First Images with the Outback Cooler:





Bubble Nebula ( 5 Hour Exposure total)

I've attached a few recent pics from the DSI Pro II and my 300mm Nikon lens that probably could not have been done without the temp regulation of your cooler. The longest exposures was the Bubble Nebula (five hours of 30-min sub frames). The temp would have changed too much during these exposures to have effective dark frames. I hope this helps make the point.

Mel uses an SLR Lens mount to fit a Nikon 300mm lens to his DSI Pro II Camera. Pictured left. He has since upgraded to the Dingo version of the Outback. Impressive lens, just like his images.

M2, Globular Cluster in Aquarius

Tom King

First light for the Outback Cooler with the DSI Color imager. Images and darks captured at 68F/20C, regulated by the Outback Cooler. Ambient temperature was 93F/34C.

Noise in the individual exposures was almost negligible and none of the usual internally generated gradients seen in unprocessed DSI images were present. For the first time this summer, noise in the blue color channel was virtually non-existant, and did not have to be dealt with.

Globular clusters have always been difficult objects for me to render in presentable form. I have never really been able to determine why this is so. As a result, most all my attempts to image clusters have ended up in the binary trash can! Although not perfect, this M2 captured with the DSI Color running the Outback Cooler is in a class of it's own compared to earlier attempts. Click Below is my best previous attempt at M2 with the DSI Color.



Equipment: Meade LX90 203mm SCT @f/3.0 in Alt/Az, Meade Deep Sky Imager with Outback Cooler regulated at 68F/34C Settings: 16 x 21.2s, gain=100, offset=50, saved as Fits Raw

Processing: De-rotation and rgb color set in AS-IP. Debayered and Color split in Fitz (thanks Hillary!). Final processing of curves, color balancing and unsharp masking in Photoshop CS. Imported to Photoshop CS with Fits Liberator

This is the first true example photo taken with Steven Mogg's Outback Cooler. I did not shoot darks for this photo, I re-used the darks taken about 5 days ago with the camera cooled to the same temp I used during capture, 10C. Not having to take darks was GREAT!! I can't believe the lack of any noise at all while capturing the exposures. Even though I save to fits files I still like to check combine and see the image build on the screen, this photo is very very much like the image that was building, very little processing has been done to it. No color processing was performed. I'm still amazed that the DSI can perform like this under my 3~4 VLM skies with only 80mm of aperture!! I've also noticed that because the exposures come in so noise free the tiny stars show up in the background really well and they come in in their correct colors for the most part. The cooler is excellent!!.  by Matt Taylor 30 May 2005

I shot 2 really quick test photos last night at 10C, these were quick, down & dirty, very very little processing has been done and if I were shooting these for real I would have taken a LOT more exposures, so these are just to show off the cooling under way less than good conditions. I had wind, and an almost full moon to deal with so naturally I chose a really hard target like NGC6992.
