/14 bit images in FITS files without stretching to 16 bit (Altair, QHY, ZWO cameras only)" The default for this box is unchecked. Robin - perhaps a note on the screen or a tip to say something along the lines of "only enable for use with photometry" otherwise we will ...
