NGC 7331: by Greg Morgan 12.5" RCOS & STL-11K Lum 5.5 hours, notice all the blooming taking place. The ABG trim pot needs to be adjusted on this camera. |
This is a test image of a 30 minute sub-frame 1x1 Lum filter. The ABG or gain on the STL-11K is set to high. It needs to be adjusted down to a level where the blooming will not take place. |
This is a 30 minute sub-frame of a slightly brighter star. The ABG trim pot has been turned 1/4 turn CCW for greater ABG protection as described here. |
