Wonderful? I don't know. This is Canon's own advertising, on their home website, trying to tempt us to buy a 20Da, right? So with a marketing budget that big, surely they're going to pull out the stops, get the absolute best results out there, to tempt us to splash out our cash on their 20Da and EF-L USM lenses?

Here's what I see in that image...
- screaming lateral colour around the stars...so much for the EF-L lens!
- double stars in the corners from a tracking jump, & field rotation pretty much everywhere...so much for showing us their best shot!
- where's the rich crimson nebulosity?... so much for the "enhanced" deep red throughput for astrophotography!

Subject: [APML] Canon D20a pictures

Hi all,
on Canon site have been uploaded some pictures made with the new Canon D20a digital "astrocamera". They seem to be little noisy, but it could be a little challenge trying to process them. Anybody is interested in? I'll try...
