I did A-level electronice all those years ago, and the only real thing I found it useful for is 12v boat electronics. I can see next years big boat project will be a couple of solar panels.

Hi Alexandros I'm confused here. If you are trying to get an onband full disk with the 130 it is not going to happen! All the animation shows above is exactly this. There is no place you can put the disk as a whole where it onband. No amount of fiddling around, changing the spot in the fov where yo...

Welcome to the forum, Alexandras advice is sage. Given FLOs 10% summer sale, I think a DS PST would be a good buy.

Re: Full Disc June 7 in ~3nm CaK + a G-band spot detail

Nice shots Bill. Not sure you need the ERF running at native f15, it's just one more piece of glass.

Definitely be interested to see a stacked but unprocessed full disk, maybe you could upload or link to and we can have a play with the processing.
