Dear al(L)
Somewhat hazy but clear sky this morning when my wife & me travelled up on the Pennines where the hills were quite cloudy & misty. Stopped at one misted out view-point, where there was a "tribute" site consisting of flowers & teddy bears, obviously related to some recent road accident victims. (such Tributes are Not to my taste - I'm afraid). Who should then arrive but a couple of car loads of people adding new flowers. We journeyed on to another favourite Pennine location, passing a big load of fly tipping. The only consolation when we got to our last view-point for another brew was seeing a fantastic hunting bird which dived down and landed less than ten yards from us.
Back home early afternoon (& blue sky) I visually observed & imaged the Sun. Nice surprised to visually observe two obvious though small Sunspots.
Two images,one White Light showing 2No Sunspots, the other Ha revealing super-granulations & small bright-ish plage.
Best wishes from Cliff

What camera ?

The camera I use for imaging the Sun, both in White Light used with 88mm f5 refractor or Ha using a 60mm Coronado Ha SolarMax scope is a Opticstar PL-131m (meaning monochrome Video camera) . I always use the same gear for Solar imaging and I usually state this on my images. I chose the Opticstar PL-131m because it was cheap but more importantly had a relatively large sensor (able to encompass the whole Sun disc using my 88mm refractor or SolarMax 60mm). I initially used that gear on a driven mount outdoors in our back garden. But unfortunately developed arthritis, which amongst other things stopped me night sky observing. However, I then found that I could use my Opticstar PL-131m video camera on an ordinary but sturdy photo tripod with pan & tilt head, getting 20 second video clips and keep the Sun contained on the PL-131m sensor with the camera fixed on the tripod. Although it is necessary to realign the camera frequently! So I now do 95% of my Sun imaging through our west facing back bedroom window.
I stack the 20second video clips using Registax version 5.
Best of luck from Cliff
PS -The PL-231m video camera is only CMOS not a CCD which is one reason it is fairly cheap. I think I paid £175 for it about 9 years ago & they still cost about the same.
If you want to get Upper-class Pictures you probably want a better camera, But the tackle serves my requirements pretty well.

Thanks for your comment.
Although it might be a bit over the top !!!
My Sun images are pretty ordinary really. I use mostly relatively cheap equipment. That said my My Coranado Ha SolarMax 60mm was pretty expensive - although I got it cheapish because it was "shop-soiled". My refractor was reasonably priced for a decent 88mm f5. It was ironic though when I bought the refractor. The seller (an expert Deep Sky imager himself) query my intervention to buy such a short focus scope. Ironically he was trying to do me a nice favour, but when I was forced to drop Night Sky observing / imaging a few years later, I found the short focal ratio ideal for imaging the Sun with my Opticstar camera. However, I think my Opticstar video camera with big sensor although only CMOS was quite cheap.
Best of luck from Cliff
