Hi guys.
Been too tired to stay out late or get up early for planetary in the last few days, so yesterday morning I decided to get some solar shots in before I headed out for Mothers Day shopping
Using my (
homemade) white light solar filter, the view through the eyepiece was fantastic.. ar756 is HUGE! Seeing was only "ok" as the sun was still reasonably low at 8:30am.
I took some afocal shots with the digicam, but for some reason they turned out blurry, focus was off for some reason - the eyepiece view was focused. unfortunately I didn't find out they weren't focused until this morning
Luckily I also took some ToUcam shots. While planetary imaging with a Dob is frustrating and difficult, solar imaging with a dob is even more so. Of course I can't use the finder to line up the sun like I do with a planet, to allow it to drift through the FOV.. and when the sunspots are hidden away in the middle of the disc, it's very hard finding it on the chip in the first place, and the readjusting alignment so that it drifts through to take as many frames as possible.. very frustrating.
At newt prime focus it wasn't too bad, but with the barlow in it was almost impossible, I only got one workable avi and the sunspot region is so big, I only got 30 frames to work with before it drifted out of the FOV.
Anyway enough blah here are the results:

- ~30-80 frames stacked & wavelets processed in registax
- Unsharp mask and levels adjusted in photoshop
