With a bit of solar activity and inspired by the excellent images posted earlier today , I thought it about time to point the Ha scope at the sun. As is always the case, just as I'd set up a strong southerly change blew through. Well at least it knocked the temperature down a bit.
Imaged with the 40 km/hr southerly buffeting the scope and mount but have nowhere to get out of that wind direction.
Set up is an PST conversion operating at 85mm F 10.6 on an EQ5 mount, camera ZWO290mc , best 200 of 2000 frames .

Nice capture Jeff, thanks for sharing. Any images of your modded PST?

[Saturnine (Jeff)]

Thanks Ivan
As requested, a picture of the PST modded scope. It is an 4" (102mm) f9 Jaegers lens from Surplus Shed that I had assembled about 10 years ago. The Jaegers lens had a good reputation for quality optics. ERF is an 90mm Baader ( should have got the 110mm ) in a custom cell and a machined adapter to fit the focuser drawtube.
Pretty basic but it does the job nicely and is a step up from the 40mm PST objective.

Jeff,
Nice looking Stage 1 PST mod....
You’re picking up some good detail, but a mono camera would make your job easier.
Well done!

Thanks Ken & Ivan, feedback is appreciated.
I do have an Meade DSI mono, should check what shutter speeds it can
speed up to and if it would be suitable for solar Ha imaging, though I'm happy enough using the 290mc, not necessarily after research grade images.

Beatiful I love it.

Thanks Alex, do you mean the image or the scope.

That’s a neat pic. Something so intriguing about the sun.
Look forward to more of these.
