M51 revisited

[Trevor N]

Managed to get some more mono data for this image and I believe this has improved the detail. It was taken through a celestron 9.25 with f6.3 reducer. I used an atik 314L. About 90 mins mono and 45 mins colour. Regards , Trevor

Now that image is very nice

Well done

[Jarvo]

Nice image. Forgive what may be a daft question but is the image cropped or is that the size the galaxy appears on the CCD?

Great image

[SlipperySquid]

Have you used any noise reduction or blur on the image? I think you've overdone it and washed out some of the galaxy detail? There is detail there to be seen and a little bit of noise in the image and greater detail in the galaxy is a better trade off I think?

Matt.

Lovely clean image there Trevor

[AndyUK]

That's seriously deep... (I'm assuming that this is full frame...?)

[RogerTheDodger]

Trev, wn was this taken? SN2011dh looks a bit dim//non-existent.

Hi Roger,

I think this is were sn2011dh was.

i did m51 with a 8" sct with a 6.3 reducer on and it does fill the frame, well it did on my meade dsi pro anyway.

fantastic image and i like the colours

Thanks for the comments. This is a full frame image using the f6.3 reducer on the c9.25. I have used noise reduction in the surrounding area but not much on the galaxy itself. I agree its always a trade off with detail and noise reduction. I've always imaged with shorter focus refractors before and found the guiding more difficult and of course atmospherics more noticeable. Like everything else in life its all about trying to get the balance right. All good fun though. Most of the data was captured before the recent nova. Regards , Trevor
