Super Wide 135mm of the North American Nebula in SHO.

Having fun with the Samy 135mm set at f/2.8! :)

When the first Ha sub came in I was shocked how much signal there was at 90" only!

I wasn't able to get my guider hooked up with my new connections, so I went unguided with a PEC and it worked. Old school going unguided - I enjoyed it!

Also very impressed with the lens, a bit difficult for perfect focus but it seems to hold focus very well.

Thanks for viewing! Clear skies and stay warm :)
