Enwrought with golden and silver light,
The blue and the dim and the dark cloths
Of night and light and the half light,”

  • NGC1333 9 hours of exposure , taken by Lynn Hilborn, Grafton,Ontario with NP101is@f4.3 and ML8300 camera...October 10 and 12, 2010.<br /> Photo published in SkyNews magazine Jan/Feb 2011<br /> Distance: 720 Light Years<br /> <br /> Right Ascension: 03 : 29.3 (hours : minutes)<br /> Declination: +31 : 25 (degrees : minutes)<br /> <br /> <br /> <br /> Text copyright Robert Gendler<br /> <br /> NGC 1333 is catalogued as a reflection nebula but is actually a diverse region and part of the Perseus OB2 molecular cloud complex. It is one of the nearest star forming regions and particularly rich in young stellar objects (YSOs). Stellar clusters are born embedded within molecular clouds and during their early evolution as YSOs are often only visible at infrared wavelengths, being heavily obscured by dust. Four classes of young stellar objects have been described. Class I though III objects progress through an evolutionary sequence of being less dust enshrouded, as they develop towards the zero-age main sequence. The earliest and most imbedded stage of star formation is the class 0 YSOs. These earliest protostars are difficult to detect due to their heavily imbedded nature. Less than 50 Class 0 objects are known however 4 of these low mass protostars exist in NGC 1333. Also 36 Herbig-Haro obejects have been identified in NGC 1333 confirming its status as a young active region of star formation. Herbig-Haro objects are collisionally excited nebulae produced by outflows ejected by YSOs. They are produced mainly during the first few hundred thousand years of life of a YSO and are usually highly obscured by the cloud core environment from which they formed.<br /> <br /> The gaseous structure of NGC 1333 has been mapped at radio wavelengths and appears to support the large scale star formation observed. Lumpy and filamentary cloud structure exists in NGC 1333 indicative of recent collapse and fragmentation of the parent molecular cloud leading to the clustered mode of star formation observed in the nebula. In addition a series of cavities and shells exist presumably blown out by the outflows of infant protostars. Infrared surveys reveal the presence of YSOs at the edge of these cavities indicating that sequential star formation has occurred there and has been triggered by the effects of the powerful outflows from the first generation of stars. The entire process is extremely recent as the cloud hosting NGC 1333 is less than a million years old.'
  • Bubble nebula (reprocessed in Images Plus)....2 hours Ha (8x15m subs), 1 hour RGB (10mx2 each RGB). Just collimated my C9.25 and added a f6.3 reducer and crossed my fingers. Camera is a FLI ML8300 at -35C. Taken by Lynn Hilborn at WhistleStop Obs, Grafton, On...October 2009

  • Crescent Nebula NGC6888...3.5 hours of Ha 7nm with ML8300 @-30, NP101is.<br /> Sept 15, 2009 by Lynn Hilborn, WhistleStop Obs 44N78W
  • The cover story of the July edition of Sky and Telescope is about the finding of the Soap Bubble nebula by an amateur astronomer. Page 34 of the magazine had a picture which was almost the same field of view to one I took last September. Above is my September shot and buried in the bottom left quadrant is this elusive object...boy is it faint. NP101is telescope and ML8300 camera. Exposure 14x15m in Ha.
