This morning I changed the Ethernet cable and all is well.  It was a good night to have things go kaput with the humidity being what it was/is here in AZ at the moment.  A very dewy night.

Re: Recommendation for Observatory PC

Dale Ghent
 

OnLogic ML100G-50 or ML100G-51. Intel Whiskey Lake CPU that is quite powerful for its 15W TDP. Throw 16GB of RAM and a 1TB M.2 SSD in there and you have a good system that will handily run a DSO imaging system and suck down high framerates for solar/lunar/planetary photography and lucky imaging.

It's not rack-mount but, honestly, such small systems are so low-power and capable these days. Just get a 2U rack shelf and set this on it. One note of caution about the OnLogic systems, however: they absolutely do not accept anything but 12V DC. Don't even think of trying to juice it with anything higher. It's a design flaw, in my opinion, that they do not include a VRM on the DC power input. I had a ML100G-50 and I fried it by accidentally hooking it up to a 13.8V power source... so yeah a 1.8V overvoltage toasted it. That's my only real complaint about their units considering the cheaper Intel NUCs accept 12-19V input.

ref:
https://www.onlogic.com/ml100g-50/
https://www.onlogic.com/ml100g-51/

If you *must* go with a true rackmount unit, I would suggest the E300 series systems combined with their rackmount kit from SuperMicro which sport, Xeon-D CPUs. I use these at home for my NIC driver development and testing, and they're low power for what they are and compact. They come with both M.2 NMVe and mSATA and can take up to 128GB of RAM. Way overkill for running a observatory,

ref:
https://www.supermicro.com/en/products/system/Mini-ITX/SYS-E300-8D.cfm

The basic gist is that embedded x86 CPUs are more than capable of running a Windows-based observatory software stack these days, but finding embedded x86 CPUs in rackmount form factors is rare.... the logic there being that racks live in data centers and data centers are expensive, so you would not be tossing low-power systems into those rack units. The embedded systems are more appropriate for running in non- or minimally-conditioned environments though.

Re: Recommendation for Observatory PC

 

Hi Barry

we opted for a fanless pc from onlogic.com

our remote observatory provider (Obstech) recommended fanless. you can configure it to suit your needs and budget. the build quality seems exceptional

they also included port stoppers: little rubber stoppers you put into ports that are not in use, to minimize dust and other contaminants from entry into the pc. so far it's worked like a charm

also our provider recommended backups on all power supplies fwiw

It appears that RA is oscillating quite a bit. Possible reasons:

1) wrong calibration values - highly likely
2) mount is not balanced in RA - somewhat likely

Unfortunately your graph doesn't show the guide corrections which might help determining the cause. I would run Guide Assistant, there is a lot of information generated which will help you in your settings. The RA axis should not oscillate, unless the calibration values are way wrong for that part of the sky.
