Into the Trap!

Unread post by WCGucfa » Tue Mar 13, 2007 9:32 pm

Hi Guys,

I've been trying to image the Trapezium, Theta 1 and also Theta 2 in the Orion Nebula for awhile with my "non-astro" camera with no luck. The problem was either seeing, wind (as it's very hard to take pictures on a small mount in the wind) or the fact I'm never sure what I'm doing anyway.
Last Sunday night the seeing was pretty steady so scintillation was minimal. I took a couple of test shots and ended up getting something.
The nebula photo was taken about a month ago. As you know the trap is always whited out without heavy processing, so I cut the exposure and zoomed in with the camera. Here are the results.
For the Trapezium: Camera- Sony DSC F707, 7sec. @ f/2.4 through a Scoptronix MaxView 40mm EP. My scope is an Orion 120mm, f8.3FL with dual axis drive.
The nebula was a 3-4 sec. exposure. All other settings are the same.
I started imaging/experimenting with this camera in order to photograph double stars and noticed it was far more sensitive. All my comets are shot with this through the scope. It's a limited, won't-knock-your-socks-off set-up but it's fun!
I've noticed I can reach 11th magnitude on longer exposures(25 seconds).
The short exposures typically reach 10th magnitude.
The Sony is 5 megapixels. Image shoot size 2560 x 1920. These shots have not been processed except for some cropping. Noise and color can be adjusted.

Bill

Bill very cool images. You are more motivated than me. 8) As i'm a rank novice at imaging I'll offer nothing on the the way of advice except, Good job! :D

You really captured a lot of nebulosity, looks great!

Hey, Thanks a lot guys. In reality it's everyone in the club who motivates me. Even though I don't have a lot of time to join you in your astronomical adventures, including a lot of meetings, your posts make me feel like I participated in everything you've done.

Funny thing about the pictures. I've filtered out the light pollution at times in the scope and at times in Photoshop, but I always go back to that weird sodium vapor streetlight background color, unprocessed. What could that possibly mean? Even the chromatic aberration looks cool to me.
Maybe I'm just so thankful something shows on the frame!

Thanks again for the feedback.

Two words about sodium vapor lights, sling shot....:)

Hi Bill,
I got some exposures of M42 recently with a Meade DSI Pro camera and my 5-inch ED refractor. I'll look them over again and if I can find one with good detail I'll add it to this post.
I visited Greg Stone on Tuesday evening and he showed me what his color CCD camera can do. I saw M42 displayed as a live capture on a small color monitor. It was awesome. The most detail came with exposures of 6 and then 12 second exposures. The Trapezium was over exposed at those settings but the detail and color in the gas cloud was really amazing. The camera was able to capture stars when clouds totally blocked our naked eye view. It was something to see! Greg wrote it up on his web site.
Clear skies,
Dan

P.S. This photo was taken on Nov. 18, 2006 with my Meade DSI Pro, no filters other than the IR. The camera was on my 5-inch ED refractor.

Hi Dan,

Since the last time I talked to you I've purchased a DSI Pro II with all the filters. Of course my Sony has distracted me from setting the pro up and using it.
Please post your results when you get a chance.
I'm building up my photo equipment arsenal for comet Enke in April.

Bill,
I posted (above posting) one of my M42 photos from last November. Not sure how much longer I'll be able to image this beauty. By the time it gets dark now Orion is to my southwest and heading for a big tree. :oops:
Clear skies,
Dan

Dan you got some fine detail in the structure and mottled nature of the nebula, very nice!
