NGC5033 – Spiral Galaxy

with No Comments

NGC5033, at a distance of about 40-60 million light years, is a spiral galaxy with beautifully “flailing” arms, roughly the same size as our Milky Way Galaxy. Imaged March 3 and March 4 2017, with a Celestron 11″ Edge at f/10 and QSI683WSG with Astrodon RGB filters. Roughly 16 exposures of R, G, and B images.       Resolution …….. … Read More

NGC7635 – The Bubble Nebula Wide-field

with No Comments

Revisiting the Bubble Nebula from last year, the area surrounding the Bubble is rich with nebulosity and cluster M52, making it a fine wide-field target.  In this case, I decided to shoot narrowband — typically, narrowband star colors are purple or off-color depending on the palette used, and for this particular image, I decided to mix in natural color RGB … Read More

IC443 – The Jellyfish Nebula

with No Comments

IC443, The Jellyfish Nebula, is a supernova remnant in the constellation Gemini.  At roughly 5,000 light years, the Jellyfish sits near the star Tejat Prior (meaning ‘forward foot’), the left foot of the northern twin.  (Tejat Prior is, itself, a triple star system, at magnitude ~3.2 — so reasonably easy to spot in most skies.) This image consists of 24 … Read More

IC5070 – The Pelican Nebula

with No Comments

The Pelican Nebula is next to the North American nebula (in fact part of it is visible on the left of the image).  This is a narrowband image consisting of 16 Ha 1200s, 12 OIII 1200s, and 12 SII 1200s mapped to RGB in a modified Hubble Palette, taken with a Tak FSQ106 and QSI683 camera. The annotated image shows the … Read More

M74 – Spiral Galaxy

with No Comments

M74 is a beautiful grand-design galaxy in the constellation Pisces, but is also fairly dim and hard to see visually. Captured with QSI683 camera and 11″ Edge SCT at f/10.  LRGB = 32x 10min Lum, with about 16x5min RGB binned 2×2. According to Wikipedia:  Messier 74 (also known as NGC 628) is a face-on spiral galaxy in the constellation Pisces. … Read More

M45 – The Pleiades

with No Comments

M45 – The Pleiades or Seven Sisters is a favorite of mine.  A relatively close star cluster, the dust the cluster is moving through creates a beautiful reflection nebula.   This image was created from 30 600s luminance, 30 300s luminance, 30 60s luminance, and color from 20 each of RGB data binned 2×2 with a QSI683 mono camera and TAK FSQ106 … Read More

NGC1499 – The California Nebula

with No Comments

NGC1499 is a huge nebula resembling the state of California (hence the name).   At roughly 2.5 degrees wide, a full moon could fit about 4 times across in this image — quite large indeed!  In natural light, the nebula is red, but this image is a narrowband 2 frame mosaic (stitched together).  Taken with ta Tak FSQ 106 and QSI683 and … Read More

Sh2-155 – The Cave Nebula

with No Comments

Sh2 – 155, The Cave Nebula, is a wonderful narrowband target as it includes areas of emission and reflection nebulae.  The Ha, OIII, and SII data is mapped to R, G, and B channels to produce the false color image; in natural light, the Cave Nebula would appear red.   Captured with a Tak FSQ106, QSI683 and 3nm Astrodon filters.  40x1200sec … Read More

NGC6888 – The Crescent Nebula

with No Comments

The Crescent Nebula has a number of designations: NGC6888, Caldwell 27, and Sharpless 105.  Captured with a Tak FSQ106 and QSI683 camera, with Astrodon 3nm filters.  21 900sec Ha, 10 900sec OIII, and 19 900sec SII. At the center of the Crescent is Wolf-Rayet star 136.  NASA’s APOD has this fantastic description: What caused the Crescent Nebula? Looking like an … Read More

The Veil Nebula

with No Comments

The Veil Nebula (Narrowband).  The Eastern Veil (top) in its entirety, and about half of the Western Veil on bottom.  Captured with a Tak FSQ 106 and QSI683 with Astrodon 3nm filters.  15x900sec Ha, 15x900sec OIII, 10x900sec SII. HubbleSite.org recently published a fascinating article on the Veil, including some great Hubble Space Telescope (HST) images.  Here’s an excerpt from the … Read More
