Very nice.

Love those tropical island shots - very appealing.

A hot looking boat.

Is Pentax *istD good for astrophotography ????

Posted By Greg Bradley

The digital camera astrophotography group on Yahoo would probably know.

Wow, you see detail right into the core!
I have an SBig 2000XM. Excuse my ignorance but can you stack and align images in CCDOPs?

Also can you do a colour combine using it?

I suppose I should read the manual more carefully. I have a number of images I have taken but haven't processed any. A little job for today!

The cold and hot pixel filters are in CCDSoft?

Hi Jeff,

That's really nice. It would be great to do a mosaic across the sky. I think to do that you would need to be on the tripod to get the camera at the right angles for each shot.

Perhaps go for 20 secs and take more to get more sharpness. Also on the digital group Pertti has done a great eval of various lens. Typically they perform sharpest one or two stops above their maximum, so perhaps F2 for this one at 20 secs and 10 of each spot in a series for a mosaic.

Also, if you have a fisheye lens you can get the whole sky in one hit. Peter Ward has posted a stunning Milky Way showing the lot in one go.

Its one of my future projects.

One other thing. ISO 3200 on the Canon I believe is no different to ISO 1600. Just from what I have gleaned from the Astro-digital group.

If your camera was modded you could get the same brightness on 20 seconds or less, maybe even 10 - 15.
