Thursday 5/21 in the afternoon I tried a new cable for my autoguiding from the starshoot autoguider (SSAG) into a meade lx600 via the autoguider port. This worked great. I could move the lx600 happily with the manual guide keys in PHD2 tools. This was via the on camera guiding and ST4 cable. I was very careful to check the cable was wired the same as the previous cable I had been using before it started to fail intermittently (per an error in PHD2 about checking the cable). Given that, with the new cable, all seemed well I assumed there had indeed been a cable issue.
In case this is confusing the reason I was doing this was I wanted to try a drift align on my lx600 (& x-wedge) with the PHD2 program which is just great for it.
I packed up and then fiddled around with the computer waiting for sunset including installing some software like cartes du ciel and stellarium with the intent of trying them that evening. I think I may have also upgraded PHD2 to 2.6.8 at that time but am not totally sure. Then I went up to use the scope and couldn’t move the scope to guide even with manual guide keys. PHD2 was still definitely connecting to the SSAG guidescope as the image was coming through.
I have now spent 4 days slightly freaking about whether I have broken something. Typically I use my lx600 for visual observing and have just started astrophotography and have an lx85 with 70mm APO for that. This has been working awesomely with PHD2 and on camera guiding until I had the cable errors mentioned above. I have now run a cycle of approaches to try and understand the problem:
- I have tried PHD 2.6.6, 2.6.7 and 2.6.8 with the same results (2.6.8 throws an error saying Pulseguide has failed when I try manual guide)
- I have swapped out multiple cables to no avail
- I have tried an SSAG and a ZWO mini for oncamera guiding no dice
- I have tried these all with both the lx85 and lx600 for oncamera guiding through the guide ports
- I have also tried them on my work laptop and personal laptop so that I have seen if the laptop has anything to do with this.
So I then moved to trying ASCOM guiding through the RS232 port. I used my #507 cable for the lx600 with stella and a serial to USB connector to connect to my laptop. No success with PHD2. ASCOM diagnostics with various of the meade drivers did connect successfully to the telescope. I was also able to in fact move the telescope using the old autostar suite from meade. The cable also happily connected to the starlock system. (I was at the point of screaming when this suddenly went right so that was a lovely moment ). I also managed to move it with cartes du ciel. Sometimes this crashed and I had to restart everything to get the connection to the telescope to work
This all made me relax about having smoked the telescope electronics somehow .
One strange thing showing up in PHD2 is that when I press to manual guide in the bottom right it comes up saying “5000ms, 0.0px” (with an arrow in whatever direction I decided to guide). The 0.0px seems odd I don’t know if it should be saying that or I have a setting wrong somewhere so it isn’t guiding.
I was wondering:
- Has anyone else run into issues like this?
- Do you have any suggestions about how I could debug this further.
- Do you have any suggestions on if there is anywhere good to call for customer support/help.
- Is there a problem where I just need to RTFM (please let this be true)
I am a newby to this forum and to astrophotography and super embarrassed posting like this for the first time. I got super excited when my lx85 as a starter setup worked really well on orion and got me an image I was really happy with in March. I was hoping to use the lx600 to have a crack at taking pictures of galaxies, not just looking at planets but this is really disappointing. Any help would be appreciated… I have read a lot of previous posts here including (https://www.cloudyni.../#entry10112678) which seemed similar and mpsron was kind to message with me but unfortunately the actions that helped him didn’t fix my situation.
Really sorry if this is too basic, not described well enough or the questions I am asking aren't clear. Just getting started in AP from having enjoyed visual observing.
