    Anyone using an OGEM mount??

    I think that JTW are walking a fine line, if not making an outright mistake. It rarely goes well to publish vapour-ware and then to release a beta test to the public. I'm minded of Lunt's situation when they were developing the Lunt 50mm solarscope. They delayed the launch date and said that they were having problems but were not prepared to release a less-than-optimal product. Yes, there were grumblings, but at that point no-one had shelled out hard cash. When the product launched it was a good 'un and universally regarded as a good product. Any misgivings were quickly forgotten. Taking money off folk and then not delivering or releasing a sub-par product will inflict far more long-term brand damage (see Daystar and the Quark). JTW are making a bit of a mess of this...to be at this stage and be in the situation of having issues with the control platform is not good.
  2. It looks like an internal reflection coming from the bright star that's on the very right-hand edge of the image. Tracking down where the light is reflecting from could be tricky....it could be the inside of the OTA, the focuser draw-tube or any extension tubes. It could even be reflections between the camera sensor, cover glass or filters. images where you have a bright star in the frame can be tricky.

    A friction drive doesn't have any worms or gears.....it's one of the systems big advantages as it gives massive stiffness and no backlash. It relies on having very hard materials as the mating surfaces. http://www.dfmengineering.com/news_telescope_gearing.html#friction

    I'm not sure that i'd want grease anywhere near a friction drive! Also any dust or contaminates would rapidly turn into a grinding paste.
  5. There's a tick box in the camera options where the fan and cooling can be disabled. Make sure that this isn't ticked. It took me a while to work out why my ASI1600 wasn't cooling (and predictably AFTER I spent ages swapping leads, power supplies and what not. )

    Mesu 200 issue??

    I'd be a heck of a lot more productive if I didn't spend hours/days/months trying to get specific things to work even when I don't have use for that function! It makes my teeth itch if I know that a bit of kit is advertised to do a particular function and doesn't even if I have no utility for that function!

    Mesu 200 issue??

    Me too. I seem to spend more time tracking bugs down and fixing them than I actually do using the damn thing for it's intended purpose! Perversely, I sort of enjoy it!

    Mesu 200 issue??

    Aha! You've solved a problem that I was having. PHD was popping that error up after calibration. I normally ignore it and it seems not to cause a problem. I've upgraded to V9.6, so that should sort it.

    Mesu 200 issue??

    Personally, I wouldn't bother with ST4 guiding. It's just one more cable and one more problem to diagnose. If SiTech can connect to and control the mount then it's unlikely to be a USB or connection problem. I have no experience of AstroArt, so I can't really comment. I use PHD2 and when I was diagnosing my own problems I found the Guiding Assistant to be invaluable. This disables the guiding outputs that are normally sent to the mount and at the same time it monitors the guiding corrections that it would normally send. Does AA have something similar? PHD also allows you to issue guide commands manually. Again, this is invaluable when diagnosing problems as you can command the mount to slew N,S,E,W with manually issued guide commands. if the mount responds then you know that the guide commands are getting to the mount AND the mount is reacting correctly to them. Any guiding problems are then narrowed down to configuration or problems upstream of the guiding software. Given that 99% of problems tend to be related to the last thing that you touched then I would be looking at the camera with some suspicion. Junking the ST4 guiding would remove a faulty ST4 port in the camera or a dodgy ST4 cable from the equation.

    Mesu 200 issue??

    This^^ It's possible that the COM port has become locked up. Win 8 handles COM ports differently to previous editions and normally frees them up without manual intervention. Have a read of this and see if it helps: https://theitbros.com/how-to-delete-com-ports-in-use/ I'd also try another USB cable. I've had them randomly die on me and throw up funny faults.

    Yep. Stainless is an upgrade option. I wouldn't fancy a friction drive with carbon steel wheels. A spot of surface rust between the wheel and drive roller might cause all sorts of issues. OK if you live in Nevada. Less so if you live in Lancashire! Its a different controller than the Mesu. The Mesu uses a Sidereal Technology SiTech controller, the OGEM uses FreeGo2 (a freeware program)

    Mesu 200 issue??

    Hi Mark, I checked mine: As far as I know, the Alt and Azi angles boxes will have question marks until you hit the "Get Angles" button. This will then poll the Sitech controller for the angles. I upgraded to version 9.6 and it looked the same. I'd also question the supply voltage. Under 12volts might be a little low. The voltage also is likely to drop once you start to slew. Try swapping out the power supply and see if that works.

    Whats wrong here ?

    According to this page, the matrix for the 224 is RGGB https://bbs.astronomy-imaging-camera.com/viewtopic.php?f=21&t=2077 This page says that the Bayer matrix for the 120 is GRBG https://bbs.astronomy-imaging-camera.com/viewtopic.php?f=21&t=2193 Based on that, I reckon that we've found your problem. you need to change your Bayer matrix setting in your stacking program.

    Other's mileage may vary, but personally I think being an early adopter can sometimes lead to frustrations. Astro mounts at this price level are a low-volume item. You are likely to end up as a beta tester. Life's too short for that unless you are into that sort of thing.

    Mesu 200 issue??

    I'll have a look at mine later and see what it says. I need to open the obsy anyway just to check that the mice and spiders haven't completely taken over!
