Interesting, Ed. I’d love to learn more. Is this intended for general use by AAVSO members? What range of stellar magnitudes will the S30 Pro be capable of measuring reliable brightness? It requires a Pi 5 and two 256mb USB sticks? Anything else?

Excellent Ed,
Is the GPS USB the “HiLetgo VK172 G-Mouse USB GPS/GLONASS USB GPS Receiver” available on Amazon for $12?

Interesting. I have a DWARF3 spoke and I was told it could not be used for Photometry. Look at this post on my facebook group. I will have to give it a try.
Hi Ed,
a question regarding OS: Raspberrx Pi Imager offers now Trixie version of 64 bit OS. Should I install that or should I stick to Bookworm as you wrote? There are several different versions under other OS choices. If Bookworm than which one?
Bookworm Lite was choosen because of a fog-detector script.
I have tested Trixie, and it is a no go. Currently bringing it back to Bookworm. Apart from that, our friends from ZWO have closed up the Seestars with their latest updates. My aim is to see whether there are other ways to ‘plan’ the list of variables within a Seestar.
I have assembled today the hardware.
Configuration consists of:
Raspberry PI 5, 4GB
64 bit OS on micro SD 32 GB (suggested Bookworm lite)
W27480 PCIe TO 2-CH M.2 HAT+ adaptor for SSD
2 x 512 GB SSD, not yet in RAID, but will be…
First booting was succesful, so I have installed also your SeeVar.
After I have started to download charts from AAVSO. This is really slow… 
My question: what will be with charts which were not downloaded because of time out? If I will restart this procedure then will the system check if a chart is already downloaded or the process will start again from the first star?
Hey, László
I know, it is sllllooowwww. But you are asking AAVSO for charts, and we do not like to overload their systems. Anything you missed, will be tried later.
I am currently working on getting the controls via ALPACA. My S30-pro came in yesterday, and of course, the weather is not helping.
With the weather is same by me… my Seestar came one week ago, till than no sky at all 
I have opened my own topic, so the AAVSO smartgroup can use this for their progress.
Why can’t the Dwarf 3 be used for photometr? I have a Dwarf 3 and have been using the green channel for photometry.

Uhhh. well, I have not tested it on a Dwarf 3
I am testing on a Seestar S30-pro
If your scope talks alpaca, well, I think it could be used.
Barbara:
I don’t know of any reason that photometry can’t be done with the Dwarf III. We haven’t done as much measurement of the Dwarf III as the S50, but none of the tests we’ve run on Dwarf III data have raised any red flags.

This is great to hear. I also have a DWARF3 and I now can’t wait to try some photometry. I was concerned about the filter system. The dwarf2 takes normal scope filters that can be screwed onto a magnetic filter holder. The DWARF3 has internal filters you select in the software. How are you managing the filters?
For photometry you would use the internal IR filter. No external filters. For photometry you would separate the fits image into RGB. I do photometry only on the G image
