Hope this is the right place to ask about the Coronado PST
i recently acquired this scope and I can’t get any surface details to show on the sun, I have played with the tuning ring but apart from being able to see some flares on the rim of the sun, no surface details came through. I was using my own 8mm and 11mm Explore
what I saw was just a red blob, pretty much like white light viewing with a red filter. Turning the tuning ring only changed the intensity of the light coming through
is this what is expected of the PST? Or do you think I am doing something wrong or my PST may well be faulty?
Hello folks, I’ve decided to sell some of the items I don’t use.
Also, I moved over from a Herschel Wedge to the 82mm IDAS UHB-RS white light filter so my Baader SC and ND filters and small IDAS filters are for sale.
I’ll be in Edinburgh for a few days from 28th Feb then in Guildford for a few days from 6th March and can post from either location or meet up if you’d like to inspect first.

Really really struggled to get this working in photoshop. I think I've screwed up the exposure on the prom capture so the disc ended up being a fair size larger than the surface detail which was always going to give me a bit of a halo around the image. Hope its not too bad but comments and advice are always welcome
Taken with the Coronado Solarmax SS60 and PGR Grasshopper today, 700 frames proms, 1000 surface. Not much happening today when I took this which is a shame because I've just seen some cracking pictures of looping proms from yesterday!
Clear skies all
I was reading another post about modding out a PST to attach to a larger aperture scope, See here. And it got me thinking...has anyone replaced the focuser on a Coronado Solarmax 60? I find the focuser very difficult to handle, especially when imaging. Has anyone done this? Is it at all possible?
