Hi A very newbie question here but for the life of me cannot figure it out.
Have an EQM35 goto mount linked through a skywatcher wifi dongle to a synscan pro app on my android galaxy s9 phone.
I van use the app but have a couple of things that are either greyed out or dont operate when pressed:
1. Point and track
2. Doesn't seem to track (tried the.moon) using lunar tracking but mount doesn't move
Thanks in advance for your help.
sorry if this was already posted, i'm looking for a flattener/reducer for my William Optics Zenithstar 66 SD (already asked WO by email) they reply me that since this product is discontinued over 10 years ago, i need to look for
FlatII, FlatIII - with 2"sct thread
Flat6a with 2"SCT adapter
and i saw this one https://www.firstlightoptics.com/reducersflatteners/william-optics-adjustable-flat6a-iii-08x-reducer-flattener.html
and this one https://www.aliexpress.com/item/32917167365.html but i'm not very sure, so i'll ask before buying anything
i will use it on my recently buyed star adventurer classic (buyed on FLO)
Thanks in advance

i'd like to share with you the design, making and progress of a project my astro club endeavoring to. I'll post here relevant info in a run-up to where we got to so far.
Here is the mission: 800mm in diameter. That's it. A lot of inspiration out there but it needs to be able to do science. So it's a relatively fast Newtonian capable of tracking for tens of minutes.
So we realized that we were facing 2 projects in one. The mirror on one side and the mount on the other. Shall we start with the mount? What's the best compromise in terms of ease to build and cheap components and the chance to have a stiff yet light structure. An alt-az, like the biggest telescope! - or rather a glorified dobsonian in this case.
Any comment/suggestion is welcome!
As my GoTo is successfully finished (some cosmetic issues remain) I shoud focus my attention on planets' positions. I have proper source of information: fantastic book "Astronomical Algorithms" by Jean Meeus, thus I will sort the planets soon. But planets are not a challenge for me at this moment, they are just something obvious to do in my list.
I have another idea and ambitious plan for next project within the year: locating and tracking the ISS to be able to make a video of its fly, not only transition.
Similarly to other objects, I need some equations. I'm pretty sure they are available somewhere, because plenty websites or apps offer showing current position of the ISS.
I will use this topic for sharing a progress ot the project.
