This is a beautiful example of galactic dark nebulae at high latitudes that become visible through illumination by the interstellar radiation field, known as Extended Red Emission (ERE). ERE is a dust-luminescence process, which appears in a broad band extending in wavelength across the R-band. ERE also often appears in narrow filaments on the edges of clouds and may therefore be mistaken for H-alpha emission. This nebula emits no significant H-alpha signal. It's shape reminds of a cometary globule in its very last phase before being dispersed. [Source: Panther-Observatory.com].

LBN 438 is a dusty nebula within our galaxy. Despite being part of the Lynds Bright Nebula catalog it is very faint. This is the largest fragment of the nebula. There are many smaller fragments outside the field of view. [Source National Optical Astronomy Observatory: T.A. Rector (University of Alaska Anchorage) and H. Schweiker (WIYN and NOAO/AURA/NSF) ].

The image was captured with the Meade 12"LX200, using the Atik 383L+ mono at F7.16. Astronomik's LRGB filters were used. All subs were taken at 1x1 bin, -10C, and 10 minutes each.

First Image:

Lum : 40 subs (6.66 hr) on Sep 27th, 28th and 29th.

Red : 11 subs (1.83 hr) on Sep 27th and 28th.

Green : 11 subs (1.83 hr) on Sep 28th and 29th.

Blue : 10 subs (1.66 hr) on Sep 29th.

Second Image:

Lum : 68 subs (11.33 hr) on Sep 27th, 28th, 29th and 30th.

Red, Green and Blue: Same as Above.

Third Image:

Lum : 100 subs (16.67 hr) on Sep 27th, 28th, 29th, 30th and Oct 01.

Red, Green and Blue: Same as Above.

Processing was done with PixInsight, following (for the most part) kayronjm's tutorial of Feb. 24th. Only L was used to develop the Luminance image. R, G and B were collected for the color mix.

The large dim nebula (towards the left) is the main target for this image. But notice also the small face-on and edge-on spiral galaxies located just about center of the image.

North is up, and this is a very slight crop. This is my first full use of the Plate Solve capability within Sequence Generator Pro (using Astrometry), and I am very pleased with it.

I have seen that by adding more subs to the Luminance, the image takes on more detail. So I intend to try to double the number of subs at present (currently 40), and hope this is noticeable.

UPDATE:

The second and third (last?) images includes an additional 28 and 60 LUM subs. While subtle, they are a bit more detailed and less noisy.
