About this image

The exposure and number of frames used to generate this pic are a guess as I lost the original data (there was much whining and gnashing of teeth). However, it was a clear night, I had a new scope and I fancied just having a play rather than imaging something useful.

NGC2903 was one of the first galaxies I imaged with a homebrew CCD in 1994. It had the virtue (like NGC3184) of being near a brightish star. The frame was so small then I could only just get the main body of the galaxy on the chip, the Dec drift carried it off the chip in about 40 minutes and the CCD noise level was probably 50x bigger. I think I managed 9 untrailled images. So when I got HII regions that I could see in the Burnham's guide I was entirely chuffed.

That was then. The technology has moved on a lot so I instead get a fairly decent pic these days with little difficulty. I know colour can add a lot, but I am content with monochrome thanks.

Still odd that Messier and chum missed it. Too distracted by Virgo?

And yes, I know the collimation was way off!
