I see that Andrews are selling these at $149. I've been using a CCD camera for imaging and the edges of the images obviously need something. My concern is can I achieve focus if I use one?

I am waiting for a reply for this question as well. I think that a spacer of some sort might be required to get the corrector at the right distance.:shrug:

Buy the SW f/5 coma corrector, about the same price, and no need for spacers, works out of the box.

Nowhere near the same price at $249! At astroshop.com.au priced at $360!

After reading this review it made me wonder if its best to spend the extra $ for the SkyWatcher corrector.

This review is a few years old so maybe GSO have improved their corrector since then?.

There was someone on here a few months ago asking the same question, he ended up getting the GSO and regretting it eventually changing to either the Baader MPCC or Sky Watcher after never getting the GSO Scoma corrector to work very well.
