| Notes: |
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. NGC 5490 is the Elliptical galaxy to the south |
