Yep, that was with the 5x powermate. I'm currently processing an image with 50% bigger scale, that was taken with the 5x and a couple of extension tubes.. having a little trouble, but I'll sort it out!
One more with the 5x, this was a test avi taken earlier in the night just to test the settings/histogram etc.. turned out rather well..
The next one was with the 5x and 8cm extension tube, giving a rather massive image, with moderately good detail, but I dont know what the go is with that line on the planets edge... ??? (insert your suggestions here!!)
Cheers for the comments guys.. I must say I'm rather impressed with myself.
I have no idea about that line on the larger image, I assume it isn't in your capture video at all. Where abouts in your processing does it first appear?
The line becomes apparent after stacking. the more I process, the worse it gets... I've noticed however, the edge with the line gets VERY close to the edge of the FOV (parallel with the line) for about 300 of the 700 frame AVI...
I'll re-process it later, but delete any frame where its close to the edge... Mind you, that avi, jup only has maybe 30px either side of it... just squeezes into the FOV
I might add, I finally took the advice about getting a UV/IR filter for the webcam... These images and yesterdays HORRIBLE image were the first taken with the Baader UV/IR block in place... It sure does make focusing easier...
That is an awesome result for an 8 inch scope.
The line you are getting is almost definately because one of
the frames in your stack went near or touched the edge of the
FOV. I get them quite often.
Quite a good feeling isn't it to keep getting your personal best
change in a few nights ?
I'm glad you took the advice to get the IR filter.
Focusing is sooooo much easier.
thanks guys. Oggie, i still think i can get more out of it, the seeing was above average but still far from perfect. I think however these shots show the potential of an 8 inch rather well.. Just imagine if the seeing was perfect, the collimation was spot on (which it wasnt) and i was using something better than a web cam ie. A dmk or dbk. There's no doubting that an 8 inch is up to the task of planetary imaging. Not in my mind.
