Astrophotography / Another M51

« Last post by MarkS on Today at 01:09:54 »

M51, the Whirlpool Galaxy is one of my all time favourites.

This one was taken last week Thursday 19 April as part of an experiment with a new setup:  Sony A7S on Celestron C11 with Starizona 0.72x large format corrector.

This is 240x30sec at ISO 10000 i.e. 2 hours total exposure:

I think I meant I liked the penultimate one best - this one:

Astrophotography / Re: M 16 in narrowband

Many thanks Mark.  I wasn't sure about the brown colour, but that's how it comes out with Hubble palette, either that or yellow or orange, neither of which appealed.

But overall pretty pleased with it, especially as it was a last minute decision to take it when M81 images started trailing.

Lol, to be honest Mark, I could not get rid of the blue in the galaxy, and in the end went on line and found many other images came out blue, so I just went with it.

I do like colour though.  You will notice I rarely post mono images, they just feel unfinished to me.

Thanks very much Mark. 

I must say I find narrowband much easier to do, but as I can do very little broadband from home, I probably get more practice with it.  I can't even do some of the narrowband targets from home.

Thanks Mark, I posted my revision before I saw your reply.

Well I have reliably been informed that this is indeed IFN I am seeing, and so following a bit of a tutorial on how to stretch this further, I am posting a further version of the image:

It's probably a bit noisy now and needs further data, but was pleased to get it.

Another fine image Carole and processed very nicely.

I do think that your narrowband images are getting better and better each time.

This one and M16 are the two best images from the Cairds trip, with M81/82 coming closely behind.

I love M81 and you've got some good data there.

For my taste me it's a bit too much of the "Robert Gendler" style of processing i.e. if you captured any colour then flaunt it!
