I got my PST back!

My Coronado PST has been languishing in its box for a couple of years because I was getting frustrated by its fuzzy performance. I got it out last week and realised that the problem was probably the little ITF filter in the eyepiece holder. So I sent off for a replacement from Beloptik in Germany, and it duly arrived a few days later.

I just tested it and, joy of joys, it's now working brilliantly and there's a gorgeous prom on the limb. Here's a quick capture. About 500 frames, just the basic PST, QHY5-II mono cam, 2x Barlow. I'm going to have to brush up on my imaging and processing skills, but it's nice to be back in the solar game. I've done a Stage 1 mod and still have all the bits, but I prefer the basic PST as a great grab and go.

Here's the offending tiny filter. Ouch, 157 Euros for a replacement, but without it the scope is just junk.

And in colour, with a bit of artistic licence!

The Maier one from the States is cheaper ( even with import Tax)   but you have to wait a few weeks for it to clear customs over there and here.

I have read that the replacement is a lot better quality than the original in terms of sealant around the edges where I think water vapour creeps in and somehow helps oxidise the surfaces.

Seeing a good result, like yours from a PST is a great advert for a scope that can be picked up for around £400.    It's not the bright sunlight that induces tears when you look at some of the prices of other 'entry-level'  solar gear.

WOW, what a comeback for the PST, superb looking Prom!
