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?
Question, is my pier out of level if I'm trying to PA (with asiair pro) and both directions are moving when I adjust the alt bolts? I can't get the mount polar aligned.
Mount neq6 pro
Pier mounted on a concrete slab
OTA c8 with .63 reducer
Camera asi294mc pro
Thanks in advance
I know it may be a bit of a long shot but I'm looking to buy a HEQ5 Pro mount or an NEQ6 Pro or something similar. Preferably belt driven but not necessary as can happily modify it. Please let me know if you have anything! Thanks.
Beginner here who is really struggling! Apologies in advance if this is long! I only began pointing my camera up about two months ago. I have a Canon T7i. Last week my Star Adventurer Pro arrived and the frustration began. I’ve watched countless videos and know what I’m “supposed” to do - but it seems to all go out the window when I’m fumbling in the dark. I realize these questions are probably silly, but I can’t seem to find an answer online. I’ve only had three clear nights so far to practice and there’s been some improvement, but I’m way off! A pole master and/or guiding is not in the budget right now.
Polaris - tripod pointing north. Level it properly. Set altitude. Look through and see so many stars and they look almost equally bright. How do you know you’re on the correct star? Last night I went out at dusk (can’t see Polaris from my yard so I have to lug everything to a different location) and that helped tremendously, as it was the only star there. But that’s not practical long term... can’t always head out that early. Should I get a laser pointer? Any other tricks or tips?
PA - last night was the first time I had even marginal success. With 0 up and 6 down, I used an app to get the correct position of Polaris. I was not perfect, but close, which was a huge improvement in itself for me! I set up my camera with a Rokinon 135mm lens, balanced it, moved it to roughly the position I wanted to shoot, checked my PA and it was slightly off so I readjusted. Some time goes by and I’m noticing anything over 15 seconds has very noticeable trailing. Polaris is way off when I look in the scope. My axis is obviously turned to position the camera and I had no idea if I’m supposed to be repositioning Polaris to where it should be on a clock face - ignoring where the 0, 3, 6 and 9 are actually showing - or to realign to where it would be in relation to the numbers. I hope that makes sense! I ended up positioning Polaris where roughly 9 would be (as it was shown on the app by this time) and ignored that the number 9 was in a totally different position in the scope. Still could not get any images over 15 seconds without trailing. I’m sure my polar alignment wasn’t perfect when I started - before it all went totally to hell - but I really thought I was close and should’ve been able to get longer exposures. Any help or advice appreciated! It’s so frustrating when you go through your checklist and think everything was done correctly only to realize you screwed up bad somewhere.
Balance - thoroughly understand and am able to properly balance my camera and counterweight. But I am certain that I was throwing my balance totally off when I would loosen the clutch underneath and rotate the actual camera to point in a certain direction. How do you compensate for that? The idea of moving everything back to “home” position and starting over can’t be right! Lol
Anyone who stuck with me this long - thank you!!! This is completely new and overwhelming - yet very excited to learn. I don’t have the gear to get the amazing pics I see here, so trying to learn with what I do have before investing any more money. Have recently purchased the tracker, ordered a new tripod and bought two Rokinon lenses. Hubby has had enough! Lol
Equipment - canon T7i, Star Adventurer Pro, relatively inexpensive tripod until the Star Adventurer one arrives, have only tried using my Rokinon 135 lens. Need to master that before I attempt anything heavier. I also have an intervalometer.
Last suggestions needed - clip in filters? Which are a must? I have photoshop and Lightroom but see so many other programs. What should I consider getting down the road for post processing?
