James, thanks for your comments.Do you find collimation stability and any mirror shift a problem? Particularly after any slewing or median flips.I know these can be problems with sct’s but have the newer versions improved on this. I know Meade have a mirror lock. How about the celestron’s. I plan to use an automated draw tube focus.Cheers eric
