Re: Feb 22nd - HA and WL images

No, in the one with Newton rings I tried to use a slightly longer exposure time. Usually they disappear after processing but probably I used too few frames to stack. I tried with Alexandra suggestion of 10% but evidently they are not enough to take them out. I should came back to use 30% as usual. ...

Re: Feb 22nd - HA and WL images

It's not that difficult. Simply slightly increase the exposition time. As much as I can but without burning the "disk". That way I can have a good image for the disk surface and for the prominences as well. That way I process them together. No need to use two layers, etc. That's exactly the way I d...

Re: Baader K line filter

from what I understand (I think Mark has more info...) The Baader CaK has a bandwidth of 80A The PST CaK and the Lunt have bandwidths of 2.2A and 2.4A respectively. If this is correct, then I'd have to say that the narrower bandwidth would give better resolution in the Cak region. Spot on there Ken...

Re: Baader K line filter

How does this K Line filter with Baader solar film compare to a specific CaK PST?
Anyone taken any images using this configuration?

K-Line is pretty poop in comparison to CaK pst (IMHO).

Have a scroll through my blog, there is loads of images taken with both filters...

Re: Sun in Ha: 2012-02-20

I think the issue of how many frames to take initially and then how many to stack is actually quite complex. In poor seeing you want to capture more frames in the hope of striking it lucky with some good frames. In regards to how many of these frames you end up using, this is where it gets tricky. ...
