Nice report. Thanks.
I have recently had a chance to compare the two Celestron zooms. One is an OTS 8-24mm the other is the 8-24 that came with my 'Regal' spotting scope.
I've been testing them in my 4" / f8 refractor and a borrowed 8" / f5 Newt.
The 'spotter' is a noticeably better eyepiece in either scope. Sharper, better contrast and with less scatter. On Jupiter the spotter zoom also had a slightly warmer tone and showed some festoons and clearly delineated banding. Colours were also better rendered and where the OTS zoom showed noticeable CA, the spotter showed little or none.
I've not seen this EP for sale separately from the scope, but it would be interesting to see it up against the Baaders.
Now if someone would get it together and produce say a 10-30ish zoom, I'd be dead happy.
Thanks again for a great report.
Peter
