Rosette in the cold


Recommended Posts


I wasted at least one night chasing down some power problems, and another totally failing to add a focal reducer into one of my setups.

Problems aside I was able grab 15½ hours on The Rosette Nebula in narrowband.


Pretty happy with this one (and it's rare I say that after a first attempt at processing) but I'm still happy if anyone can offer tips, advice or constructive critcism.

That's nice! I had a go at this with a dual passband filter and 533mc, but could only dedicate one evening to it, and that was blighted by intermittent cloud and poor seeing. 15 hours plus is great. It makes a difference!
