Description

After getting all set up, the clouds rolled in at 10:00PM. I waited it out for an hour and then the clouds became intermittent. I managed to get a few hours worth of images, but it was also very hazy. The LP filter was crucial here, as well as the amazing capabilities of PixInsight. I also realized that I should put a LP filter (Optolong L-Pro) on my guiding camera. Wow, this made a huge difference. More stars and higher contrast for guiding!
