Sunspots, Your daily science lesson!

I need a lesson on getting the focus figured out. I never have good luck photographing the sun. I think I'll try a few more before the sun goes down.
Anyway, Sunspot 693 is about the size of Jupiter and Sunspot 696 is getting bigger. If you are not familar with the sun, sunspots are cooler areas on the surface of the sun. Solar flare erupt from areas above those spots.
Slightly better shot?

With one of these filters on the telescope:
I still need to get the focus down.
I guess its not as simple as "focus at infinity" when looking through a telescope? Also, how long (or short) a shutter speed do you use? I'm wondering if part of the problem is the fact the sun is in constant motion across the sky.
One thing I has always wondered. What is the "depth of field" when looking through a telescope? I mean, if you focus on a star that is 20 light years away, will a background star 1,000 light years away still be in focus?

Excellent images of sunspots - impressive.
Would you please take a moment to explain to your readers the filters you are using to protect your eyes and your camera from solar destruction? I know you are aware of the danger of solar shooting with telescopes, but all of your readers may not be as knowledgeable - so please -
DO NOT LOOK AT THE SUN WITH A TELESCOPE WITHOUT APPROPRIATE FILTERS. SMOKED GLASS WON'T WORK FOR A TRUE TELESCOPE.

and a 90mm(?) S-C. I didn't know they sold adapters for telescope mounting for the C series Olympus, but I just found a web site for the Digi-T, very cool! I've got an old 8 inch newtonian and C90-ETX that I'd like to shoot with digital but figured I'd have to use the afocal method with my C740, guess I should have figured someone would have made some adapters, interesting. Thanks for the info on the attachments.
I did try some afocal shots with my spotting scope a while back, came out better than I thought it would.

First, get the scope setup and ready, remove the eyepiece and insert the
camera. If you can, disable AF and manually focus the camera.
Also, there are a couple of different kinds of filters. The one in your
kit is glass. I have a different material that's almost flexible--I am
concerned that it will be damaged and I will not know until I look through
the 'scope.
I have a Celestron 8" SC. I have T-rings for my SLR but prefer to shoot
with an CoolPix 950 because I don't think the Celestron can swing the
weight of the SLR with the motor drive.

P.S. I hope that those not familar with the subject will take a moment to
understand that using a camera lens (or even just your eyes) or telescope
to shoot pictures of the sun requires specialized filters and failing to use
them may result in damage to your eyes. Upto and including blindness.
You should NEVER point a camera or telescope at the sun unless it is
properly equipped with solar filters.
When your scope is properly equipped, you should NEVER leave it pointed
at the sun while it is unattended lest someone think the solar filter is a lens
cover...
