Well done for getting a photo of the sun. The sharp limb suggests the image is in focus, but I'm not sure what the dark spot is. There isn't a big spot like that on the sun at the moment, so it is probably something on your optics. :( The much smaller spots on the far left are probably genuine solar features. (I would guess the group designated AR2541) There is a biggish spot just appeared today on the left hand limb of the sun, and it might be worth trying to getting photo of that - especially since the weather has now improved.

I look forward to seeing your next photo.

Its a shame because the spot on that photo is the new spot which I mentioned earlier! It is called AR2542, and is the same spot that I have photographed previously coming back around the limb for a second appearance!

Try to get that one again, but work on the focusing. Getting a sharp limb is often the best place to start. Since you are taking single shots you might have to take 20 or more to eventually get a one with a sharp focus. At some point you might want to consider taking a video file of hundreds of frames and then stacking the best.

Many people do 'colourise' their sun pictures. I've tended to avoid that myself, but I admit they look impressive. :)

Hi Aratus thanks for the reply I will try again but was quite hard as the laptop screen was too bright with sun,so I wil try to make my screen darker by covering so I can get better focus of the limb again.I am quite pleased with the colour image as it shows of the flares at the edge.

What I used to do is put the laptop in a cardboard box big enough to get my head in (no comments! :) ) I then fixed a thick blanket over the top. Then by putting my head in the box, under the blanket, it was dark enough to see the screen. I then put the box on a table next to the telescope and was able to change the focus blindly while under the blanket. Theoretically at least. What often happened was that I couldn't find the focussing knob, or I ended up knocking the telescope! It worked often enough to get some decent images though. Having a remote motorised focuser will help. (It also got pretty hot under there.)

I've been getting my "Mak" on the Sun a bit more this year.

Andrew, your first Sun photo is a million times better than my first attempt.

I'm hoping to get some webcam close-ups of the Sun but haven't done any this year.
How can I be one with the universe when we don't know what 96% of it is.

Hi thanks for the reply I hope to get my shots of the sun as I was out last night for a few hours taking some more images of the planets.
