Rough M42 widefield from the Astro 40D

[dugnsuz]

Hello all,
Tracking problems plagued my M42 attempt - also the 70-200mm f4L IS + 1.4x Ext isn't a perfect marriage.

Soft stars, CA, blown out core - Baaahhh!!! Whatever!!!!

Astro 40D (running around -13ºC)
Canon 70-200mm f4L IS + 1.4x Extender
FL=280mm, iso1600, f5.6

Rough, but with a certain potential!!:P

(slightly)Higher Res...

So cool how everyone gives their own little twist to an old favorite! This one's got a funky 'electric' feel to it - I like it! :thumbsup:

I did a quick fix of (some) of the CA issues and ran it through a field flattener - hope you don't mind!

No worries Ivo - fire away!

Bit of a lost cause this one - but I enjoyed the fact that the cooled DSLR allows me to stretch the image enough to bring out the gas/dust.
Made the mistake of using an aperture mask over the lens at the expense of fine detail - and redundant due to tracking/CA problems.

That Astro40D seems to be keeping its cool. Would like to see what it can do on the Witchhead. Craig

Bluudy oath Dougie potential there for sure!

Some correction issues but not that bad really so get everything sorted and hammer away for a few hours at a dark site and man, you could have a purler for sure, t'is already pretty good :thumbsup:
