IC 1396 from last night with only a histo stretch applied. This shot could have been better, however half of the shots were overexposed.

I used the auto white balance in BYEOS. My cam is a Full Spectrum modification.

IC 5070 aka the Pelican, shot Thursday morning. This was shot with no cooling, so the sensor had a temp of 88 degrees. Cooling is now fixed so noise should not be an issue.

C11 the Bubble Nebula shot on Thursday. I am still trying to figure out what is causing the noise in my images. I lowered the exposure time thinking that it had something to do with it, but no luck.

Not a problem! Glad to help out. I was supposed to be on a hangout, but it got canceled. So you just happen to catch me with nothing better to do :)

Finally got the scope out, and decided to give M31 a try. I had numerous problems on this night, and this is only 10 light frames as a result. The DSLR lens fogged up, the focuser started slipping etc, etc,.. This is just a quick processing with only a histo stretch applied.

The histogram should be at least 1/3, but no higher to properly set the exposure time. Thanks for the comments :)
