DG 41 and surrounding area in Taurus

I was going through my computer today and stumbled upon a data set that I had processed in January of this year (two weeks shy of being a year ago) and had completely forgotten about some how.

The data in question is of DG 41, a reflection nebula that is in a cloud of dust. The data was collected in November and December of 2015 and consists of 7.5 hours of Luminance, 8 hours 10 minutes each of Red and Blue, and 7 hours 10 minutes Green data.

Here it is:

DG 41, also named GN 04.32.08, Magakian 77, or Bernes 83.

That's about it, don't know how I forgot it but I'm glad I found it.

Thanks for looking.

Veil Complex in a funky HST

Here is the finished Veil complex image from the data collected this summer. This includes 6 hours and 20 minutes of HA and 6 hoursand 30 minutes of OIII and SII data. It's processed in an adaptation of Bob Franke's color manipulation of the HST palette. The purists probably won't like this much but I think it came out pretty cool.

Here it is:

Veil Complex in narrowband

The Veil complex consists of NGC 6960, NGC 6992, NGC 6995, NGC6975, NGC 6979, and Pickering's Triangle. It is a large but faint supernova remnant.

Thanks for looking.

NGC 6951 or NGC 6952 and a whole lot of dust

Here is the next image I've processed from the data coming out of the observatory. It is of NGC 6951 or NGC 6952 depending on which catalog you look in and the surrounding Integrated Flux Nebula.

This spiral galaxy is 75 million light years away and is classified as a Seyfert Type II galaxy that we view face-on. Even though it appears tiny in the picture below it is a galaxy containing billions of stars.

NGC 6951 and a lot of dust in Cepheus

This image is comprised of over 20 hours of data. We captured almost 24 hours in total but only kept the best data which came out to 300 minutes of blue and green, 330 of luminance, and 270 minutes of red in ten minute sub exposures.

Thanks for looking.

Quick process of the Veil Complex in HA

With the moon up we've switched to narrowband imaging and began capturing data on the Veil complex. It is also referred to as the Cygnus loop and is a large supernova remnant.

So far we've gathered a couple of hours of Hydrogen Alpha (HA) consisting of ten minute exposures. Because our scope doesn't have a rotator the field of view is a little different than how you would usually see the Veil presented but I was happy that even at this odd position angle I was able to fit the entire complex in the frame.

Here's what we've got so far:

The Veil Complex in HA

As time and weather allows we will be adding Sulfur II (SII) and Oxygen III (OIII) data to complete a color image.

Thanks for looking.

IC 1318 - Sadr Region or The Gamma Cygni Nebula

This is a pretty part of the sky Jim suggested we image.

This data was collected over the course of three nights and consists of three hours per color channel (Red, Green, Blue, and Luminance) for a total of 12 hours of data. Needless to say it was pretty easy to process with all that signal. :-)

IC 1318 - Sadr Region/The Gamma Cygni Nebula

Despite the heat in Texas making the camera's cooler work overtime the observatory continues to purr along gathering good data so as long as there are clear nights we'll keep sending it plans.

Thanks for looking, clear skies everyone.
