I’ve been using my 8’ Edge HD on an Evolution mount for a couple of years now and I added a wedge to it a few months back. Using SkyPortal with StarSense I’ve never really had any major issues getting it aligned.
Last night I was setting up to photograph Mars and went through my normal procedure. StarSense took its images but, after confirming success with the third plate, instead of just winding up a bit and parking it proceeded to pitch the ota towards the north well below the horizon.
Fortunately nothing snagged. I skipped the ASPA and instructed it to goto Mars and was surprised to find it was spot on (better than usual actually).
Anyone any ideas why it took that nose dive? Thanks.

Hello everybody on this community, very happy I recently joined stargazers lounge.com
Last November I was able to modify my EQ5 mount via shoestring astronomy GPUSB (ST4 mount-USB laptop, my guiding camera is connected to the laptop by USB and PHD2 as guiding software) so I can autoguide it for long periods 6 minutes and more, I was really happy that this project was achieved and now I can get more details out of deep sky objects.
My question is how can I go GOTO with this set up, trying to find objects to image is really time demanding without GOTO, and my goal is to take advantage of time to get those photons.
I installed already ASCOM but I didn't connect with the USB connection (I think only work with serials cable)
Thanks in advance for your valuable comments
I have recently bought a Orion Starshoot Autoguider. I downloaded phd 2, eqmod and ascom stuff. After a small research I found out my mount (exos 2 gt) doesn't support computer acces without firmware upgrade and fancy cables but I have the st4 port so it shouldn't be a problem. In phd I choose camera as Starshoot Autoguider and mount On-Camera. Aux mount and AO are both none. My wiring is one cable to pc from camera and another to st4 port from camera. When I started looping I selected the star with no problem. I choosed the one star alignment option from my hand controller and after centering the Archturus in the middle of view I pressed ok and it was successfull. I started guiding and after a while I get the error: RA calibration failed star didn't move enough.
I connect my mount to PHD2 using ASCOM and most nights I have the error "Star did not move enough" as well as "Suspicious blah blah, axis may not be perpendicular". This does not happen when I connect the mount via ST4 cable. I read somewhere that I can do a Calibration Sanity Check in PHD2. I am however unable to find that function in the software. Is it some pop up feature or does it have a location in the settings/brain icon?
Any help will be highly appreciated.
