Well, I sold my D60 and I have decided to change to Nikon for the next Digital SLR. Since I am taking a break from astronomy, the awesome low light performance of the Canon cameras isn't my top priority anymore. So I am selling off all my Canon accessories. Thanks for looking!
Sigma 75-300mm f/4.5~5.6 Autofocus APO Zoom Lens ($140 Shipped)
Simply the best zoom lens for astrophotography and wildlife that I have ever owned. Excellent APO performance for pinpoint stars and perfect color reproduction. Fast and quiet autofocus even with difficult subjects. The zoom is buttery smooth but holds its position even through several hours of late night piggyback shooting. You want this lens. Has front and rear lens covers.
$140 shipped in the USA. I prefer paypal but will also take money orders.
