Auto focuser - ZWO, Pegasus, Deep Sky Dad, other?

Hi all,

I'm looking for an autofocuser and wondering which way to go, if there are any to stay away from, or which ones people have had consistent success with.

I have a Crayford 10:1 style focuser.

Thanks

I use a zwo focuser, works pretty well and you can get extras such as a hand controller and external temperature sensor. Has quite a bit of backlash though I had to use a dial indicator to get it dialied in, I'm not sure if this is typical of all focusers or just the cheaper ones. Is this a gso crayford? If it is you will need to make a bracket for it, the only turnkey solution for them that I'm aware of is the lunaticoastro focuser that has a bracket.

I have the Pegasus focus cube 2
I comes with temp probe & all fittings required
I also purchased the optional manual controller for when I do visual
It all works extremely well
I purchased this from Cyclops Optics, no hassle with dealing with them at all & shipping was extremely fast considering it comes from Hong Kong ( last shipment was purchased last Saturday & arrived on Thursday , I purchased the manual hand controller for focus cube )
I used this on my WO132 rack & pinion focuses, using SGpro
I run automatic focus & get perfect V curve & pinpoint stars



Good luck

I have a ZWO one. You don’t specifically need a temperature probe with them as they have a sensor built in as well, though they don’t seem to advertise that. I didn’t buy a hand controller as I drive it via software for astrophotography. I have not noted any significant amount of backlash in it. I use about 100 steps to tame any backlash between it and the focuser on the scope itself.
