Sketches

The Shark Nebula LDN1235 two panel mosaic

Recommended Posts

After a very busy Spring and early summer with work, much poor weather in Spain, I am able to return to some imaging and get a better work-hobby balance!

Steve and I are busily hoovering photons on various projects with one just completed - a two panel mosaic of the Shark Nebula in Cepheus.  APOD describes it thus: "There is no sea on Earth large enough to contain the Shark nebula. This predator apparition poses us no danger, though, as it is composed only of interstellar gas and dust. Dark dust like that featured here is somewhat like cigarette smoke and created in the cool atmospheres of giant stars. After being expelled with gas and gravitationally recondensing, massive stars may carve intricate structures into their birth cloud using their high energy light and fast stellar winds as sculpting tools. The heat they generate evaporates the murky molecular cloud as well as causing ambient hydrogen gas to disperse and glow red. During disintegration, we humans can enjoy imagining these great clouds as common icons, like we do for water clouds on Earth. Including smaller dust nebulae such as Lynds Dark Nebula 1235 and Van den Bergh 149 & 150, the Shark nebula spans about 15 light years and lies about 650 light years away toward the constellation of the King of Aethiopia (Cepheus)."

I captured part of the Shark a couple of years ago when imaging its smaller fishy cousin LDN1250 (here) and am pleased to have captured the whole predator!

Details:

  • Tak FSQ106 at F5
  • QSI683wsg-8 with Astrodon filters
  • 10 Micron GM1000HPS
  • Each panel has Lum 36 x 600s; 16 x 600s RGB each; total integration 28hrs
  • Captured with SGP, processed with PI
  • Captured by Barry Wilson & Steve Milne; processed by Barry Wilson
  • Our remote observatory at E-Eye, Spain

Thanks for looking & CS!

Another cracker Barry, well done both, hopefully the weather will improve from hereon.

Good news, just received a replacement controller from 10Micron this week so may actually be able to get on with some imaging, they did send one with old firmware so had to update it before use for the MGBox.

Lovely work Barry (notice use of the word ‘work’, for when considering the work-hobby balance!!). Stunning big fish and beautiful star colour. Isn’t it great knowing that we are now gently slipping back towards astronomical darkness!

I saw steve's version on astrobin and again very little between them given the very different tools used. Beautiful work.

Thanks very much Richard - with such a beautiful target it is relatively simple to achieve a satisfactory result.

Thanks Gav.  Yes, looking forward to some real darkness in the UK.  I've just received a 'new-to-me' Atik One 9.0 so will be experimenting with 0.82"/px scale with my WO 132FLT at F7 . . . ?.
