Hi, everybody. Does anyone have experience with telecompressor and ACF? I've heard that it's a problem.

Thanks for your insights.

Vin,

 

I have an LS 8 ACF and use an f/6.3 on it for visual astronomy.  There is a  tiny bit going on around the edges, but it is not bad.  Yes, the have corrected out some edge things in ACF, which makes some of the correction in the telecompressor over-kill, but I do not find it overly objectionable.  The error seems to deminish some if I put in an extension piece after the telecompressor and make it something like f/5.0.  The scope is not corrected all the way out to those edges and that seems to offset the over-correction in the telecompressor to a certain extent, at least to my eyes.

Thank you MB,

I just wanted to know whether it makes sense for visual observation and astrophotography.

Thanks 

Vin

Does anybody know if Meade is shipping the rumored F5 telecompressor for the LX600 now or not. If someone has one can you write a report here?
