Hi Peter,
this puts things in a little bit of perspective for me...
The blue star in your field is the sucker that's casting blue reflection to my top corner.
This is a good get I'd say and showing some promising detail for the amount of time you spent on it!
I used the GSO 8 inch F4 reflector, so 800mm FL. I just noticed you are from streaky bay, lovely part of the state. I actually enjoy the blue reflection in your image.
