M57 & M13- 3rd June 2010

30x10sec per colour. Plus 10x10sec darks.
Just messing about, it's too light to do anything serious!

M13 40x10sec no filters.

M27 & M57 - 25th July 2009

30 x 30second @800ISO, C9.25, prime focus.

45 x 30second @800ISO, C9.25, prime focus.

M57 24th July 2008

20 x 2min Frames.

M57 taken through guider scope.

Here's an interesting one. It's not supposed to be clear tonight, but it is so I thought I'd practice with guidescope setups and alike. This time I used the C9.25 as the guidescope and my guidescope lens as the capturing device. Here is 7 x 65 second frames from the DMK camera trained on M57. Processed in Registax, no flats, darks or bias.

Wide enough field for ya?

Time to batten down the hatches... we're supposed to be getting 40mm of rain tonight :-/

Happy birthday Gemma.

Messier 57 from 10th June 2008

The famous ring nebula Messier 57 (M57, NGC 6720)
I took this a while back, I hadn't bothered to process it until now.
Didn't spend too much time on it.
A bunch of DMK 30 second exposures.

M57 re-processed using Deepsky Stacker.

What a program... and it's free!

M57 3rd August 2007

Here's M57 again using my Canon 400D and f/6.3 focal reducer... it's very small, with a bit of star-trail.

M57 LRGB image re-processed.

Here's a highly processed and enhanced version of my LRGB image.

Below is a hubble image to compare.

I know the colours aren't correct, but it's the best I can do at present ;-)

I love the two small stars in the centre, and the smaller ones in the ring at the 6 o'clock position.

The central star is 14.7-mag.

"The Ring Nebula is about 2,000 light-years from Earth and has a diameter of about one light-year. The faint speck at its center was once a star of greater mass than our own Sun. Now, near the end of its life, it has ejected its outer layers into space, and the remnant is destined to die as a tiny white dwarf star, about the size of the Earth".

M57 - Canon EOS 400D image.

Stack of 13 images.
This shot, and all of the previous DSO images were taken with a full Moon.

M57 in B&W and colour.

Here's M57 again using my DMK and this time a 6.3 Meade focal reducer.

Below in colour using LRGB filter wheel at prime focus.

Using the new DMK.

Here's first light with the DMK.
Please Note; Jupiter is not very good to view or image from the UK this year :-(

M57; a collection of 33, 8 second exposures taken with the DMK, really easy to do using the IC Capture s/w that came with the camera and processed later in Registax.

Here's a lovely Hubble view.

M57 from last night using my friend Ray Byrne's Starlight Express MX5C CCD camera.
