2nd try at Capella, 27 min total exposure

[Jannis]

Capella was only a star i thought of as a nice star to focuse on, as it's very bright. but after working a bit on mt single 6 min sub of capella, i could see it was a lot more to it then a single bright star and darkness.

But, after not being pleased with my single 6 min exposure of capella for anything but focuse, i decided to see if it was possible to get more out of it, and it surely was.

I gave it a try, and stacked 51x 30sec frames, bu8t unfortunally couldn't do dark, flat and so on, as my DSLR shutter froze, and camera broke down and refused to take any more pics. Well, no wonder as mirror wouldn't more due to iceing.. lol.

Here's my first 6 min pic after processed in PS (full res):

And then here's the all new 27 min worth of data (full res):

Edit: i'm sorry, i posted this in teh observing section, should have been in teh imaging section. Can a mod please move this thread?

Super images!

Why do you see the light spectrum in those images? Very nice btw.

Lovely image, well done for staying out with the ice and getting the final product!

It is worth a bit of exposure time when you see it like this!

Well done and thanks for sharing!

Nice image and great idea, Capella deep field

[Pete Presland]

nice diffraction spikes!

[Jannis]

Thanks for feedback guys!

Hope i will be able to have another go at this at a later time also with the possebility to add darks and flats, and preferably with a coma corrector.

Edit: Oh yeah, and without the full moon! haha

Do you mean in the diffraction spikes?

Nice work....it's unusual to see an image of one of the brighter stars set into a deep field....it looks great

Cheers

Exactly how much of a difference would a coma corrector do to an image like this then?

[Jannis]

I've been wondering that myself. And after playing with the lens correction tools in PS, i still can't get a good picture out of it, so I've given up on that and understood that unfortunately this can't be corrected in PS afterward with a good result.

I will order a coma corrector one day, but i probably can't afford it all before in the fall, so will be a while until i can give an update. Unless maybe someone else who have a coma corrector and a similar scope could give it a try to compare the pics?

But for sure, when i Do get one, and a LP filter, i will be sure to give this another try, at a much longer exposure.

Yes the diffraction spikes, they look different to all the other images I have seen. Why can you see the light spectrum in them?

[RikM]

Lovely pictures. There is something magical about bright stars with nice diffraction spikes and you have caught loads of colour as well. Well done.

[Deneb]

I think thats a wonderful shot of Capella, I do have something for diffraction spikes.
