NGC 7331 and the Deerlick Group

The NGC 7331  galaxy group, better known as the Deerlick group, consists of NGC 7331 (10.2),the main galaxy at 40 million light years distant, and NGC 7335 (14.5), 7336 (15.6), 7337 (14.5)  and NGC 7340 (15.4). These smaller galaxies are known as the fleas and  are more than 300 million light years away.  There are many fainter galaxies in the field.  Some of them aren’t shown on the chart (below).  The group was imaged at Transit Dreams Observatory on October 20, 2017.  Capture data is below.

Comet C/2017 O1 (ASASSN1)- motion video

 

Here is a video created with the (40) 90 second images stacked into the image shown in the previous post.  The comet was moving at 2.8 arc sec/min as it passes its closest point to Earth.

C/2017 O1 (ASASSN1)

Comet C/2017 O1 (ASASSN1)  reached perihelion on October 14th, and be closest to Earth on October 18th (today), at a distance of about 75 million miles.  The image above was captured and measured on October 17th, and consists of (40) 90 second exposures stacked on the comet in Astrometrica.  The details are below.

NGC 7635 (Bubble Nebula)

 

The Bubble Nebula (NGC 7635) is an emission nebula in Cassiopeia. It is about 10 light years across and lie about 8000 light years distant. It was formed from a Wolf-Rayet star who’s stellar wind created the bubble shape.

 

The image above was captured using a 7nm Hydrogen-Alpha filter. The red is false color created from Carboni’s tools in Photoshop. The image details are below.

LDN 1369

I haven’t had much time for pretty pictures, with the inhospitable summer weather, and my focus on the asteroids. I wanted to share something I started working on at the beginning of this year, but haven’t had the time to collect more data.

This is one of Lynd’s Dark Nebula from his catalog. I was scanning my SkyX software looking for appropriate targets for my setup when I came across this beauty. Later on I discovered it’s actually the central core of the Heart Nebula in Cepheus (IC1805).

This is a very noisy image because I’ve only collected about 1 hours data on it, but I don’t know when/if I’ll have the opportunity to collect any more, and I wanted to share it with you. It was captured using my ccd camera on the 127mm refractor, using a 7nm Ha filter from Orion. The red colorization was added in the post processing using Photoshop.

I hope to one day add more Ha data, and add some RGB to bring out the star colors. I hope you enjoy it.
