Nebula

New Images.

DSI-C	NGC7009 DSI with a .5 focal reducer on the 222mm f/7.2 Newtonian operating at f/3.6. 4 seconds X 91 frames. Captured as bmp's and stacked in Registax
DSI-C	7th December, 2005 222mm f/7.2 Newtonian with .5 focal reducer. DSI-c image of M42 the Great Orion Nebula. This is an image of 200 X4 second frames. Everything was set on auto except the Histogram. This I raised the white slider to 50,000 to stop the nebula from clipping. Save all uncombined as .bmp then stacked them in Registax and final tweaking of the Levels and Curves in the Gimp.
DSI-C	21st August, 2006. First night out since March because of light nights and the bad weather. M 27 The Dumb Bell Nebula. This was taken through very misty skies but I was not going to waste the night as I have not had a chance to look at the night sky since March this year. DSI-C image. 222 mm f/7.9. Atik 0.5 focal reducer. Atik IR filter. 46 X 30 secs captured in Envisage, stacked in ASIP in Windows. Fits files transfered over to Linux and the RGB combined in Cinepaint. L channel converted to png in Cinepaint and then combined in Gimp with the RGB png file.
DSI-C	21st August, 2006 M57 The Ring Nebula. Again the mist had gotten worse as can be seen here. DSI-C with Envisage used to capture 27 X 30 seconds. Stacked in ASIP in Windows. Fits files transfered over to Linux and RGB combined in Cinepaint. Again the L channel converted in Cinepaint to png and then the RGB and L channels combined in the Gimp. As can be seen I still have some more work to do on the guiding but the stars are starting to become rounder.
DSI-C	29th August, 2006 M15, Globular cluster in Pegasus. Mist again was present but I still wanted to work on the program GuideDog to tighten up the guiding. It would help too if the wind was not blowing. The stars are starting to look rounder but still more work is need. This image is 18 frames X 15 seconds.
DSI-C	29th August, 2006 M27, Dumb Bell Nebula in Vulpecula. This image is 25 frames X 15 seconds. Same night but still windy. Maybe better luck when the wind is not blowing so much.
DSI-C	29th August, 2006 M103, Open cluster in Cassiopia. This image is 13 frames X 15 seconds. Time here was around 01.00UT and the wind had started to drop but still the slightest breeze seems to cause the scope to rock about.
DSI-C	03rd September, 2006 M27, Dumb Bell Nebula in Vulpecula. This image is 60 frames X 15 seconds captured as fits.. The guiding is a bit better in this image but I still think I can tighten the guiding further. I am not sure what the bright area is at the top of this image. I did take darks and subtract them from the image as it was being captured in Envisage.
DSI-C	03rd September, 2006 M74 is a Spiral Galaxy in Pisces. This image did not turn out any good as I got far too much light pollution in the image. I have tried to remove as much of the light pollution as possible but I think the chip wells just got too saturated with the light bouncing off the mist. The galaxy was only just above the rooftops south of me when this was taken. This one I will have to do again when there is not so much mist or breeze about.
All 5 images were taken as best I could within the mounts PE and without guiding.	The next 5 images were all captured at the Kelling Heath starparty in Norfolk, UK After many weeks without seeing the stars it was a joy to have 5 straight nights clear although the first night was a traveling night so no images. I had a lot of trouble with the webcam and the guiding gear on this trip. I new it was all working before leaving for the couple of hundred mile trip but the gremlins followed us I think. My friend was playing with his setup all day and I was trying to capture some images of the Sun without success as the webcam was not being seen by the computer. Then the mount gave up the ghost as the power supply was not giving the mount power to run the motors so I took a long walk to get another power supply. Then when I got back the laptop was now not working. My friend came out of his Kendrick tent and asked had I touched any of the power points ? No says I, so he takes a look at the power supple under the caravan and the plug was just holding by the earth pin on the plug. Talk about a power supply being fickle !!! This took 4 days to track down as I thought the webcam was a gonner, then the mount.
DSI-C NGC7009	September 20th,2006 NGC7009 is 350 frames again at 1 second. Again this is a very bright object and I should have removed the .5 focal reducer to get better definition. I put this image through Registax this X2 enlargement and gave it slight Wavlets to bring out a little detail.
DSI-C M27	September 21st,2006 M27 is 41 frames of 10 seconds each. Here you can see the PE crept in and caused the stars to elongate. I think I am a little balder after this trip. I was determined to capture something even though the gremlins stopped me from guiding.
DSI-C Uranus	September 22nd,2006 Uranus is 200 frames at 1 second each. There were more frames on the Neptune and Uranus images but they were badly elongated so these frames were not used in the final images.
DSI-C Neptune	September 23rd, 2006 The last 2 images are the outer gas giants Neptune and Uranus. These two planets lay very low from my latitude in the thicker atmosphere and light pollution so I was surprised at how easy they were to capture although I am not too sure that the colours are correct. Neptune is 400 frames at 1 second.
DSI-C M1	September 23rd,2006 M1 is 105 frames of 10 seconds each. I used the 222mm f/7.9 Newtonian with the .5 focal reducer on all these images to help combat not guiding. This is a very bright object and the first time I processed the image it came out purplish in colour.
