Well I deleted my normal sized three moon directory, thinking it was one of the poorer raw runs. Bugga. Anyway I am very happy with the extension tube setup.
I have processed with a CRT monitor next to my lcd, so I can get it to look right.
I align the colours after the astral image split on the moon, and the planet does not look spot on. But at the same time, seeing wasn't super and so there is some blue spread. I have reduced the gamma, but it could do with a further reduction???
1/50th exposure, 50% gamma, 50% gain with slight loss due to the extension tube, I may go for 1/33 exposure next time.
My best to date. I have split the video and will do that process and then compare.
This is actual size, no resampling, just making use of the 5x powermate's ability to range from 5x to 7.7x by using an extension tube.
Love the image scale, it's huge! 630 frames is a lot to stack! Especially if the seeing wasn't 8/10 or above.
Can you try stacking less?
What i've been doing lately, is when I create the reference frame, I process the reference frame a lot harder (4->15, 3->10), and then after optimise, I find it really does a better job of ranking the best quality first, so in the stack page I drag down to about 100 and stack that. It comes out a lot sharper than stacking more frames, which tended to blur the minor features a bit more.
That's a marvellous image and i'm sure it'll come out even better after you do the split jobby.
I don't know how you can image at 1/50th of a second, or even 1/33rd for that matter. Looking forward to the new 900nc to see if it's anything more sensitive than the neximage. I'd have to have gain at 100% and heaps of brightness and Gamma at 1/50th of a second and I'd still be underexposed (say <150).
Very nice mate! Gotta be happy with that. That extension tube has done the trick. I also use one as you know but I figured I was losing too much from it & halved its length which seems to be spot on for the F8 refractor.
Can't wait to try an extension tube myself.. although it's just asking for more pain in my case.. my EQ platform requires constant attention to keep the planet in the field of view as it is.. a bigger planet is going to mean more pain! Plus, it's hard enough avoiding dust motes as it is..
will give this a rip, I will shoot the extension tube up to you tomorrow to try, then will see if mogg can build, or if bintel have any more of these floating around.
Incidentally there was no way known I could image at 1/25th or even 1/33rd this morning, zreo gamma zero gain was miles too bright. I went with 1/50th.
There are other factors at work here other than just clouds regarding transparency. Normally I would have to up it to 1/25th or 1/33rd but this morning was the exception to the rule. I don't get much of that really thin cloud here, its either full-on or not at all.
This morning I was also getting the halo around the planet, & it seems to vary in colour from night to night when it IS present. I'm thinking dust & moisture, & varying degrees of both. Interesting!
What extension tube are you talking about? I have a lot of old bits(Edit OK not just on me).For one a 1 1/4 eyepiece projection tube with T threads. At rear (M)and front (F) you are welcome to.
