Hi All

On another site I belong to, this link came up and I thought it well worth posting. It is not often we get to see such a wide field. Posted with the authors permission.

G'day Radar and Draig,

I have scarce experience with EM200, but a shot with EF400mmF5.6 showed some periodic error in a 100% crop.

100% crop of the image. Stars are not round but reversed S.

The error was calculated as about 10 arcseconds/period.
We notice some near vertical movement due to my alignment error, too.

I must learn autoguiding soon.

Hi phoenix,

I love places mere three miles above our heads to view stars.

Hi all,

This is the 16minutes exposure photo before trimming, the longest exposure component in the HDR image. The right lower corner was near the ground and shows air effect.

"digital universe atlas" by Hyden planetarium, American Museum of Natural History in NY, US
I found this fantastic free atlas. Download, start milkyway.command, and turn on some buttons including mwVis (visible all-sky survey), mwCO (Carbon monoxide all-sky survey), mwFIR (the far-infrared all-sky survey), mwIRASc (the IRAS composite all-sky survey), and mwHa (the hydrogen-alpha all-sky survey). Please read "duguide.pdf" for more detail.

We can view many elements near the constellation Orion on the atlas.
