I know this is a bit early for this but what is everyone’s thoughts comparing the two to use on a Skyguider Pro (this will be with a full frame DSLR)?

Redcat should be better, but only should.

Not sure why but I think I have read that someone suggested the Redcat is specified for a full frame but an APS is a lot safer bet.

 

A lot will depend on how good the QA is at WO. The problem is that anyone here buying a WO from one retailer tends to pay the extra to have it examined and set up by a specialist. Some even then are rejected as being unable to adjust. That option is not available to you.

 

I would like a Redcat but only if prechecked. My other problem is I already have the WO-61 and flattener so cannot seriously justify considering a Redcat. But still I do like them.

I have the AT60ED and with the flattener it performs very well with my full frame a7s and with my APS-C Canon. Stars are pinpoint to the edges but full frame starts to show some vignetting. It also doubles as an excellent ultra portable travel or grab and go visual scope.

I am not sure how the redcat will perform but would be interested in some direct comparisons.

I think it might boil down to the kind of experience you prefer i.e. a wide-field scope that can be used for imaging vs. a wide-field lens that can be used for visual in a limited way.

I'd only think about a field flattener for my AT60ED if it would improve the view for visual.
