I'm very embarrassed about this - after telling Jim and Fay to be careful not to burn out the centre of M13, guesss what I went and did?  I'll have to take some more subs at home, some time, to repair the damage.

Anyway here it is, from Saturday night. I started imaging at 1am after spending the evening showing Joe Public the delights of the sky.

Details: 18 x 5minutes.  Modified Canon 350D on Celestron C11 with F6.3 focal reducer.  No filters.

As usual, a great image, fantastic M13, Mark. It is cropped?

Hi Mark, It's interesting how different it looks to mine. with a larger aperture and longer exposure are you picking up fainter stars so that the burnt out core is actually all you see in mine? according to the book M13 is 145 lyrs across so I wonder at what point they measure that. anyway it's a lovely pic.

Looks good Mark - I am liking the star colours in this image. You also have the 'propellor' bit showing that I identified in my last attempt at m13...

Nice one - John

The Thing

Lovely image, If you think that's a burnt out core wait 'til I post mine! The resolution is excellent, as are the colours. What did you process it in?

That's really great image Mark, the colours look really good.  Was this at F/6.3 or f/10 ?


MarkS

Thanks for your comments.

Jim - It should be possible to match your stars against mine to see which area your image covers

Fay - I have binned this to half size and then cropped off the edges where the bad coma is

Dunc - I do all my processing in IRIS.  I haven't even applied a deconvolution to this

Robert - It was F6.3
