Description

My stars wern't looking round/right so my friend Diego inspected & removed the secondary mirror assembly from my 10" Newt. Turned out it was way out of square and misaligned. (My fault for fiddling with it!)

Interesting too, in that it appeared to collimate ok, but this was misleading as results showed wonky stars.

It's now reassembled and this is the result, processed in APP using Drizzle - nice round stars corner to corner - Happy dance time

If the weather ever improves over Melbourne I'll redo the RGB stars and create a HaRGB image.

NGC 3572 is a star cluster situated near a molecular cloud in Carina about 6500 light year distance. These stars are young and massive and are only expected to live a few million years and explode as supernovae. These stars have shaped the clouds into amazingly convoluted shapes by their powerful radiation.(Eso)
