Clouds of the Milky Way
Now that summer has ended, the summer Milky Way is headed west and will soon be replaced by that part of the sky dominated by galaxies. Here is a last look at part of the Milky Way laced with clouds of hydrogen.

This past weekend I cruised all around this area with my 25"dob... but it sure didn't look like that! \Paul A |

Best you can do is with an H-beta filter, or a narrowband nebula filter. Still, these are faint clouds that are recorded easily with a fast optical system. At 12" aperture and F3.8 this is achieved in very short exposures of 300 seconds or so. UncaNebula |

It is a little wider than an OIII and a little narrower than a UHC, but it works well on many objects, including faint nebulosity, it boosts the contrast nicely. |

At 12" aperture and F3.8 this is achieved in very short exposures of 300 seconds or so. Or with slightly longer exposures with a 4" or 6" aperture, as seen at http://www.primordial-light.com/deepsky8.html! -- I agree with almost everything that you have said and almost everything that you will say in your entire life. usenet *at* davidillig dawt cawm |

Yes, you don't need a 12" aperture to capture clouds of the Milky Way. You can do it with a 50mm lens if need be. But if you have the aperture, why not ;^)) UncaNebula |

Unfortunately, various factors-- mainly Mid-Atlantic weather, but others, as well--have kept me out of the observatory of late. When I do manage to get a half-decent photo I credit my A-P 1200. Telescopes, cameras, guiders, none of the rest of it is worth anything without a quality mount. Yes, you don't need a 12" aperture to capture clouds of the Milky Way.

The "why" I don't have 12" of aperture is tied to a) the size of my tiny 2-meter dome b) the quality of the skies in the Mid-Atlantic c) my limited skills. No sense giving a Stradivarius to an earthworm. -- I agree with almost everything that you have said and almost everything that you will say in your entire life. usenet *at* davidillig dawt cawm |

Size does not matter, just persistence. UncaImager |
