Great Hercules Cluster with spikes

Filed under: Photography and Art,Science — Chris Curtis @ 10:28

Although it is a nice, bright object, M13 is quite difficult to image. There are lots of small faint stars next to much brighter ones. As well as my usual processing with Maxim and Photoshop, I used the Starspikes Pro 2.0 plugin.
I do not like how Flickr has reprocessed this image, but it is convenient for publishing.

The Whale Galaxy

Filed under: Photography and Art,Science — Chris Curtis @ 14:35

The Whale Galaxy, originally uploaded by ThinkingCamera.

NGC 4631 in Canes Venatici. This is a very active galaxy about 25-30 Million Light Years away. The activity (the formation of many new suns) is probably a result of interaction with the small elliptical galaxy (NGC4627) close by and visible in the image and with another nearby galaxy.
We are seeing this galaxy edge on. It is about the same size as our own.

I went to some 60 second exposures for this. With my telescope having an alt-az mount, this means that the stars are no longer perfectly round, but there is more “depth” in the image. About 30 minutes of exposure in total – CPC800 Hyperstar telescope. Atik 320e Camera.

The Asteroid Juno

The Asteroid Juno a video by ThinkingCamera on Flickr.

This is a short video – a loop of two exposures – showing the Asteroid Juno moving against the stars. My first asteroid observation and image!
Each exposure was 15 seconds on the 320e camera on CPC800 with Hyperstar (f2). I “blinked” the two images in Maxim software and exported the video to Premiere Pro where I copied it to make a one-second loop repeated ten times. I added some simple titles too.

Leo Triplet

This is another attempt at this famous group of galaxies. This time I took 40 x 40 second exposures and processed the result slightly differently. Not too bad for a moonlit night with a little haze.

M3 short exposures

Filed under: Photography and Art,Science — Chris Curtis @ 23:20

M3 short exposures, originally uploaded by ThinkingCamera.

M3 – a magnificent globular cluster. This time, I took a different approach. Lots of short exposures.
This was 40 x 5 second exposures. Atik 320e camera on a CPC 800 telescope with Hyperstar (f2). Taken from a light polluted suburban garden. Processed with Maxim DL5 and Photoshop.
