M35 / NGC 2168 w/NGC 2158

This image exhibits severe coma at the edges. The result of my forgetting to remove a 48mm spacer between the DSLR and the x.85 field flattener!! I will be trying this one again, but I think I got the subject framed well.

Awesome!

I just looked on Wikipedia and learned that M35 (NGC 2168) (the large open cluster) is about 2800 ly away, and the compact cluster, NGC 2158, is about 9000 ly further away. Apparently 2158 is an open cluster even though it looks like a globular cluster.

Very nice Ron! Your image is inspiring me to get out there again and have a go at seeing both of those visually in the same eyepiece FOV. I think I can, I think I can...

Nice Ron!

Ok, so this is more like it. Redone from scratch, but the first attempt was still good learning and hopefully someone else will benefit from my mistakes!

Very nice Ron. The original image was very good but you are right the latest image is supurb.

ditto what Don said.

Thank you. Glad you enjoyed.

Amazing how little separation was required to introduce coma into the original. Nice flat field in the second one and I was able to add .4 hours of frames.

Shooting these frames with the tempurature down to 16 degrees didn't hurt either. Kept the T5i sensor nice and chilly.
