Last week I discovered a reasonably wobble on the RA axis on my HEQ5 which ended up causing lots of double stars on my subs (i am guessing because the mount kept wobbling between the two positions.) So I did the worm gear adjustment and the wobble seems to have disappeared. I did a full slew rotation check and couldn't tell any binding/grinding (I had binding at 1st attempt but was resolved after further adjustments). Thanks to the clear skies last few nights, I had it running throughout the night 3 times now. My overall guiding is much better than before, averaging between 0.6 and 0.8 Total error. However, when the mount gets closer to the home position (usually after 2-3am), I seem to start having tracking issues. I have attached screenshots to show examples; sometimes it's trailing, sometimes it's double stars, and sometimes it makes a u-turn to track back to the original position. PHD log files from another night are here: https://openphdguiding.org/logs/dl/PHD2_logs_tych.zip Is this a balance issue that becomes apparent when the mount is more vertical? I'm relatively new to using this mount, so most of my previous sessions have been closer to the meridian. Or is my worm gear tightened just a bit too much and causing issues? I can't really hear anything wrong when slewing at high speed. Only other thing i can think of is, I sometimes get error messages on PHD but pulse command being ineffective, but these happen at other times as well without causing any issues. It's losing me 7-8 frames over the span of 2.5 hours, so it would be nice to get it resolved if anyone has any ideas? Thanks
Hello everyone, I am a bit of a newbie to astromony. Thought I would have an interest in my retirement. I have recently built the EagleMoss Solar Systemwith no problems and thought I would carry on to build the Earth, Moon and Sun Orbiter also. However, while in the process of this I have found a problem- two gears mounted on the central column are too large to mesh with the gears on the central shaft. Since these models started way back in 2008?? it is possible there have been design changes and/or manufacturerer changes, I am only guessing. If there have been major changes it is possible I have parts from before and after. All I know is I have reached an impasse. I am interested to know if anyone else has had any issues with the Tellurion. Best wishes to all and many thanks in advance of any hellp.
Any one around St.Helens area could have a look at my EQ5. Went out last night aligned with Arctutus and Vega went to 2CVn (Canes Venatici) mount moved as it got to the perpendicular heard grinding and whirring the mount beeped to say in right place. Tried going to Jupiter mount slew over then dipped well below Jupiter tried aligning with Jupiter then going to the moon slewed over and it dipped right below the moon. In both these scenarios when I pressed the up button the mount slewed up to get the targets in FOV so one motor is not working properly not sure which one. Any help most welcome.
Hi all, Absolute newby here - my first foray into astronomy. I bought a Saxon 1400mm 6" refractor secondhand complete with a EQ mount for a bargain price and I'm keen to get it working properly for both planetary and deep space observations. I invested in a few extras such as a laser collimator and a 3x barlow. I think I have a handle on how it all works including the EQ mount. I took the scope out for a test over Easter - which just happened to coincide with a ISS transit of the full moon. Rippa, I thought, that would be great to capture on my first night of observations. The problem I have is the complete inability to focus the scope to anything like sharp enough. I have some photos I took with the scope attached: The scene with the normal camera lens for my daylight practice session A shot of a distant house with the telescope (using a Nikon D7000 on a t-mount adaptor) The same house with the barlow attached A shot of the moon- no barlow - as sharp as I could get it - certainly no way to see the silhouette of the ISS with the scope this out of focus When I was collumating the scope, I noticed a that the reflection on the primary mirror was not a single spot but rather a line ... which means that the laser on the collimator target is a line rather than a dot I confirmed that this is not a problem with the shape of the laser beam coming from the collimator by showing the shape on my hand at a distance of 14m I'm not sure if the distortion of the laser is the fault of the secondary mirror or the lens(es) in the bottom of the eyepiece mount. I'm also not sure if this distortion is what is causing the inability to focus the scope, but I suspect that both issues are symptoms of the same problem. I'd appreciate any ideas on what to do next to resolve the focus issue.
Hi I have the ZWO ASI120MC-S and I just can not seem to be able to calibrate it, tried everything I can think of, can not find much online. Any suggestions really appreciated as I'm randomly punching numbers hoping for results, I have a rough idea what the variables are going into but no luck. This is the best I can do sat here in bed with the bed light on.
