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.

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 1

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.

The Lagoon and more...

Finally a clear night. We don't get many here in southern Connecticut. The following images were taken on Thursday 7/16/15 from my favorite location very close to my house. Also this was a beta test for the my autoguider setup. It is basically the Orion Awesome AutoGuider Refractor Telescope Package only the Orion StarShootAutoguider Camera is replaced with the Orion StarShoot G3 Deep Sky Imaging Camera. I purchased the G3 camera at the start of this hobby but switched to a DSLR as they are easier to manage and more versatile. So the G3 finally has an important job.

Longer Exposure, Better Image

The following images are of the Ring Nebula.  The first is from 6-22-15 and the other two are from 6-19-15.  I wanted to see how increasing the exposure time affected the images.   They had a profound affect, at least to me.  The one problem is there is an increase in the noise.  Perhaps even more stacked images would fix that problem. That will be another night...

A Good Night Part Two

For the end of the observing session (Part Two) with Boothe Memorial Astronomy Society on Friday (6/19/15) evening we observed the Ring Nebula (M57 or NGC 6720) in the constellation of Lyra and the Great Cluster in Hercules (M13 or NGC 6205) in the constellation of Hercules. Special thanks to Elliott Severn for pointing these objects out.

The Ring Nebula is a very small object which makes it hard to image. A higher resolution camera, a larger aperture telescope, or longer exposure image would improve the image quality. For these images I used an 80mm Orion ED80 refractor, a Canon Rebel T3i, and the total exposure was less than a minute. In the future I will try this again with a longer exposure. If that doesn't work I will try with my 8 inch Orion SkyView Pro reflector, although it is not as easy to set up as the ED80.
