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!!
(slightly)Higher Res...
