Emisssion nebula, NGC7822, in Cepheus using ED80 Doublet, 600mm on HEQ5 mount.
Modified Canon 800D with Hutech IDAS LP2 Filter.
I used 27x 1.5 minutes @ 400ISO for this image. In terms of quality I'm not at all impressed I have strained the fabric of the image to get what I can out of it but I was pleased with the amount of HA that could be seen in not at all good conditions.
Stacked in DSS and processed in Pixinsight. I separated the stars and processed the gaseousness separately using 90% of the original image with 10% of the enhanced one.
