Re: [APML] A few Canon 10D shots from this past new moon

Hi John,

Nice shots.  Your Rho Oph mosaic caught me eyes.  I believe
mosaic with DSLRs could be a very powerful way to produce
wide-field images.  Indeed, Japanese astrophotographers are
now regularly producing mosaic images with DSLRs.  Some
Japanese telescope retailers are selling focal plane mosaic 
devices for DSLRs.  With these devices, one can easily make
2x2 mosaics by shifting the camera in the focal plane without
changing the telescope pointing and without changing the guide 
star.  Vignetting correction and distortion correction also become 
easier or even unnecessary.

I feel that your lens shots are noisier than the FSQ106 shots.
Is there a reason?

Cheers,

Wei-Hao
