  1. Hi everybody, Does anyone use a Canon 40D here for imaging? Was curious to see how it compared with a Nikon D50 I also have so started off comparing dark frames using 1-30sec exposures ISO 1600, noise reduction OFF, sRGB colour space, JPEG (fine), lens cap ON and used at the same ambient temperature. What I immediately noticed was that the 40D shows (white) stuck pixels plus a lot of red and violet/blue lenticular-shaped regions. In comparison the Nikon D50 has few hot-pixels (very few) and none of these lenticular-shaped regions. Does anyone know what causes the latter? Attached is a (400%) re-sampled crop of one of these dark frames. Any help or pointers would be appreciated, thanks. Regards, David Randell

  3. It took me a while to set up and polar align my star adventurer and then frame and focus with backyard Eos. I set the backyard Eos in action and then nipped to my local for a couple of jars .....by the time I got home after an evening of conviviality and nice beer I was too ‘relaxed’ to sort out my dark frames.....so here is a stack of 30 X 180 seconds lights taken with my modified canon 40d with a stock 75/300mm lens set at 75mm, 30X180 seconds, f4.5, iso 1600, stacked in DSS then processed in photoshop and Lightroom. I always welcome comment and criticism..... .I know that this will benefit from some calibration frames and I imagine it would look nice processed in pixinsight.....am busy filling my piggy bank ?

    Harlem Planets

    From the album: Astrophotography

    This is an old photo shot with my 40D in 2012. This is from my fire escape in Harlem, Manhattan, March 2012 of the conjunction of Jupiter & Venus on the night of their closest approach when they were only 3 degrees apart in the sky. Just goes to show that you can do astrophotography even in the most light polluted of locations. Here is a celestial event as seen from "the city that never sleeps." Don't let you location get in the way of appreciating the night sky. ISO 1600 1/4s f/4.5 18mm
