Which filter did you decide on? I’m thinking about those exact filters too.. more so between the d1 and the altair cls-ccd.. curious to know your experience.

Thanks for the info! The reason why I got pempro is because I’m noticing a particular jump that occurs at a specific time, it looks like periodic error. I was getting great guiding at rms 0.98” or so, then last week sometime I noticed this jump happening at the same frequency of time. Then I started getting an rms of 1.8”. I hadn’t needed to throw away any subs, then had to throw away three one night. Pempro seemed a bit expensive, but someone had recommended it. I havent tried eqmods autopec.. but I guess I’m stuck with pempro now, can’t typically return softwsre, so I’ll give it a go and see how it goes. i checked out the manual and found that the worm gear has 180 teeth! Just in case anyone else is using pempro.

I just got pempro in hopes to tack periodic error. It’s asking me for the worm period based on how many teeth there are on the gear. Does anyone happen to know this value? thanks
