M42 under Ha with mono converted Nikon D50 new
      #5611161 - 01/07/13 11:31 PM Attachment (34 downloads)

Just a quick test of a mono converted Nikon D50 under terrible sky conditions, windy with hazy clouds but the clearest night I've seen in Toronto for the past THREE months!

no darks, no flats, just stacking and some curves in PS

A equivalent image with a conventional Bayer color DSLR would only get a signal in the red channel and have only 1/3 the resolution and scale plus show much less nebulosity in 30 minutes.

Awesome!

Who did the conversion for you? I have been giving it some serious thought to try it out myself

this time with dark subtraction, better noise control.

Finally a decently clear, crisp night over Toronto and a chance to test the monofied Nikon D90. Check out the Ha cloud detail after only one hour of integration and ridiculously short subs. The monochrome sensored DSLR is an ideal tool for the urban narrowband imager!
