IC 447 REFLECTION NEBULA IN MONOCEROS (THE UNICORN)

C 447 is a beautiful complex of reflection and dark nebula two and a half degrees from the well known Cone Nebula. Contrary to the Emission Nebulas, Reflection Nebulas do not emit radiation of its own. The interstellar dust and gas reflects the light energy from a nearby stars or group of stars. In this case IC 447 reflects the light of massive blue stars which are more hotter than our Sun. On the top right corner it can be seen NGC 2245 which reflects the light coming from SAO 95816 shining at magnitude 7,7.

In 1894 American astronomer Edward E Barnard discovered this nebula and informed to Danish astronomer Johan Ludvig Dreyer (the creator of the NGC catalogue and its IC indexes). One year later in 1895 Barnard thought he discovered something different and reported the same object to Dreyer. As a result this object was duplicated in the IC catalogue (IC 447and IC 2169)

NGC 1761; 1763 & 1765 EMISSION NEBULA AND OPEN CLUSTER IN THE LARGE MAGELLANIC CLOUD

The image gathers three interesting deep sky objects not commonly photographed
The open cluster in the centre is NGC 1761 which is embedded with emission nebulas. At the top of the open cluster with 4 to 5 arc minutes we have NGC 1763 (also known as N11 B, LH 10 or ESO 85-EN20). The nebula is very bright and it has an irregular shape. To the right we have NGC 1765 another emission nebula with a smaller apparent diameter.
To the upper left of NGC 1765 we have Globular Cluster NGC 1776 of a bit more than 1 arc minute in diameter.
NGC 1763 and 1765 are part of a large region of stars called LMC-N11 (N11) which was discovered with a 23-cm telescope by Scottish astronomer James Dunlop in 1826 and was also observed by English mathematician John Herschel in 1834.

Lions and Wolf-Rayets and Clusters, oh my!


https://cdn.astrobin.com/thumbs/AEkia8Z ... ouY30K.jpg


The Sh2-132 complex - also known as the Lion Nebula - lies near the border of the Cepheus and Lacerta constellations and contains a veritable zoo of deep sky objects, including two Wolf-Rayet stars, a planetary nebula, at least four open clusters and, of course, the King of this space jungle: the large but faint emission nebula presenting in the shape of a cosmic lion.

I decided to devote substantial time (almost 70 hours) to this target to bring out as much detail as possible in the rich center, as well as the outer nebulosity at the edges of the frame.

The O3 is quite strong and the S2 around the edges of many gas clouds offers nice details, especially near the "back" of the lion's head. With such a zoo of activity in this FOV (including a very dense star field), I tried to bring out a wider range of colors (I think covering the entire visible spectrum) in a way that still looks natural to my eye.

The image comprises 66.5 hours of integration (roughly equal parts of H-alpha, S2, and O3), and was taken from my backyard in Santa Monica, CA under Bortle 7 skies. Processing was done entirely in PixInsight, and the gear used was as follows:

Camera: ZWO ASI6200MM-pro
Scope: William Optics Fluorostar 132mm Refractor
Mount: Astro-Physics Mach2GTO
Filters: Chroma 3nm Ha/S2/O3 50mm
Guide Camera: ZWO ASI174MM-mini
Accessories: ZWO OAG-L, Pegasus Powerbox Advance

Additional detail is available at the image link referenced above.

Respectfully submitted,
Aaron Wilhelm

20230101 Visible vs Thermal Moon
There are 2 interesting facts from the images:
1. The lunar maria in optical light are darker areas, however, they absorb more visible light, so they get warmer and emit more LWIR light in the thermal image which looks brighter.
2. At the terminator line, both visible light and LWIR light are similar because being lit or not dominates both the reflection and the temperature of the surface.

NGC 2506 IN MONOCEROS (THE UNICORN)

NGC 2506 (aka Melotte 80, Collinder 170 or Caldwell 54) is a quite populated and concentrated open cluster in Monoceros. 94 probable members have been identified within the field of NGC 2506 based upon their radial velocities. Compared to the Sun, the cluster is moderately metal-poor. This is an old star cluster with a calculated age of more than 2 billion years old. It has a number of red stars and Red Giant Branch (RGB) stars, but it also has a number of member stars that appear to be younger spectral types despite its estimated age.

R LEPORIS (aka HIND'S CRIMSON STAR)

R Leporis (R-Lep) is a carbon star which are typically an asymptotic giant branch star, a luminous red giant, whose atmosphere holds more carbon than oxygen. R Leporis is too far from earth for its parallax to be measured effectively. It was estimated a distance of 1,350 light-years, shining with a luminosity of approximately 6,689 times our Sun and has a surface temperature of 2,980 K
R Leporis has often been reported as an intense smoky red color, although this is not pronounced when the star is near its maximum brightness. It is reddest when it is dimmest, which occurs every 14.5 months. During these periods it is a candidate for the most-visible reddest star, but this claim is questionable.
By comparing with the other stars in the image, I presume that R-Leporis is transiting (December 2022) its low brightness stage showing probably a magnitude between 8 or 9 (v)
It was named after famous British astronomer John Russell Hind, who observed it in 1845.The star's discoverer reported that it appeared "like a drop of blood on a black field."

As a friend of open star clusters, you have to capture NGC 457 in the constellation Cassiopeia.
It is the brightest open star cluster in Cassiopeia and one of the most beautiful objects of its kind in the northern sky. With a brightness of +6.4, it is barely visible to the naked eye, but easy to see with binoculars and a beautiful sight with a telescope.

I captured another set of thermal images the next day and the stitching result seems even better. I hope you like them.

The Running Man Nebula - 5h RGB Dreyer's Nebula - 7h RGB
Full sizes available from: https://www.flickr.com/photos/190058450@N06/

Both of these images were taken out at Alamo Lake State Park, AZ, which is a nice Bortle 2 site located in the Arizona desert. I shot the pictures over the course of 12/23/2022 to 12/27/2022 (including Christmas night!), using a 12in Newtonian paired with a QHY268M and Antlia RGB filters. A CEM70N Mount was used to support the telescope along with a Berlebach Planet tripod. Both images were processed with PixInsight. I'm quite happy with how both of these images turned out - these are the first broadband images I've been able to take with my new large Newtonian, and I'm very excited to share them with you all.
