  1. Difficult to observe with an optical telescope, Barnard 33 - better known as The Horsehead Nebula - is a dark dust cloud overlaying the HII bright nebula IC434. To view it directly normally requires very dark skies, clear air, a large (14" or larger) telescope, and an Hb or Ha filter, making it one of the more challenging objects to observe.

    For the Traveller fans, it is 422 parsecs away - or about 70 weeks if you could take a direct Jump 6 path to it. It is also just under 1 parsec across - that's a 1 hex object. IC434 is less than a parsec behind it, and is over 4 parsecs across, making it a 4 hex object. Nebulae are one thing (of many) that Traveller tends to gloss over, simply because they are so huge! There is also the matter of such regions being star nurseries, typically with ten or more stars within a single hex. These will all be too young to have any planets, let alone habitable ones!

    Back to the real world, though.

    With Electronically Assisted Astronomy - in this case provided by a Dwarf3 smart telescope - it becomes an easy object to capture. A mere 37mm lens and a built-in Ha/OIII filter gave a visible image within a few minutes, and an hour of stacked images provided this view.

  8. Only 1 hr on the Horsehead and Flame Nebula with H-alpha filter. This is going to be good. It needs about 10 more hours and some RGB stars.

  9. Barnard 33 Horsehead Nebula

    Magnitude 6.8 dark nebula located 1,375 light-years away in the constellation Orion. The nebula was first recorded in 1888 by Scottish astronomer Williamina Fleming on a photographic plate taken at the Harvard College Observatory.
