Thanks Mike!
Always fun to experiment.

Why ISO 6400 ? It causes many noise. Perhaps more time of exposure with low ISO.
I reckon that a good barlow will bring better result.

Thanks Jorge!
Why ISO 6400, that's easy to answer.
The focal length with eye piece projection is 3200mm, I'm using an Orion Mini guider which is good for 1500mm.
So I needed fast acquisition of the bug, to allow for guiding at this F/L and it was very faint with projection method.
I tried ISO 1600 at 5 minutes but not enough signal and the guiding starts to get a little wonky at this exposure time.
Might try the 8" Schmidt cassegrain with ED barlow tonight and see how that goes.
Cheers,
Justin.
