Moon, Venus and Jupiter from Hawaii

Posted By Roland Christen
Hi all,

We had excellent conditions for the conjunction of these three, and along with the clouds it made for some interesting images. This first one is just after sunset.

Horsehead Mosaic

Posted By Roland Christen
I am reposting this here, this image is super nice:

This is a two frame hydrogen alpha mosaic of the Horsehead region of
Orion. I don't post here often, but my AP160 gets used remotely an
average of 10-12 nights a month. The AP160/U16M combo are a beautiful
match with the field flattener, perfect stars to the corners. The
AP1200GTO has done extremely well operating remotely.

Hope you like it.

30 Doradus

Posted By Roland Christen
Hi group,

I just saw this incredible image from John Gleason posted on the AP Yahoo group. This image is too good to miss:

Rolando

Here's my latest work on 30 Doradus using our remote AP 155 EDIF and f/5 reducer/flattener from South Australia.

18 hours total exposure, with the FLI Proline 16803 OIII, HII, SII false color combine.

IC410 Tadpoles

Posted By Roland Christen
IC 410 is aptly named because last night it was ICY. Image was taken at -20F to -25F.

12" Mak Cass, STL11K camera 12 x 10 minute exposure in clear but poor seeing conditions.
