Description

The weather was not perfect at all. It was so windy I thought my grab & go solar setup will fall over so I decided to block the wind with my body by standing in a really weird position close to the OTA. Some data was bad but some was pretty good.

I don't think I can go any bigger with a grab & go setup personally. This OTA setup on top of the small (but surprisingly good when tuned) Skywatcher SolarQuest is still easily manageable and seems to suit the Finnish weather pretty good. Based on the results I think its time to stop tinkering with this setup and just start the imaging season. 

4.8 ms exposures, 60 seconds at around 160 fps, 125 gain in Firecapture. Best 5 % (480 frames) stacked.
