If it ever gets clear again here i am planning to piggy back my
DSLR on my LX200GPS and take some widefields with my vintage 200mm and 135mm lens'
In prep for that I thought I go back and see if my 2 years trying to learn processing would help me improve my previous images captured with those lens's.
So I worked from first principles on my M42 from Xmass 2019 . This was taken with an unmodded 1100d, A Takumar 200mm lens (circa 1970s). It was pre and post processed in
Pi with some final tweaks in
PS. It was less than 2 hours integration on a star-adventurer
This was my original from nearly 2 years ago done in
APP and
PS I was pretty pleased with it at the time.
I'm quite pleased with the improvement and really excited to see what those old lenses can do with proper guiding and my Modded 700D (If those come out OK I may even strap the lens onto my ASI2600mc and see how that goes - i have a few widefields in mind that I think the 2600 could do a special job on).
