Description

I imaged IC-417 with my CDK14 back in December. This is a couple of nights HSO.

I have a couple of problems with my larger setup. There is an internal reflection that shows up with brighter stars in the field. It is only a problem with my Chroma Oiii filter. If you look closely, you can see a "ghost" ring from the reflection near the bottom center. On some images, I have had these repeat multiple times in rows. This also causes blue halos (when Oiii is in blue) around the brightest stars. I have already tried flipping the Oiii filter over. Next, I will darken edges.

There is also some horizontal "walking noise" that affected this image. This seems to become a bigger problem with my ASI6200mm running at 75%+ power but I have had this noise show up even at low power. I replaced my USB3 cable. That seems to have helped but not completely. I am starting to wonder if maybe the noise is coming from the input power supply.

I used a combination of EZ SoftStretch followed by GHS for stretching. I used GHS to brighten the image and stretch the fainter nebulosity.
