M42 - Over the last three years

I thought it might be interesting to look back at my attempts at M42 over the last three years and compare the results.

All taken with the same 450d

Konus Vista 80s, NexStar SLT (AltAz)


C80ED, Unguidded


C80ED, Guided HEQ5


The reason my first attempt is so read, I used a Semi APO filter to help with the CA, and it removed a lot of blue.

Practice and improvements in kit and technique have really helped.
