M3 - 4-03-08 - Canon 350D

[jcm]

This is the second object I imaged last night. The Canon is pretty good at imaging globular clusters. If you concentrate on a nice tight focus and guide accurately , you can get quite a reasonable enlarged section from the image. The imaged below is cropped from the full frame. When I can get to M13 I want to try and push the Canon to its limits.

130mm APO , F6 , Canon 350D at 800 IS0.

14 X 5 mins.

Lovely image, John - some nice colour in there too.

Spot on John. Nice subtle colours and a great job on the processing again

[CELESCOPE]

Thats a corker John , nice to come back with an image so nice ,

Thanks Steve ,Martin , Rog.

I really like using the 350D and with the correct selection of targets it can produce an excellent result.

Another excellent image with spot on focus, it just goes to show what can be achieved with a DSLR.

Super result John, as are your M53 and NGC5053 images.

As you say, that 350D does capture a very nice 'glob'.

Cracking result John. GC's are my favourite DSO's, this is as good as I have seen. Keep up the good work.

Very nice glob John......

Hopefully i will have as much luck with the 350d once i get into imaging a lot more.....

Cheers

:shock: lost the words... simply astonishing

Had a go at reprocessing this image.

Tried to make the core stars clearer and to increase star colours.

Added to first post to compare.

Two superb images John, well done.

Hi,

John a very crisp clear pic. As you say the Canon does indeed look well suited to this type of object. You have given me the motivation to give it a go myself.

A great result well done

That's a couple of great pictures you've posted. There's a huge range in colour in the stars which is quite a delight to look at. I think globular clusters are great and you've certainly captured M13 well.

Really nice results John, especially the second with DDP filtering applied, something that I usually apply to my 'globs'.

Hi Dave,

I am having a go at various image processing "techniques" and also trying to reduce noise in the final image. One of the probs with the DSLR images is level of noise after processing.

John

That does make things a tad more difficult John.

There's no doubt, that the better the SNR of an image, the more aggressive you can be with the processing. without noticeable degradation.

DDP is a powerful 'tool', but it doesn't work for all objects, and has to be used with care, whatever the image.

However, experimentation is the 'name of the game', and providing you keep your original safely stored, I find its the best way to understand the effect of the various processing algoritms.

Great images, especially liked the redone one, some nice colouring coming in there.
