I have also posted on the FLI group and the way to go with large chip cameras is Pentax 67 lenses 2nd hand. They are cheap, they have enough backfocus for a filterwheel and a FLI PDF focuser (which I have and is a super electronic focuser but it does take up backfocus) and they also will cover a 16803 chip.

I am not sure what the specs are on L series glass. Are they designed for full frame sensors? It seems a lot of lenses now are designed for APS sized chips and they will not illuminate a 16803 chip nor a 11002 for that matter.


The 14-24mm Nikon is probably what I will get for terrestial and use the Proline with Pentax 67 lenses, filter wheel and pdf focuser for widefield autoguided on a mount. I am thinking a 45mm and a 150 or 200mm and ED glass.

I shoot all my images with the 5D Mark II. The best camera I've owned.

I shoot with the 17-40mm f/4L USM.

The Canon 1Ds Mark IV is not out yet. The 1D Mark IV is, which is the 1.3x crop factor. The 1Ds series are the full frame 35mm sensor (as is the 5D Mark II).

You could possibly pick up a 1Ds Mark III for about $7,000, if not less.

I imagine the 1Ds Mark IV will sell for between $12,000 and $17,000 upon initial release.

Gee who do they think they are FLI or something!!

The 1Ds seems a bit specialised and heavy. I think the 5D Mk11 is the go. Not sure how the Nikon D3 or similar stacks up against it. For asro I imagine Canon still has the noise and amp glow edge??

Many photographers are using that combo today and is a killer.

Yes it keeps coming up as the way to go.
