This image was made with an Orion ShortTube 80, which is an achromat with a crown/flint doublet objective. The colors that I get from the AT72EDII are far less intense, but probably more realistic.RoryGhttps://www.blogger.com/profile/13200628155673456582noreply@blogger.comtag:blogger.com,1999:blog-3977859904854142487.post-27827062919187578802014-01-23T12:42:11.279-08:002014-01-23T12:42:11.279-08:00I want to go back and redo the Double Cluster with...I want to go back and redo the Double Cluster with the astrograph soon. It's been on my to-do list for a long time. This was just a quick-and-dirty imaging session. The focus wasn't even all that great. Plus, I was't using the computer at the time, so I was limited to 30-second exposures unless I opened and closed the shutter manually.<br /><br />I like the Horsehead and Flame because one can get impressive results with very little effort. Of course, quality improves proportionally with effort...RoryGhttps://www.blogger.com/profile/13200628155673456582noreply@blogger.comtag:blogger.com,1999:blog-3977859904854142487.post-83993932017959677022014-01-23T11:58:11.584-08:002014-01-23T11:58:11.584-08:00Spooky.

Like the Horsehead, too. Gotta love what a camera can help you see!Polaris Bhttps://www.blogger.com/profile/11572022039526168617noreply@blogger.com
