NGC4088 and the Supernova

I decided to have a try at capturing the Supernova last night. So I setup the EQMOD goto features and it positioned the galaxy spot on in the middle of the sensor.

My first attempts at processing this had all sorts of oddities in the background

So I grabbed some darks, and added them into the mix, but that only made the image worse, and I didn't bother to save it.

I had a restack, threw out all the darks and bias frames, and most of the flats too... It looked much better, I wish there was some logic to all this....

After that, with power running low on all the components, the lock gone, thanks to the meridian flip, I gave up, packed up and came in. I'm very pleased with the second set of images.
