Egg-shape stars Bresser exos2 goto
chrobakx replied to chrobakx's topic in Imaging - Image Processing, Help and Techniques
Alright. Finally I had the time to test everything. Great news is there is no more star trail on unguided tracking. 60s subs are fine with nice round stars. Guiding is improved as well, but it still required fine adjustments. New bearings definitely work better than old ones. -
Honestly don't bother with the polar scope, if you can use guide scope and sharpcap for polar alignment, very quick and easy. Regarding the controlling mount with the laptop, you have to check wether you have a 2.3 firmware. If yes then you'll need the Ascom driver(very basic) and USB cable. I can use the Carte du ciel for control. Edit Here is the link for the cable. https://astro-gadget.net/gadgets/cables/exos2-gt-rj9-usb-pc-interface-cable-3m-for-bresser-exos-2-goto-eq-mount If you have 2.2 firmware, then you better buy the Bresser cable and update the firmware first https://www.bresseruk.com/BRESSER-Computer-Cable-for-Remote-Control-of-MCX-Goto-Telescopes-and-EXOS-II-EQ-Goto-Mounts.html

chrobakx started following Barbell shaped stars - is this Periodic Error or Backlash ? and EXOS GOTO Mount
-
I have the Bresser exos2 goto. Make sure the cables are connected as in the picture. Also do you have a power source with enough amps? Please post a picture with complete mount and everything you got with it. Thanks

Another update: Worm bearings are finally replaced, worm gears and motors adjusted. Now as before I need a clear sky to test everything properly. -

Quick update. While I'm still waiting for the clear sky, I had an idea to swap DEC and RA worm gear housings to see if it will make any difference, because in theory DEC axis isn't moving so much and thus should be less worn out than RA axis. When I removed DEC worm housing I noticed the bearings wasn't moving freely, even after cleaning and adjustment, it wasn't as smooth as it should be. So I ordered 4 new bearings mr126 ZZ for both axis. I'm hoping this will make significant change in guided and unguided sessions. -

Looking forward to next year PAS. Hopefully it won't be cancelled -
EQ5 Deluxe Mount Motorising Options?
chrobakx replied to Ian McCallum's topic in Discussions - Mounts
Second that. I had this kit on eq3 mount and it was easy to use, tracking was spot on. No issue at all. I replaced the 6V battery holder for power bank. -
Here is my cheap and simple solution for my skywatcher 150p. I built it based on this thread: Total cost was I think £12. It's working like a charm. It's smooth.

I agree with the focus, I'll fix it next time. But I disagree with the faster speed. PHD2 is sending two signals to RA motor. First the beginning of the move, then the end of it. It's not pulsing guiding despite the using Ascom driver. It's very basic goto mount. If I'll increase the side rail speed, mount will be chasing the signals from PHD2 and guiding will be even worse. It won't be able to keep up. We can talk theory as much as we can, but I need the clear sky to test all suggestions. -

Not ST4. USB to camera and usb to hand controller via Ascom( very basic version). -

I think it's on default speed, I tried to change it before, but unsuccessful, I don't know why. I'll check all the settings again. Lots of good suggestions. Edit: I realised, I'm not using EQMOD. I thought you was talking about settings in PHD. I know there is a option to change the side rail speed. -

Hmm interesting, I never paid attention to this, I didn't know what it was doing. Thanks for pointing out. I'm always trying set up guiding speed to 0.25. I think the default is 0.5. Next time I'll set it to 0.125, that's the lowest speed in the controller. The thing with this mount is, even when I'm using Ascom driver, it's still sending signals just like when I'm using ST4 port, not pulsing signals. It's was proven. So the slower side speed I'll use, the more time will have the mount to react to signals from PHD2. I've been imaging last night with guiding. I took the screen shot of it, but it's in my laptop. I'll check the RA error later tonight Now I need clear sky. Thanks -

I did that and I found tight spot actually. It was maybe on the on 1/4 of the RA drum gear, so it's not nice round anymore(who know if it ever was round from factory). -

Also I'll have to do new calibration in PHD because mount was disassembled and there is no backlash. Thanks for help.
