Catching the Dumbbell Nebula during the Meteor Shower

While watching the Persiad Meteor Shower Wednesday night/Thursday morning (and trying get photo with my old camera) I had another go at it with my autoguider setup (see autoguider post) imaging the the Dumbbell Nebula (M27).  The Dumbbell Nebula is a planetary nebula, formed from an exploding star 9800 years ago (estimated).  It located in the constellation Vulpecula (halfway between the bright stars,  Deneb and Altair of the Summer Triangle) at a distance of about 1360 light years from Earth.

The image was made by stacking nine exposures each 90 seconds for a total time of 14.5 minutes. The autoguider worked perfectly as the stars show no trailing.

I did manage to get a shot of a meteor during my viewing session and some shoot of the faint Milky Way from my light polluted front yard in southern Connecticut.

Working with deep sky stacker

Reprocessed an image of the Hercules Globular Cluster I took a few weeks ago in Deep Sky Stacker (DSS) with much better results. Image 1 is from TIFF files converted directly from the RAW data and Image 2 was stacked using JPEG format. I had trouble stacking on the RAW files using DSS directly which is why I converted them to TIFF files.

Using an Orion StarShoot G3 as an autoguider

Finally getting my autoguider setup to work.  I use PHD2 Guiding by Stark Labs to run the autoguider and mount.  I am assuming you already know how to use PHD2 Guiding,  I if not, I recommend Astrophotography P3: Guiding Your Telescope by Forest Tanaka.

My hardware consists of an Orion StarShoot G3 Deep Space Color Imaging camera connected to an Orion ShortTube 80mm telescope as my autoguider.  Other incidentals, I use an Orion ED80 refactor telescope, a Canon Rebel T3i (600D) camera, an Orion Sirius EQ-G mount, and Backyard EOS for camera control.  The G3 is not inherently designed for use as an autoguider and took some research, a few calls to Orion tech support, and lots of trials in order to get it work.

A few things to be aware of: 

1) The G3 requires a guide scope with a larger aperture than the 50 mm standard guidescope size on the StarShoot Autoguider (you also need to order a RJ12 cable to connect the G3 to the mount).  

2) The G3 Firmware driver has to be up to date, if not, contact Orion and they can help with that.  

3) When using PHD2 Guiding, the G3 is not a selection on the Camera icon, you must select ASCOM (Late) Camera and then the G3 appears as a selection. 

4) But wait, there’s more, you also must select On-camera under the Mount tab at the top of the page. The rest of the set up should be how you would normally set up PHD2 Guiding. If not, call Orion. 

Also, I am new to using most of the software.  With this in mind my original stacking, Image 3, was done off of jpeg files as DSS was not stacking the raw files correctly.  Later I discovered I had to convert the raw images using Digital Photo Professional (Canon software) to TIFF files and then stack them.  The images below are of M31 - Andromeda Galaxy (M32 and M110, satellite galaxies of Andromeda are also visible).

Results:

I pride myself on good polar alignment and tracking and Image 1 is a 100s exposure of Andromeda where I thought it was tracking well but obviously not as well as I thought.

Image 2 is a 100s exposure of Andromeda after the autoguider tracking was synchronized using PHD2 Guiding.  This took approximately five minutes.

Image 3 consists of six 100s exposures of Andromeda stacked using Deep Sky Stacker (DSS).

Image 4 and Image 5 are after processing Image 3 using Photoshop.

Image 6 is after processing the six original raw images in DSS.  Prior to using DSS I had to convert the Canon specific raw images into TIFF format.  Apparently DSS has trouble converting certain Canon raw images.  Notice the galaxy is flipped when the raw images were stacked.  Final processing was done in Photoshop.
