Description

I took this over 2 evenings with my Celestron C11 v4 HyperStar and 2600 mc (gain 100, -10C) camera.  M33 has a lot of HA in it, and so I wanted to try to capture the texture of the nebulae within the galaxy.  WBPP was used to calibrate, debayer, register, normalize, and integrate.  The drizzle master was processed in PI.  I did not use Star Exterminator here.  When I tried it, I got weird artifacts in the stars image, and after stretch and recombine of the starless and stars image, it did not look right.  So, I just did GHS on the image, and tweaked the processed image in Adobe Photoshop (Camera Raw Smart Filter).
