An Old M42

#1

Post by Jockinireland »


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).
Scope: Skywatcher Evostar 80ED (SW 0.85 FR/FF) on a SW NEQ6Pro
Guiding; SW Evoguide 50ED, ASI 120mm mini

Sharpstar 61EDPH II (with dedicated 0.8 reducer) with wiliam Optics 32mm uniguide
Camera: ASI2600MC pro. QHY 163M with ZWO 7nm NB filters, Canon EOS700D astro mod
Secondary mount: Skywatcher StarAdventurer

That's a lovely repro in which the difference is clearly visible. You've certainly made progress with your processing skills :)

Hi David, not sure which I like best. Stars look best in the original, but, some more details brought out in the repro.

Thanks for sharing.

Thanks Steve,

So, by the Miracle that is StarXterminator, I have swopped the stars in the new rev with those from the original. And I think you are right , it is a bit better that way.
