Hi, I recently made a video of how to mount a Sesto Senso focus motor to a Starlight feather touch focuser.
I have now also made a video of how to calibrate it and also how to measure the backlash of the rack and pinion gear of the focuser.
This method is not limited to a starlight feather touch focuser but could be performed on all kinds of focuser.
I hope this video makes it easier for anyone out there having problems with backlash.
You can also check out my other videos of the focuser / focus motor here: https://www.youtube.com/channel/UCm50WzpT1YKCwghW13b6k-g?view_as=subscriber
Hi guys, I have made a video of how to mount a Primalucelab Sesto Senso focus motor on a true 3" Feather Touch 3215 focuser.
I thought some of you might wonder how to use the extra collar you need to mount the motor on to the bigger versions of the FT focusers, and also how to align the motor shaft.
I recently purchased a sky-watcher focuser for my Celestron C8 (1997) sct together with a focal reducer. The focuser threads on the sct and so does the focal reducer. But how do I use both of them together. What I've found so far is, that one must first attach the focuser to the OTA and then the focal reducer to the focuser . But I can't see how I can attach the focal reducer to the focuser. What kind of adapter would I need?
I am starting this as a baseline to find out Cons and Pros for the difference, between standard focuser and all the way to the electronic top? up to max £3k.
I mean : practical : i would like not to worry about rotating and focusing at all., so paying big bucks will give me this reassurance? - i guess? yes? - one focuser for all!!!!
I have a short list for all: refractor /reflectors,/newtons
Moonlight FT, ASA AAf3", RotoFoc 3, Nitecrawler 3, Optec TFT-53, Integra 85, Finger Lakes Atlas (FLI).. . Esatto (expensive - but complains)
i am sure there is more good stuff out there...
I am using moonlight 2" on my small triplet and FT 2" on the 2nd one. I was thinking to upgrade and open up to 3" electronic- Integra 85,
or - just find out that ASA is still making their AAf3
My tele will be fast APO 100mm and on coming 10-14" barrel... i guess RASA doesn't need one?
Please all experience welcome.
Have anyone tried to make a DIY version of hand controller for zwo eaf focuser? Or tried measuring what is the output of the controller?
I want to print a hand controller +battery case all in one but unfortunately do not have the controller to check what needs to be outputted thru connector. I assume it will be pretty basic like shortening contact but maybe someone has already checked
Thanks for looking!
