First light with new scope

[ace2029]

Good morning all!

Excellent night last night, clear sky and a bright moon.  Got the 130PDS used with the Baader Hyperion Zoom eyepiece, Zoom barlow, T2 adapter and a Canon EOS 500D.

I don't have motors as yet.

Please see the attached photo of the Moon - would anyone be able to explain the blue edge around the left side?  Is this because the Moon is not being tracked or is something else at work here?

For this shot I was using the eyepiece only, not the barlow.  I don't have a coma corrector - would this rectify this problem?

Currently investigating how to achieve focus with the camera on the eyepiece and the barlow - can't get the camera far enough away from the tube!

Many thanks indeed!

I suspect the blue is chromatic aberration ( where the eyepiece can't focus all colours in the same place ) if you attach the camera directly to the scope it should be better , nice start though

Chromatic aberration.

Basically your lens is producing a prism effect.

You'll find that it doesn't happen with dso targets
