The other day I shared an image of NGC 6960 - the Witch's Broom. NGC 6992 is, of course, another prominent part of the Cygnus Loop formation - the remnant of an expanding shockwave bubble from a star that went supernova about 10,000 years ago.
This was taken on the evening of 7-24-20. Despite the fact that there were some early clouds, I set up both of my imaging rigs and was capturing photons for most of the evening. We did have some clouds roll through - causing the guider to loose the guide star - and creating a chain of events where Sequence Generator Pro shut things down, waited a bit and then later - when the clouds had moved off - started the sequence back up. I've had the automation finally working for me for the past month now and it's starting to pay off.
The framing on this one is a little tight for my focal length - but I think I got most of it in ok. I planned this out the day before using the mosaic tool in Sequence Generator Pro to lay out the precise framing. When I executed the sequence last night, the rig slewed to the object, plate solved to confirm location and current angle and then using my Flacon rotator, spun the camera to frame it just so…. Again - the automation is paying off.
