More repocessed material
M82 with H-alpha light to show massive outburst of hydrogen gasfrom galaxy core.
Details in original post.
IC1848 (Part of the Soul nebula) in H-alpha light + RGB data trough UHC-s filter.
Details in original post.
M106, details in original post.

California Nebula Reprocessed
This version is combined from two images of the same target.Images are taken with different optical configurations. First was taken with SW 80ED refractor and second with Canon EF 200mm f2.8 camera lens.
CCDstack software was used to combine those two images and here is the result.

Reprocessed material from winter 2007-08
Here in northern Finland we have now a mandatory pause for astro imaging doe the high latitude.
Now is good time to reorganize image archives and improve processing skils.
Few new images was found from my HD, like material for M45 image.
I just place images here with they name. Imaging details can be found from original posts.
All the images are taken with QHY8 camera trough various optical conficurations.
Note! Some fo the images are in high resolution.
Klick for the large image.

M106, update
Now it's over here, nights are not astronomically dark anymore.
-
I managed to shoot 18.04. three more hours for M106.
The outer halo is now somehow more visble but massive light pollution, in my
location, eats out lots of it, IDAS LP filter helpped though..
_
I used longer subs, 1200s, for this secon tryout.
9 x 1200s = 3h
-
There is older subs, 8x900s from 17.04, combined to this new image,
so there is 5h total exposure time used.
-
Same setup, than in previous post.
-
I'm very pleased to functionality of SXV-AO active optics unit.
Becouset of AO, many details can be seen in the core of the M106 galaxy.
Processing was difficult doe the gradients coused by LP.
There is some deconvolution and wavelets used in processing
to bring out details more cleary.
