Re: Pier Crash - need help diagnosing

I remotely updated things and I'll do that check later today when I'm out in the OBS. But I was a bit reluctant to do anything until I had a confirmation that I did things right. :)

It worked for me. Just manually slew to 5 degrees past meridian and see for yourself.

I'm finally getting around to updating the CP4 to firmware AP-CP4-vcpx-p02-08. I used the USB utility and all went well. I would like to turn on the limit at 5 degrees past meridian. In the Terminal tab of the USB utility I typed in :LR2# and hit send. The only response I got back was "1". Did it upload correctly? joel

Re: High RMS values with PHD2
Did no know I did that! Navigating all these forums can be difficult. Its not always that easy to post a message.
Here is the link from last night. There was one episode again when the mount went awry. I also was not able to calibrate with the OAG at native focal length on the Planewave, but that is another issue. I wound up using a guide scope https://openphdguiding.org/logs/dl/PHD2_logs_Ryge.zip

Geoff,
That is really a beauty and the target is now on my hit parade. As soon as the moon gets out of the way, it will be my early evening target. You did a wonderful job, and thanks for bringing it to my attention. Dr. Henning: Go Gators! 1984 BSCE.

That’s a beautiful galaxy group. I love the details in your picture. I wonder if one can visually detect more than the two bright galaxies. Best wishes, Richard — Richard G.

Re: High RMS values with PHD2
Hi Peter It looks to me like maybe your mount was slipping in alt? there appeared to be substantial polar misalignment in your setup looking at your "before runs" that were working, you can see most of the corrections are in one direction ie polar alignment is off: pier side east pier side west then your guidestar degraded and was lost Also during your many attempts at calibration, DEC did not appear to be responsive, maybe a bad cable there? even after a successful recalibration, your PA looked still substantially off. in the second guidelog things seemed better you might do a guiding assistant run after your calibration and measure polar alignment, as well as get other recommendations for your guiding settings? you only need 2-3 minutes for that.

I do not know about the 600, but A-P recommends a separate power supply for their recent mounts. Bryan

This is a nice little group which, rather surprisingly, is not often imaged. While the galaxies are not big, they still reveal some detail.

Re: Bad initial guiding on my AP600e
Tom Blahovici
I guess it doesn't help that the temperature was at -10C. Seems to get worse as the temperature goes lower. Last night it was only one exposure where I had this issue. Last week, when the temperature was -15 I had quite a few more.
Is it possible the power supply contributed? I have a powerwerx 30 amp switching supply but I power the whole imaging setup with it. This includes a ASI6200, ASI290, Moonlight Nitecrawler and a dew heater. Tom

Re: Bad initial guiding on my AP600e
I used this mount when I was getting started in AP. I have since upgraded to a newer AP mount
This mount has significant stiction on the DEC axis. This appears as backlash when you calibrate with PhD or any other software. But this isn't backlash in the true sense of the term. This mount uses plane bearings on the DEC axis that are quite sufficient for the payload but unfortunately suffers from stiction. The mount will not move over several commands and then suddenly take off. It has overcompensated now and will again have to be guided back. And then it goes on oscillating. RA guiding is usually awesome but DEC guiding is a disaster. I do not know a good solution to the stiction issue, maybe a light lubricant on the DEC axis rather than a heavy one may help but it may introduce other issues. But there is a very easy workaround: Dont polar align too precisely. Set phD to guide in only one direction on the DEC axis. When it is moving in only one direction, there is very little stiction. You will see your problems go away.

Here is the link for the log. I see you also post on PHD. To tell you the truth, I had to mark notifications from that forum as spam, because they were coming through constantly, and I was unable to reset the notification. In any case somehow I got things back to normal last night, but I am not sure what caused the problem, and what fixed it.

Re: Bad initial guiding on my AP600e
Roland Christen
Adding simple backlash compensation is not something I recommend. It can very easily cause system instability in Dec. PHD2 has a new adaptive compensation that might work well, but you would need to go to their user group to find out if this fits your needs. If your guiding is good then i would leave it be.

A follow up on dec backlash. So, I should be allowing PHD to measure backlash and then applying it accordingly? I thought the recommendation was not to do that. Even without it, I have excellent tracking. Thanks

It will be a sticker on the right side, unless it is an early CP3, which may not have one. It will be GTOCP3-xxxx.
