If no reducer is being used, that's a scope that needs to go back to Takahashi for collimation adjustments IMO. While they're could be some tilt, it would need to be insanely large to cause that much

I just reread the other mail that he sent. I thought he meant extend the secondary out but now I understand extend the secondary baffle. Robert

Please keep us posted Emilio I have 2 GSO RCs, they are mostly sitting in the corner, but I may be inspired to re-energize them! -- Brian Brian Valente portfolio brianvalentephotography.com

Thanks Roland. Someone had already suggested to me that it could be a need for extension of the secondary by about half an inch. I have used the scope many times and this is the first time this is

John Hayes reported something similar with the baffle on his 20" CDK. IIRC they sent him a newly designed one.

>>>a telescope like the CDK20 can have a baffling issue? Yeah, but I don't want to get into any bashing here I think they recently changed their baffle design, and it turns out there were some

I don't want to goober up the AP list too much, and I do own an AP1600 upon which the scope sits, so reference to the baffle leak article would help my baffling artifact.

Robert, I have been fighting the same thing on my 12"GSO RC for years. I have a truss system. If you find a remedy, please let me know. Recently I placed protostar flock on the tube portion of
