Messier 13 through the Hyperstar

[Mike Hawtin]

Yes, yet another M13, this one is a HDR image, 3.7 hours LRGB comprising 12 each 30 sec, 120 sec and 240 sec Luminance and 12 x 240 sec RG and B through a 6" Hyperstar and 428EX mono.  I'm pretty pleased with the way this one turned out but it's far from perfect, as always I'd welcome advice and constructive crticism.

Hope you like it.

Very nice result. Loads of detail down to the core of the cluster. Like all the small fuzzies in the background. Others much better versed in DSO imaging are probably in a better position to find room for any improvement

your too critical,

i think it`s a lovely image, well done

[perfrej]

It is excellent!

I am curious; how have you routed the cables?

/p

[Mike Hawtin]

Cheers Chaps.  Per, a picture is worth a thousand words.  You will have to look past the materials and workmanship, I don't have a workshop and only have hand tools.

Very impressive, great colors and very sharp.

That's a very good image, well processed and full of data. As well as Messier 13 I counted 13 background galaxies in the same field.

Using Fast Star. How did you take RGB frames?

Nice M13 !

[steppenwolf]

I really like this image - colourful and detailed.

[Paul M]

My only thoughts are: "Wow!"

I'm loving this M13 season we're having on SGL just now

[PhotoGav]

Spectacular, very well done, love it! The variety of colours in there is beautiful. I also love the pic of your set up, it is wonderfully Heath Robinson, but wow it works!

The framing and field of view is lovely, what focal length is that?

Not sure if it's me, my screen (I'm looking on an ipad) or what, but is the background quite grainy / noisy?

Wonderful image Mike, you have the hyperstar beautifully tuned ...

Great processing , lovely colour..

[Mike Hawtin]

Thank you all very much for your kind comments.

PaulB, one of the spacer/adapters is internally threaded for 1.25" filters, change over is reasonably quick and painless.

Gav, the RGB stack had more background noise than I would like so I dialled the background of the LRGB combination back with Curves Transformation in PI, perhaps it needed a bit more but it looks ok on my monitor.  The focal length is 290 mm.   Had to smile at your Heath Robinson comment, as I had saved that pic as "Heath Robinson lives".

Absolutely stunning image. Easily the best M13 I have seen. The fact that there are numerous galaxies in the image as well is just jaw dropping.

Well done!

[Mike Hawtin]

Wow, cheers Droogie, I must say I'm a bit chuffed with how it turned out as I really didn't expect too much from that subject.

Mike.
