Hi
With the forecast of rain for the next week in Perth I spent last night in my observatory trying to improve my skills. I remembered that I had a 1.25" UHC-S filter in my arsenal and decided to give it a try with the st2000xcm .... a 1.25" UV/IR filter was with the camera when I bought it so I attached that as well. I was a bit worried how things would turn out re coma without the 2" MPCC that I usually have in my imaging chain but found it not to be a major problem with the narrower field of view of the SBIG camera. The UHC-S filter helped a lot with the light pollution, it's the first time I have tried imaging with it as I couldn't fit it to my 350D and MPCC in my earlier efforts. I set to work from 9.30pm 'till 4.30am before cloud cover finished the night.
Anyway here are the results.
All single shot colour images taken with my SW 254mm F4.7 Newt, EQ6 Pro, ST2000XCM, 1.25" UV/IR_ UHC-S filters, self guided with CCDOps.
eta 600sec @ -12 degrees
m17 420 sec @ -12 degrees
m20 420sec @ -12 degrees
m8 600sec @ -12 degrees
m83 420sec @ -12 degrees
m104 420sec @ -12 degrees
m16 420 @ -12 degrees
p.s. I'm not real impressed with the galaxies but they were part of the session so are included as cropped images.
