Observing report, TV76, 2/4/05
Date: Friday evening, 4-Feb-2005
Location: Backyard, Palm Springs, California Equipment: Tele Vue 76 (3" f/6.3) refractor Revisited a few of the objects from a couple nights ago again with the TV76 plus some new ones. Tried to spot some nebulosity in NGC 2264, the "Christmas Tree" cluster, but could not. However i could see NGC 2261, "Hubble's Variable Nebula", as a very small patch through the 9mm Nagler. Oddly when i tried with the UHC filter i could not see the nebula at all. The Rosette nebula was interesting. With UHC on the 9mm Nagler i could see a sort of grayish mottling around the central cluster. Mostly noticeable to the north. It's hard to describe what it looked like. There was "something" there but it didn't really look like a nebula at all. Just a strange presence that didn't look like empty space. Revisited open cluster NGC 2301. I really like this little cascade of a cluster. Open cluster NGC 2232 contains the star 10 Monoceros. Pretty field with tendrils of stars dangling southward from the bright star and an arc of stars just NW. Nice binocular field as well. Open clusters NGC 2335 and 2343 are both rather small and faint. Can only resolve a few stars in 2335 whereas 2343 is sort of boxy in shape. Both fit in the same 53x field. NGC 2353 contains one bright star that seems to overpower the rest of the cluster. Last couple of objects are just over the border into Puppis... M47 is beautiful! Bright, large, very nice through the TV76. Interesting patterns of stars with a nice double near center at the southern tip of a little "kite" of stars. M46 is also large but very different from M47. Fainter stars but lots more of them. Jerry Lodriguss' image of the clusters compares them well... http://www.astropix.com/HTML/B_WINTER/M46_M47.HTM And for a special treat when i put the UHC on the 9mm Nagler planetary NGC 2438 popped into view! Note the red planetary is visible in the image as well. -Florian Stargazing.com |

small patch through the 9mm Nagler. Oddly when i tried with the UHC filter i could not see the nebula at all. I also find that UHC kills that nebula with my 80mm. It's a reflection nebula after all. Without a filter it looked like a small version of the Christmas tree cluster - same proportions and orientation. Dmitri |

That is not surprising, since the nebula is more of a reflection nebula than an emission type. I find that the broadband Lumicon Deep-Sky filter works better on this object than the UHC, although with a large aperture, the UHC will work a bit on it as well. Clear skies to you. -- David W.

than an emission type. Hi David, You are correct of course. I was somehow thinking it was an emission = neb. -Florian |
