Deep Sky Astrophotography by Barry Wilson

Current Projects: (1) Rosette Nebula core NGC 2244 and its Carnival of Animals

(1) Rosette nebula core

This image comprises recent Ha data from e-Eye from the TEC140/QSI690 Steve and I operate and SII, Ha and OIII data from my home observatory in Totnes acquired in 2018 using my WO 132FLT/QSI683 at 1.47"/px, here. Steve and I have been imaging the Rosette core at 0.75"/px early evening as the moon has been rising before switching to other targets mid-evening. We will not be able to collect the SII and OIII this season so I processed the 28 x 1200s of Ha and re-aligned my older image to provide the 'colour' for the higher resolution Ha data: it is effectively like imaging bin 1 for the Ha and bin 2 for the SII and OIII. After a crop to take care of the mis-aligmnent and some additional NR due to the resampling, a few enhancements, et voila! The 'Carnival of Animals' reference is of course the resemblance of the dark dust to a troop of fantastical animals and Saint-Saens humorous musical suite. . . which animals, well your guess is as good as mine.

ABOUT ME

I have been fascinated with astronomy since childhood ever since I read Patrick Moore's "The Observer's Book of Astronomy" and became a devotee of BBC's "The Sky at Night". This website aims to display what can be achieved by an amateur astrophotographer in their backgarden - Totnes, Devon, UK, in my case - equiped with dedication, patience and perseverance, especially from my family!  I also share a remote observatory in Spain with Steve Milne, equiped with our own equipment, setup by ourselves and jointly operated and controlled.

Clear Skies!

Nebulae images

IC 2177 The Seagull Nebula

IC 2177 The Seagull Nebula

This is a 'work in progress' image as we gather the data for a HOORGB image which will take a couple of seasons to gather the necessary data. The four panels have the minimum data really to produce this test image and we do in fact have two further panels for a row across the bottom of the image but as yet no data! This target is low even at e-Eye's latitude and so imaging in the turbulent lower atmosphere we are relieved to see little distortion and refraction effects on the RGB channels for the stars.

I have wanted to image this very pretty target for some time and am delighted we have persevered sufficiently for an HaRGB image. So I am pleased to add my version to the many fine Seagull (or Parrot) Nebula images posted recently.

From Wikipedia: "C 2177 is a region of nebulosity that lies along the border between the constellations Monoceros and Canis Major. It is a roughly circular H II region centered on the Be star HD 53367. This nebula was discovered by Welsh amateur astronomer Isaac Roberts and was described by him as "pretty bright, extremely large, irregularly round, very diffuse." The name Seagull Nebula is sometimes applied by amateur astronomers to this emission region, although it more properly includes the neighboring regions of star clusters, dust clouds and reflection nebulae. This latter region includes the open clusters NGC 2335 and NGC 23."
