The first two photos were taken using my BST StarGuider 3.2mm ED EP. The middle one was using a 25mm MA EP. The last two were taking with a 10mm MA EP.
I was just holding the phone to the eyepiece, using the zoom and exposure compensation. I have no control of the ISO with this phone, even using the Open Camera app.
Wim has wisely persuaded me to go for an eqdir cable from my RPi to my SynScan controller. I currently have a usb:db9 + db9:st4 setup to the SynScan handset (ie 3 cables connected). Can I just change the db9 to st4 to a db9:Rj45 or similar? Eg:
Plus an old ethernet cable? Ie does the pinout of an ethernet cable correspond to the pinout of the SynScan controller handset socket?

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
Can anyone help? I'm pretty much a novice at this astronomy stuff but loving the steep learning curve. I started by using camera lenses modified to use an eyepiece but after much debate, deliberation and saving up, I have finally bought my first proper telescope. Unfortunately I now have a problem.
Last year I bought a second hand Synscan EQ5 mount which has worked perfectly each time I have used it. I used it about a month ago for the first time with the new scope (last time we had a clear sky). Everything worked as it should. At 2 am I parked the scope, dismantled everything and put it away. Nothing was dropped, snagged or got wet.
The forecast said we might get a clear sky last night. Anticipating this I got the mount on the bench, stripped, cleaned, polished and greased the DEC axis plain bearings (hoping this might help with guiding). When finished I connected the motor controller and handset and switched on. I was greeted with the following messages: INITIALISING then CAUTION BOTH AXES NO RESPONSE. If I press enter and carry on through the menus, then everything appears to be as it should except no motors run. I have tried everything I can think of and would be very grateful of advise or suggestions. These are things I have tried, so far:
Different power supply. I have been using a motorbike battery which is giving 13.5V constantly when I switch on. I have tried two other batteries with a 2A charger connected.
Continuity tested the cables from the plugs that go onto the motherboard of the controller all the way to the motors.
I made up the RJ45 and RJ12 diagnostic cables suggested in the manual and the handset appears to be ok.
Removed the motors from the mount to make sure that they turn freely.
Replaced the RJ45 cable from the handset to the controller.
Examined the motherboard for dry joints and damaged components.
Assembled everything in the tripod to make sure that the earthing tab on the controller made no difference.
I now feel that the problem is the controller motherboard but logic tells me that it was the mount I disassembled, so the fault should lie there. Is there anyone who has had the same problem or who has the same system that could help me diagnose the problem. I'm in North Shropshire but happy to travel to anyone who could help. Unfortunately I don't know anyone with the same mount.
