Description

With all this humidity, my dear old mount is having all sort of electrical problems, from suddenly resetting to getting stuck in RA randomly. I spent the last two nights fighting with this issues and I chose this target just to try if the stuck RA problem was happening at all altitudes.
Luckily I had not to move from my room to unstuck the mount, it was sufficient to re-slew on target by using stellarium but every time this was meaning: recenter the target, start guiding and hope this doesn't happen again. And tonight when my mount seemed to start behaving normally... clouds came in. :( ....I guess I need a break :P

So this is the Frustration Nebula in HaL-HaRGB, thanks for looking!
