M51 and fuzzies

Recommended Posts

Yet another attempt at the Whirlpool galaxy (M51).

This time, I decided to try to maximize detail by collecting a large quantity of Luminescence data and then applying strong deconvolution to the areas of high signal to noise.  I also decided to try out Mure denoise, a Pixinsight routine that reduces camera noise.  The final result of this LRGB processing approach is shown below and represents just over 17 hours integration time. 

I hadn't noticed before the rather strangely shaped fuzzies in the backgroud - have a look at the annotated version for IC4278 and the triangular shaped galaxy PC2292105.

This is amazing, I'm no expert but I've seen plenty of images of M51 and in my opinion this is one of the best.

Definitely a keeper! Nicely judged colours and so much detail.

Fantastic image!  What is the galaxy at the 10:30 position from NGC5195?

Very accomplished image Alan - from acquisition through to fine processing.  Tight stars, fine detail of the spiralling HII regions in the arms - top notch.  Well done.

Well, according to the free software Aladin tool, which gives you the option of searching NED (Nasa  Extragalactic Database) - it is IC4277.

Thank you, hadn't heard of Aladin before, downloading now :)

Superb, so much detail and vibrant colour, really great  to see what the Esprit 150 can do, and this is from your UK location?

Amazing detail running all the way to the core.

Thanks - :hello:

Thanks for the comment - yes the Esprit 150 is delivering the goods once more and yes, this is from my site in the UK, East Sussex.

Thanks for confirming this, there is still hope for UK imaging...

Yes indeed  :happy11: - what I think helps is that my obsey is located at quite a dark (ish) site which also seems to have relatively good seeing conditions.

      First attempt at any DSO other than the brighter stuff like M42 or Andromeda.
      Learning to use the AZ-Gti /Sharpcap polar align / windows synscan app / APT platesolving ... And guiding ! all in one night ?
      all went well so had a quick 30 mins on M51 (first time I'd ever managed to actually frame it ... Plate solving is amazing)
      90 second subs gain 420 and 5 darks and synthetic flat for dust bunnies / gradients
      Wish I'd have gone longer now as tried a 5 minute sub once guiding was working which looked good .
      Very noisy but only 30 mins .

      Hi All, once again it's been a great pleasure to share this passion with SGL friends so I'd like to say a small thanks to everyone by posting a link to some data we shot here this year. It's all yours to have a play with - just try not to show me up! 
      It's from the TEC140 Triplet Apo/Mesu 200/Atik 460 mono rig working at about 0.9 arcseconds per pixel, cropped to reduce file sizes and aligned to fit together in Registar. You'll find LRGB and Ha in the link, though the Ha is a bit of a token gesture at 2X40 minutes. However, I found I could use it to give a hint of the star forming regions.  There are no short subs for the central core but I found I could use the RGB layer as a substitute since the core was quite subdued in that set.
      I hope this Dropbox link will work for you.

      Have a great Christmas wherever you are and let's look forward to all those incoming photons in 2019...

      Hi All. Need your help on my first try at M51. After stacking around 1 hour+ of 2 mins exposures this is what I got. I wasn't able to use darks and flats because I had a problem with the darks that I took during that night. I'm getting a slight red tone on the background when I enhance with levels and curves in Photoshop. I took the image in a fairly dark site but I used a UHC filter to see if it has any help on the image. My equipment is a Celestron C6N reflector, Nikon D90, and a Baader UHC filter.
       
      Thanks!

      2hrs with EOS650D at 18Mp shooting visual colour range (240s subs @ ISO800), 1.5hrs with EOS1000D Full-spectrum-modified (no narrowband filters)  at 10Mp (120s subs @ ISO800 as core blows out VERY easily in full spectrum). 5x dark frames and 20x bias frames for the EOS1000D session. No flats. 
      Stacked in DSS 64bit with 2x drizzle, processed in Photoshop CC 2018 (very little needed doing to it to be honest, just pull the saturation up a bit to bring the colour out).
      This is a heavy crop hence the apparent low resolution of the final image.
      This was the last outing for the EOS650D before I killed it, hence no darks / bias applied to the subs from that camera - it died in process of taking it off mount to shoot darks etc whilst I packed everything else away.
