  1. I did fiddle about with balance but usually keep it east heavy. Never checked the balance by pushing on the weight bar with my finger, though so I might as well give that a try. Thanks for the tip The mount was rebuild last month and both axis should be as tight as I can possibly get them without running into binding issues. I was thinking about readjusting the worm gear tension/engagement and belt tension while tracking a star but I'm not sure if that is advisable. There is no obvious play in the image train and I'm fairly certain that the camera is perpendicular to the scope.
  2. You got me worried there for a second. Elongation is in RA and I do leave time for the guiding to settle before taking the images.
  3. Thanks for the quick responses guys! I did apply all the recommendations and took a couple of images of Regulus to test my guiding performance. With an integration time of 2 minutes most images showed elongated stars. I did try to increase the exposure time in a pre- vious run but I did not see any major improvement that couldn't have been down to a difference in seeing. Guiding parameters were set to default prior to the guiding runs that I posted to make sure that the issues did not stem from my phd2 setup. I followed the following steps to record the PEC curve: 1.
  4. Hey guys, I had hoped to circumnavigate my ever-present guiding issues by buying an expensive mount. Corona made short work of that pipe dream and now I'm stuck with ye olde AZ-EQ 6. I decided to strip down that old hunk of junk again to make sure that everything was lubed up and ready to go once the clouds buggered off. Tonight was the night and as always I didn't take any pictures. Instead I was futzing about trying to find the source of all my woes. Polar alignment was done using polarmaster and the guiding parameters were set according to the recommandations of the g
  5. I have had a number of problems with Telescope Service over the years, so I will probably never order anything from them again. However, they assured me that the mounts had never been opened before they were sent to me. Don't know if I should believe them so I cannot really tell you who is at fault here. The issue with ordering another one is that Teleskop Service are the only dealers that sell these mounts in Germany so I would have to order one directly from Avalon Instruments. With the issues I experienced I'm not sure if I want to take that chance. I would have to pay for return sh
  6. The problem for me is that I no longer have the patience to deal with any teething issues. I understand that new products will always have kinks that need to be ironed out. But two dead motherboards within the first two years seems like a bit more than a kink to me - especially considering the price of the mount. I've spent the last 4 years trying to get the tracking on my Skywatcher AZ-EQ 6 up to an acceptable level - without success. I just need a mount that works right out of the box and that I don't have to keep tinkering with. There is also the somewhat more personal problem that I have i
  7. Apparently, longer telescopes can potentially hit the RA drive housing, preventing you from imaging parts of the sky. The guy had to install longer risers under the saddle himself to alleviate this problem. The saddle clamps also don't have enough travel to accommodate dovetail bars that may not perfectly follow the losmandy design specification. Apart from all of that, there were a lot of problems with the tracking behaviour in the RA axis that were dismissed by GTD as user/software errors. However, it turned out that the RA motorization was faulty and the whole mount had to be sent back to I
  8. I did talk to someone at CN who just took delivery of an E.Fric mount and had his share of troubles with the thing and I heard plenty of worrying stories about losmandy mounts. So, after quite a lot of soul searching, I finally decided to go with a linear fast reverse mount from Avalon Instruments. I placed my order for a matt black version with telescope service last November and finally received my first premium mount in the first week of December. However, things didn't quite turn out the way I hoped or planned. I was rather smitten with the mount the first time I opened the
  9. They do look nice but The internet really is a wonderful place for a pessimist like me. The reason why I'm a bit skeptical towards the Losmandy mounts is that their worm gears are not belt driven and the spring loading mechanism is only fitted to the dec axis - at least for the G11-T. They may work well if maintained and adjusted properly. However, I don't have the time to constantly fiddle around with my mount. I just want a setup that's portable and easy to maintain. How pronounced is that issue? Does a breeze already affect the tracking performance or is only a strong wind
  10. I'm toying with the idea of buying a new mount in the 4k€ to 5k€. I am looking for a mount that is still portable enough for me to schlepp it to a dark site. Maintenance should be as easy as possible, setup straight forward and guiding as easy as it possibly can be. I have had major issues with a Chinese made mount so I'm trying to stick to western manufactures for now. After some research I have narrowed the list down to the following three mounts: Vixen AXJ Losmandy G-11t Avalon LFR Of the three choices I am most impressed by the G11 - I like the modular design and th
  11. I wasn't sure if I could set up a OAG in a timely manner, so I got my hands on a ZWO ASI 178 MM instead - just to check if a better match between my guiding/imaging setup would do the trick. Pixel scale was 1.42" and 1.98" for the imaging and guiding rig respectively. I guess this is as close as I can possibly get the two without buying a different guide scope. Unfortunately the results aren't all that encouraging. I used the standard parameters as well as the suggestions from the guiding assistant. I also gave the PPEC algorithm a go but I still have trailing stars in my images. I
  12. I only saved an image of the graph once the corrections were turned off. Having unearthed the production mishap in the R.A. axis I was starting to get worried that the gears themselves were bend. I figured that the best way to visualize any worm gear problems would be to record an unguided graph. I have to be honest though, half the time I don't know what I'm doing^^. I had lowered the MinMo values without much difference to the guiding performance. I did not, however, consider the different pixel scales between the imaging and guiding scope. I guess that's what you get for buy
  13. Hi guys, I've been having a lot of issues with the R.A. guiding of my Skywatcher AZ-EQ 6 mount and I can't seem to isolate the source of the problem. This PHD2 (unguided) graph and guiding assistent was last week while I was experimenting with my mount. I have also uploaded the PHD 2 log file in case anyone is interested. And here is the equipment I am using: Equipment: Skywatcher Esprit 100 ZWO ASI 1600 MM C (imaging) ZWO EFW Mini Starizona Microtouch Focuser Borg 50mm f/5 guide scope (incl borg helical focuser) ZWO ASI 174 MM (guiding)
  14. Is there any news on the Astrotrac 360? A lot of vendors here in Germany switched the delivery time from '1 - 2 weeks' to 'unknown'. Seems to me that they missed their delivery date.
