I have a Meade 8" LX50 I bought in 1999, which is deforked and rides on an Atlas Pro mount. I put a Moonlite focuser on it last year to enter the autofocus world and be able to deal with the mirror flop. Imaging is with an ASI1600MM + filter wheel + ZWO OAG. I have a Meade 6.3 reducer/corrector as well.
No matter how much I adjust the backfocus I've never felt like I could get the Meade reducer set up quite right. There always seems to be coma and curvature around the edge of the frame. I've considered selling the LX50 and replacing it with an 8" ACF tube to get the UHTC and ACF optics plus the mirror lock. I'd be ok with imaging at f/10 with the ACF as I do ok guiding with the OAG and this is used mainly for planetary and small DSOs anyway (refractor for the larger targets). That said, I'm wondering if the better option might be to replace the Meade reducer/corrector with something like the Starizona SCT Corrector II (https://starizona.co...oma-corrector)? It's $399, but if that would do the trick then I'd be ok spending the money for it. With the 4/3 sensor on the ASI1600 I don't know that I'd reap all the benefits of the ACF design in the first place and being in the autofocus world has largely mitigated the mirror flop issue.
