Hi All,
I just put up the first draft of last night's imaging effort. I forgot Hubble's variable Nebula was in this field until I saw it on the sub-exposures as I was monitoring the progress. A lot of nice bright and dark nebula as well as several open clusters in this field. https://www.astrobin.com/full/8xu2t2/B/ Details: - Scope -> FSQ-106 at f/3.6 with the 645 reducer - Camera -> ASI2400MC full frame color camera running at gain 158 [unity] at -10C - Mount -> Mach2 running unguided - 108 sec sub exposures. -- Dean Jacobsen Astrobin Image Gallery - https://www.astrobin.com/users/deanjacobsen/ |

I recognize this area - ooks great Dean! I didn't quite appreciate how wide that tak+ reducer ends up. very nice combo On Sat, Jan 21, 2023 at 7:59 PM Dean Jacobsen <deanjacobsen@...> wrote: Hi All, --

Thanks Brian. Yes, the 645 0.72x Reducer QE for the FSQ-106EDX4 is really a nice way to go.

Really nice Dean.
I managed to find a 645 reducer last week, so I’m really looking forward to seeing what I can capture with it, when I get it. It was supposed to arrive yesterday, but didn’t; hopefully early next week. ~Terry |

I might be a while as the weather is supposed to turn really nasty for a long stretch.

Oh my stars that is a wonderful image, Dean. Thanks for sharing. Is it a composite or single frame? John A. Sillasen |

Thanks for taking a look John. The final image is comprised of a stack of 98 x 180 second sub-exposures which are then aligned and stacked by my image processing software (PixInsight). The field is the native field of the scope + reducer + camera combo - about 380 mm focal length - so it is not a mosaic . |

Dean, that is a wonderful shot! Moody kind of vibe. Like it! Stuart Heggie On Sat, 21 Jan 2023 at 22:59, Dean Jacobsen <deanjacobsen@...> wrote: Hi All, |

I've been fiddling around with this one and have posted the final version.
https://www.astrobin.com/8xu2t2/ I can't say that it is "better" than the original... its just different. I did delete the original that I posted and the 6 or 7 subsequent revisions that I have put up on the Astrobin site just to clean things up. -- Dean Jacobsen Astrobin Image Gallery - https://www.astrobin.com/users/deanjacobsen/ |
