I haven't uploaded anything for a while and thought I would try something a little different.
Here is a photo of the Sun showing a small sun spot group.
Just at the moment we are at the minimum of the 11 year solar cycle, so there are very few spots to be seen on the Suns surface.
The camera was mounted onto the telescope using a T2 mount.
A home made solar filter was used on the objective lens.
The filter is made from Baader Astro Solar Film which cuts out 99.9% of the light and heat reaching the camera.
The scope has a focal length of 350mm and an aperture of f5.
Shutter speed was 1/1600 sec
Cropped from the original image to 990 x 990 pixels to allow for a 10 pixel white border.
Colour, Brightness, and Contrast adjusted to give a nice shade of yellow.
A little USM to finish.
Hope you enjoy it, and as always comments are welcomed.

I'm glad I opened this, as a thumbnail I thought it was somebody having a bit of a joke
Are those dots that look like dust the sun spots?
Amazing what you can learn here.

Not something you see every day - or at least not that close! As you say; it looks very quiet at the moment.
I was amazed that it was a direct image rather than reflected. The only time I've looked at sun spots was the old telescope and cardboard routine - clumsy but safe. Nice one!
The Baader Astro Solar film is very good.
Mind you it ought to be at the price.
It costs £25 for a piece of film A4 size.
I've made a filter for the telescope, two small filters for my binoculars, and I still have a little bit left in case I manage to puncture one of the ones I have made.
It's the first time I have had the 300D hooked up to the scope, so I'm pleased with the result.
Just need to perfect the focusing I think.
Thanks for your interest.

It also appears to be pulsing to me (must have the same monitor)
Different and well done
Pretty cool image Doug, would be interested to see if you could get a half decent one of Saturn
