I have a Coronado PST arriving this coming week and I'm considering getting a Meade DSI for imaging the Sun.

I am considering the DSI II or DSI pro (not II).

Trying to decide which will give better resolution - I am astounded by the images that Paul (1ponders) produces using a DMK and would like something approaching the sharpness he is able to achieve.

The II (colour ccd) has a 1/2" chip
- pixel count 437,600
- pixel size 8.3 x 8.6 microns.

The pro (mono ccd) has a 1/3" chip
- pixel count 250,00
- pixel size 9.6 x 7.5 micron.

I see the II has better software and cooling but is more complicated due to the filters (supplied in the price).

I read that you need an IR filter to go over the RGB filters and need to refocus as they aren't parfocal - perhaps just need refocussing when using the L filter as it blocks IR so no extra filter needed.

So, would they give similar resolutions, actually would the images be just as sharp taken with either camera?

Is it a lot of bother taking multiple shots with LRGB?

I haven't done any imaging before but I am really looking forward to using Registax or similar to enhance images. I think it would be fun & interesting.

Yes, I see the DSI II for sale here and I am considering it - a good price.

I am tending to favour the DSI II.
