Comet 17P/ Holmes

17P captured with Sony Handycam (camcorder) 28th October,  2007 2100 UT

Caputered this image with my Sony Handycam (CCDTR 748E) in Perseus.
5 minutes of capture and choosing the best 200 frames.   Stacked in Registax.  Final tweak in Gimp.
17P captured with SC3 webcam 31st October, 2007

Finally able to capture the comet with my 8 inch f/6 telescope.  Using Carsten's wxAstroCapture in Kubuntu Linux.  Captured with my SC3 1 sec X 300 frames.  Stacked in Registax running under Wine (in linux)  and final tweak in the Gimp
17P captured through 8 inch Newtonian 31st October, 2007 2038 UT

Here I used my DSI through my 8 inch f/6 with a 0.5 focal reducer.  This is 1 sec X 100 frames.  Captured and processed with Envisage
with final tweak in Gimp.  I found I had to cut the gain back to 30% otherwise the core was over saturated.
17P captured through 8 inch Newtonian 31st October, 2007 2038 UT

Same process as above but this time I have not gone so far with the stretching of the curves.  Is this a small tail developing ?
17P altered colour to match others seen on the web 31st October, 2007 2038 UT

I have no idea what the real colour of this comet is as I have seen red,  green,  blue, pink and yellow.
Most images I have seen seem to be a pink "cotton ball"  so here I have played with the colours in Gimp to match others seen on the web.
17P taken through a 135 lens 08th November,  2007  2130UT

The winds were very high tonight so I used a 135 mm lens on a static tripod to help combat wind buffeting.   Using 1 second exposures because of star trailing I captured 65 frames and let Envisage stack them.  Final curves and levels tweaked in Gimp.
17P mosaic 11th November,  2007

This mosaic was done with a 135 mm lens attached to my DSI.  I captured 89 frames of the top half of the comet  first then 89 frames of the bottom half. Each frame is 1 second.  Saved as fits and save all uncombined frames.  Processed in ASIP with a final tweak in Cinepaint in Linux.

8P Tuttle

8P Tuttle heading south 6th January,  2008

Using the EQ5 mount to track the comet.  DSI with a 135mm lens I used 15 second subs, 120 frames.  Over 30 mins the image started to build up but a lot of light pollution was also in the image so I had to blur a duplicate of the image and subtract this from the final image.  This tends to loose a bit of detail.   As can be seen from the star trailing the comet is heading south very fast.
