Drjolo, What software are you using to control the mount? Explorestars? Something else?

Thank you! Good to know. Asking because the Scope's not here yet and I want to get the mods list sorted out before it gets here. I have the Skywatcher electric focuser on order as well. I've seen the videos and it's a bit of a fiddle to adapt it - the crayford gets taken off, disassembled, focus motor installed, and then reinstalled with the base turned 180, so the motor points to the rear. And hopefully it's all square when it's done. So that's the time to cut the drawtube if it needs to be done, then blacken as needed, etc., etc... Re: MPCC spacing... yeah... I'm expecting some fiddle on that score. I do have the various Baader shims, from wrestling with field flatteners for the refractor I'm retiring. But my T-ring is a Baader as well, so maybe it'll work first time. But if it does, I'm buying a lottery ticket!

Thanks, but I'm waiting for my PDS to arrive, so I'm trying to determine the probable necessity of this kind of mod in my situation, not potential 'Max'. Restated, with better precision: Given a 130PDS + Baader MPCC III, T-ring and filter + DSLR, did you experience drawtube protrusion into the light path, while in focus and imaging?

Hi! I've searched on this and found quite a few hits, but some of the responses are conflicting and I'm having a bit of trouble figuring out what's what. Sorry if this is old ground... Given a 130PDS + Baader MPCC III, T-ring and filter + DSLR, did you experience drawtube protrusion into the light path, or not? If you did, and you corrected it, how much length did you need to cut off the drawtube, or alternately, how much did you have to move the primary up? Thanks!

Thank you all for the warm welcome!

Hi! I'm into astrophotography and will be retiring my refractor in favor of a 130PDS. As stargazers lounge is ground zero for PDS's, here I be. Been lurking for a while - time to sign up! Backorders are common these days, so it'll probably be a few weeks before my new scope and miscellany arrives from the good folks at FLO, but I'll be dropping a few questions here in the meantime, if that's all right. 🙂 Other details: EXOS2 PMC8 mount, Modded Nikon D5300, various filters, guidescope, etc.
