[AZ-Observing] Re: A Winter View of the Summer Milky Way

Hi Tom,

For me you have just made a very valuable observation.=20

" Note that Jeremy stopped the lens down from f/3.5 (its widest at 18mm) =
to f/7.1 in order to sharpen the stars and reduce the vignetting."

That should help some of my current issues with using the kit lens. I am =
currently "stuck" with the kit lens until I acquire better or find that =
the lens adapters available to use lenses from my Nikon FTN on the Canon =
XTi won't damage the electronics in some manner.=20

Thank you for the post,

Jimmy Ray

Jeremy's excellent image is all the more impressive when you read which =
lens he used: the 18-55mm Kit lens.  This is the lens that can be bought =
with Canon digital SLR cameras as a very inexpensive option.  Many =
advanced photographers "wouldn't be caught dead using this lens", but =
look at the results it is capable of producing.  Note that Jeremy =
stopped the lens down from f/3.5 (its widest at 18mm) to f/7.1 in order =
to sharpen the stars and reduce the vignetting.
