Its been a really long time I did some imaging and I have to say it wasn't that easy to start again. 

Also been updating Ascom and APT software and used phd2 for first time. So this was more of a training run..

I took a reasonable easy target NGC6888 (or Crescent Nebula.) I ended up with 21 lights x 240 sec iso 800.

Processing was like doing it for the first time to again (lol) and I will try doing it bit better later but ill post my first result now to.

Software: CDC 4.0, PHD2, APT 3.3 , EQASCOM v29a

Hardware: Skywatcher 150 pds, QHY5, Canon EOS 1100D, HEQ5 Mount


Clear Skies,

Nice effort, it's a difficult target with a DSLR, i've tried it myself in the past, i think it just needs many, many hours of data.

      There's a lot wrong with this image! Egg shaped stars because I didn't have the spacing right etc. 
      But great fun to be imaging again for the first time since March - more notes in table below re processing etc.
      Object name
      Crescent Nebula
      Object ID
      NGC 6888
      5 Aug 17
      Altair 115mm
      19x5 min
      Total time
      1.5 hours
      PixInsight / Bias, Flats, no darks / Levels / Curves / ATWT
      With a full Moon low in the South I couldn’t image this object in colour, but with narrow band filters I was able to get a good set of h-alpha sub frames to process.
      As this was the first imaging session of the year it was inevitable that things were not going to go perfectly.
      Thankfully the guiding with PhD 2 worked perfectly and I was quickly capturing subs. However, I didn’t have the spacing right between the camera and the field flattener and this resulted in egg shaped stars at the four corners of the image. I figured out that I had included a 50mm nose piece adapter where I should’ve just screwed the filter wheel directly to the flattener. A large note has been made :-)
      Amazing that I’m able to image in the light of a full Moon and get some results to practice with.

      The Crescent Nebula NGC 6888
      The Crescent Nebula rides on the Swan’s neck in Cygnus in a dense swathe of Milky Way stars - an ideal target for my first bi-colour image with my new Astrodon 3nm Ha and OIII filters and Esprit 150 telescope.
      The nebula was discovered by William Herschel on 15th September, 1792 and he described it as ‘A double star of the 8th magnitude with a faint south preceding milky ray joining to it.8’ long by 1.5’ broad’. This double star is not the prominent star with an apparent companion close to the heart of the nebula, rather, it is ADS13515 at the 2 o’clock position on the nebula’s bright periphery. The bright star off-centre of the nebula is particularly significant as this is the star that is powering the emissions from the surrounding gas cloud. This magnitude +7.5 star, HD192163, is of the Wolf-Rayet type and is also designated WR-136.
      Charles Wolf and Georges Rayet first described wolf-Rayet stars in 1867 following detection of their broad emission lines. The Wolf-Rayet stage applies to stars with an original mass in excess of 30 times our own Sun’s mass. This stage comes late in the star's evolution when a rapidly expanding shell of hot gas is powered outwards by the stellar wind only to collide with the much slower-moving gas clouds that were ejected thousands of years previously when the star entered its Red Giant phase. These forceful collisions produce a shock wave that generates an enormous amount of energy including wavelengths within the light spectrum, allowing us to observe them. This complex process displays as an arc of bright nebulosity that we identify as the Crescent Nebula. Long exposure images fill in this arc producing a crab-shell shaped nebulous region rich in Hydrogen Alpha and doubly ionised Oxygen emissions. WR-136 is fated to go supernova at some time in the future – watch this space!

      The Crescent Nebula – NGC 6888

      Comparison of Ha and OIII data
      We imagers (well me anyway!) tend to think that Ha is the all-powerful emission line in nebulous objects but it is interesting to compare the Ha and OIII data for this structure as there is an enormous amount of OIII emission present in The Crescent Nebula.

      Typically, my first light image with my new 3nm Astrodon Ha filter took place under almost full Moon conditions but in some ways, this was quite a useful test in its own right as clear skies and full Moons seem to attract one another!  There isn't much in the way of available nebulae around this time of the year so an early riser like the Crescent Nebula seemed as good a choice as any but I had to wait until 00:20 before I could get started. Nice to see the Soap Bubble Nebula in there as well.

      I think I'm going to like this filter .....

      This is my RBG data from rural Sweden with a Canon 60Da and a 5" ES apo refractor (22 x 480") and Ole Alexander Ødegård´s Ha data from rural Norway with his mono modded Canon 6D and a 12" TS imaging Newton, so almost 5 hours total. I could probably have been a bit softer in the processing but it is also nice with a bit of drama in the picture. I have been starring on it enough now and would like to hear what you think, so any comments are welcome!

      I have done some nebula hopping (Western Veil, Cave, Flying Horse / Wizard and Crescent) during the recent clear nights 3 - 5 October. Now clouds are back and I post what I have got. All with the ES 127 ED apo and Canon 60Da on the EQ8 mount. About 3 - 4 hours of data except for the Cave that only got an hour. Should collect some Ha for them.
