This has been a challenging field to image for me. This is the third season I have tried to capture the area around IC 983. The main culprit has been 0.16 magnitude star Arcturus, which is just 2 degrees NNE of IC 983. When I centered IC 983, I picked up a large fan shaped reflection from Arcturus, which I found impossible to process out. This year I compromised by placing the main object of interest slightly off center until I eliminated the reflection. IC 982 (1.3', mag 14.0p, Cl: SA0+) is the small round galaxy just below IC 983. NGC 5490 (2.4'x1.9', mag 13.1b, Cl: E) is the large Elliptical galaxy to the south.
