Quote:I've just got hold of a Skywatcher HEQ5 pro mount from ebay and have a couple of questions. I bought this mount initially for use with my 80mm ED APO, which is very similar to the Skywatcher Equinox 80 Pro Fluorite ED. My first question is what length of unguided exposures could I expect to get using this setup and a Meade DSI 3?Would 5 - 15 minutes be out of the question?My second question is what size payload would this mount be able to handle? i have a Meade 10" LX200gps and wondered if the mount would be able to handle this?I suppose thats really 4 questions.
Quote:Thanks for that Vinnie.I'd be over the moon with 7 minutes as the most I've ever been able to get is 30 seconds with the ED80 piggybacked on my LX200 in alt/az.I'm not sure how old this mount is but it does appear to be in good condition. Is there any way to determine how old they are?I've never polar aligned a mount before but I have spent many hours over the past 2 weeks looking into this and now have a fairly good understanding of getting a rough polar alignment and I'm considering using either PemPro or WCS for refining this. Do you have any experience with either of those two programs?
