PK164+31.1 Planetary Nebula


©2006 Richard Murray

Techno Stuff: 4/10/07 ATK-16hr, Megrez 80mm APO at F/6 mounted on LX90 8" SCT, Ha Filter 6nm, 45 mins total exposure with 1x10mins, 1x15mins, 1x20mins, Binning 2x2, manually guided from LX90 with ATK-2HS, no darks, Photoshop CS2, Image Analyzer, Silkypix

Notes:Also known as the Headphones Nebula, this is a very faint, 14.0 mag, planetary nebula located in the Lynx constellation. The image was taken at a low altitude with low level fog and in the direction of the most heavy light pollution at my site. The Astronomik 6nm Ha filters ability to cut through these obstructions is the only reason this faint object registered on the CCD at all! :>))

NGC3628 and the Trio in Leo


©2006 Richard Murray
Full Size Image

Techno Stuff: 3/20/07 ATK-16hr, Megrez 80mm APO at F/6 mounted on LX90 8" SCT, Red filter and IR filter, 6x600secs, manually guided from LX90, no darks, Binning 2x2, Photoshop CS2, PixInsight, Neat Image

Notes:This is the often imaged 'Trio in Leo' of three Galaxies located in the Leo Constellation. The framing isn't the best but it was a balance of trying to remain in as close as possible and finding a suitable guide star. The brightest galaxy, NGC3628 ((mag 9.5) is at bottom.

IC443 Jellyfish Nebula




©2006 Richard Murray

Techno Stuff: 3/17/07 ATK-16hr, Megrez 80mm APO at F/6 mounted on LX90 8" SCT, Astronomik Ha 6nm filter, 8x600secs, autoguided with LX90, darks applied, Binning 2x2, Processed in Registax3, Photoshop CS2, PixInsight

Notes:This is the second image taken with my new Megrez 80mm APO which is piggybacked on my LX90. I used an Astronomik 6nm Ha filter which does an excellent job of filtering out light pollution even at very low altitudes.

This image is my first tenative step towards learning nondistructive image processing through the use of adjustment layers where no permanent changes are made to the image except at the last stage of processing. I'm using R. Scott Ireland's excellent book, Photoshop Astronomy, to learn this technique.

The top image was stacked in Registax3 and the middle image was stacked in Photoshop CS2.

The bottom image is the result of applying a technique in Photoshop CS2 to the middle image which was learned in the Astro-Narrowband Yahoo Group as follows:

Create a duplicate layer
Apply a minimum filter with 1 pixel
Apply a high pass filter with 3 pixels
Set blending mode to Overlay
Set Opacity to taste (I used 80%)
Flatten image.

M51 Whirlpool Galaxy - First Light With Megrez 80mm APO


Full Size Image

©2006 Richard Murray

Techno Stuff: 2/23/07 ATK-16hr, Megrez 80mm APO at F/6 mounted on LX90 8" SCT, Red and IR filter, 2 x 480 secs, autoguided with LX90, no darks, Binning 1x1, Processed in Photoshop CS2, PixInsight

Notes:This is the first image taken with my new Megrez 80mm APO. After aligning the scope on top of the LX90 and a few mishaps, adjustments, balancing etc., etc.. I only had a short time left to image so only got two images. Next time out I should be able to get a lot more.

Current Equipment


©2006 Richard Murray


This is my latest equipment configuration. The 80mm refractor on top which I just received in the mail is a William Optics Megrez Super APO which I'll be using for widefield imaging and to autoguide with. My main imaging instrument is an ATK-16hr which is attached to the APO. And of course my trusty LX90 SCT sits below the refractor.

Despite the somewhat awkward appearance of this setup it actually is very stable in all the positions I'm likely to encounter during imaging.

Oh and the toy robots in the background were really enthused when I first started to set everything up but they seem to have lost interest now. :>)

IC410 Tadpole Nebula



©2006 Richard Murray

Techno Stuff: 1/17/07 LX90 SCT ATK-16hr, Ha Filter, 1 x 500 secs, autoguided, no darks or flats, Binning 2x2, Processed Photoshop CS2, Adobe Lightroom, PixInsight, Image Analyzer

Notes: Mag 7.5, Size 11' Focus Star: Capella Reference Star: Iota SAO 57522

The bottom image was processed using a minimum and hipass filter technique in Photoshop CS2 (see Jellyfish Nebula image dated March 18, 2007 for details)

Milky Way From Cygnus to Cassiopeia


©2006 Richard Murray


©2006 Richard Murray

Techno Stuff: 10/29/06 ATK-16hr coupled to Minolta 28mm Lens at F/2.8 piggybacked on LX90 8" SCT, Ha Filter, 5 x 1800 secs, autoguided, darks applied, Binning 1x1, Processed in Registax 3, Photoshop CS2, PixInsight

Notes: This is a straight imaging run up the Milky Way from the constellation Cygnus all the way to Cassiopeia; a distance of about 5500 light years. Each panel of the mosaic (5 in all) is an exposure of 30 minutes using an Halpha filter. Each frame is angled to the right because of the earths rotation.

IC2118 Witchhead Nebula

©2006 Richard Murray

Techno Stuff: 12/19/06 ATK-16hr coupled to Minolta 140mm Telephoto Lens at F/5.6 piggybacked on LX90 8" SCT, Ha Filter, 5 x 1800 secs, autoguided, darks applied, Binning 2x2, Processed in Registax 3, Photoshop CS2, PixInsight

Notes: This is a faint reflection nebula which derives its glow from the large 0.1 magnitude star Rigel which is just outside the field of view to the left. Rigel is part of the Orion Constellation. Notice the witches head complete with hair and a star for an earring.

The second image was processed in the beta version of Adobe Lightroom. Thanks Dan!

Voyage to the Horsehead Nebula


©2006 Richard Murray

Notes: This is a gif animation of several images I took over the past several months with my Atk 16hr ccd imager and different camera lenses. The last frame was taken using my 8" SCT. To the top left of the Horsehead is the Flame Nebula.

Rosetta and Cone Nebula Complex


©2006 Richard Murray

Techno Stuff: 10/26/06 ATK-16hr coupled to Minolta 35mm Lens at F/5.6 piggybacked on LX90 8" SCT, Ha Filter, 2 x 1200 secs, autoguided, darks applied, Binning 1x1, Processed in Registax 3, Photoshop CS2, PixInsight

Notes: This is a wide field image of the Rosette Nebula (bottom right), the Monoceros Loop (a supernova remnant which covers half the image and embeds itself into the Rosette) and the Cone Nebula located at top center.

Lying just outside of the field of view to the bottom right of the Rosette is Barnard's Loop also a suspected supernova remnant which is part of the Horsehead and Orion Nebula region.
