Thanks Greg.
The reducer if anything makes the stars a tad tighter, there is absolutely no CA.... but I hear you when to comes to back-focus!
I had to get second cover-plate for the CFW adapted solely for the reducer.
Yes there is some fringing around the stars, but purely due the seeing varying during the exposure sequence.
I guess I could have "fuzzed" it out, but didn't want to lose the snap...or as Andy aptly said "Bam!" in the data
I rather like the structure in faint fuzzies at 2 o'clock. Faint.... but beautifully resolved by this instrument.[/QUOTE]
You can always do some decon on the subs that are enlarged. That has a certain workability.
I quite liked imaging with the reducer apart from in my case having to slum it and use a guide scope. Something like the outer parts of the Helix in 2x2 binning is about 4 hours worth of exposure. You should have a lot of fun with it as its obviously top of the line optics.
Greg.
