[David Smith]

Set the alarm early this morning as the forecast looked good last night and I was rewarded not only with clear skies but good seeing also.

When I first plugged in the camera to take the white lights, the faculae on the west limb was so bright it was almost like looking at an H alpha filament!

Great set of images there.

[Dave Smith]

Great images David. I admire your devotion. It looks as if you need a tilt adapter for your Ha images.

Dave, to be fair I completely fanned on capturing flats yesterday. When I remember to do this it pretty much eliminates the Newton rings. I also need to get a decent 3x barlow so that I can do flats properly. With my current set up (2x or 2.25x, I did try using one as an extension tube for the other but could not reach focus) I have all sorts of problems with trying to get full chip illumination for my flats which then leads to a bit of a processing nightmare! All in good time though.

Excellent images David, really must make an effort to get up earlier, trouble is clear days and nights tend to coincide, been trying to catch Pluto which I can't see until about 1.30am so not getting to bed until 2.30am.

I find flats a bit hit and miss, tried defocussed / bag / cling film at different histo levels, sometimes they work perfectly other times not, doesn't help not having a clue what I'm doing

Yep, I get the same issue Dave. Have tried adjusting my flats with levels in GIMP which sometimes works.
