Re: Thread pitch..
¿ªÔÆÌåÓýYes, that¡¯s my guidescope.. I am aware it may not work, but it better because if I have to go to an off axis guider, I would have to also replace my filter wheel and filters too.. None of them are the ¡°thin¡± variety and I cannot reach focus in the Raptor.. The goal is to mount my ADM Laser Finder.. My camera chips are small and sometimes an object lands outside the FOV, so I just reach up and switch on the laser and I can see which way I need to move.. I also *really* want the two scopes to be on the same object so I can easily swap cameras, so I don¡¯t want a clamshell.. ??? But it may not work at all.. First I have to make it guide at all.. On my Dec axis, the PHD Guiding assistant shows a LARGE time lag when I switch directions AND all the data points it shows on that window are double points.. I am aware of all the different ways to deal with the Dec.. Guide in one direction only.. Don¡¯t guide in Dec at all, etc.. Just got to try it and address the issues as they appear.. I am not very hopeful it¡¯ll work, and certainly not the way I want it to, as I am not doing wide field with a large chip.. ??? We shall see.. ? Derek ?

I avoid rings like the plague for anything but a finder scope because they are so prone to flexure and movement through the night that for me they really make for poor guiding. If that is your guidescope and you are adding more stuff to those rings? Sounds like trouble brewing. ? You might consider more of a clamshell type of mount for your guidescope? Prime luce has something like that I used on my tak sky90 and it holds everything really nicely ? Brian ? From: [email protected] [mailto:[email protected]] On Behalf Of Derek C Breit ? Maybe, though I don¡¯t think the Losmandy adapter will fit there so I think it has to go in a different set of holes.. If you look at the guidescope rings, the image shows 4 sets of adjustment screws.. It is also drilled to use only three sets.. So there are seven adjustment holes that are all the same size.. Once the rail is on, I would be attaching the adapter.. The adapter is the same as the base of the guidescope rings.. i.e. remove the rings and what is left is the adapter.. ? Probably will have to use the ¡°side¡± holes.. Let¡¯s see if I can attach an image in this group.. The empty ¡°side¡± holes are easily seen.. ? Derek ?

Valente ? Derek where do you want to add a rail - on top of the guidescope rings? ? On Thu, Jan 2, 2020 at 8:12 AM Derek C Breit <breit_ideas@...> wrote:
