Sunspot today

I thought I would have a crack at the sun.

I cant for the life of me, get focus perfect on anything, day or night.

Grrr.... I think its the scope. It has to be. I've done everything right (I think) but still it eludes me.

Ah well, perseverance

Nice go though, Baz. Try dropping your gain and slowing your exposure rate and see how you go. I gather you are using a ToUcam and K3CCDTools? Also what is your brightness level?

Don't know what sort of conditions you've been imaging in, Baz, but anything less than fair-good seeing will make it very hard for you to achieve a sharp focus.

Tube currents, mirror temps etc will also make life just that little bit harder.

Keep at it, mate

And keep an eye on the jetstream maps and latest synoptic charts

Sorry guys, I have not gotten used to the format of putting image details in the posts. The image was a 1/125 sec at ISO 800. Prime focus through a C11
No processing.

You out there tonight?

Have a go at Jupiter. Conditions are a little better tonight

Ahhh DSLR. Thought it might have been a webcam shot.

I'd suggest you also try using the Mirror Lockup function on your DSLR Baz.
This will help keep the image sharp by minimising mirror slap.

Oh. DSLR.

Ignore what I said before

I'm gonna head out to the obs now and have another go.
