NGC 7000 North American Nebula

I've been trying to expand my astrophotography work to wide field images using normal camera lenses. I have the usual 18, 28 and 50 mm lenses for Canon DSLRs but was looking for something with a little more magnification to it. To that goal I dug out my 44 year old Vivitar 70-210 with macro lens. it was original made for a Minolta camera mount. This old lens has some evidence of crazing in its optical coatings but I wanted to see what it might offer in focal length. I placed a Canon lens mount adapter on it and after manually setting the f-stop to f/5.6 pointed it at NGC 7000, the North American Nebula. The attached image is a composite of seven frames shot at ISO 800 and 3200 for a total exposure time of approximately 26 minutes. Needless to say, I'm quite pleased with the performance of this old lens.
