The Owl Nebula - In Hydrogen Alpha and OIII
by Tyler Allred 08 Apr '09

08 Apr '09

Hi all. Thanks for all the nice comments about the article in the Tribune yesterday. I broke out the scope last night despite the bright moon. I decided to try a little narrowband imaging of the Owl Nebula, M97. I took lots of frames but had to throw away quite a few because of trailed stars. However, I did get 2 hours each of hydrogen alpha and OIII data, which I combined into a narrowband image. I used the OIII data for both the green and blue channels, and the Ha for the red channel. I was pleased that I managed to get just a hint of the larger outer shell, which is rarely imaged. Can you see it? I posted the photo on the SLAS gallery at: http://www.slas.us/gallery2/main.php?g2_itemId=1740 Click the small image for the full version. I also posted it to my website along with some interesting information, at: http://71.18.228.62/gpage8.html Click the thumbnail for a "clickable" full resolution version. I hope you like it! Cheers, Tyler _____________________________________________

If I have weird readers it's only because I'm pretty weird! Thanks for the nice note, Jim. I very much appreciate your comments. -- Joe --- On Wed, 4/8/09, Jim Gibson <jimgibson00(a)yahoo.com> wrote: From: Jim Gibson <jimgibson00(a)yahoo.com> Subject: Re: [Utah-astronomy] Jupiter's Age To: "Utah Astronomy" <utah-astronomy(a)mailman.xmission.com> Date: Wednesday, April 8, 2009, 6:04 AM Joe, Your article, The Age of Jupiter, helped me clear up a misunderstanding I had about protoplanetary disks. Years ago when I first read about protoplanetary disks and saw this picture http://www.seds.org/hst/OrionProplyds.html I failed to grasp that there was a star inside the dense pollywog nebula there. I thought it was a protoplanet on it’s way to star formation but the nearby star (not seen) was blasting away much of its material preventing it from completing it’s course to becoming a star and hence causing the pollywog formation. I see now that I missed the point because there was more going on than I realized. Had the pollywog been a round flat disk I may have seen what was really going on there. Funny, you write a nice article about Jupiter and I learn about pollywogs. You have some weird readers Joe.

Very impressive, Tyler. I don't believe I've seen the outer shell in any photo before, or if I did, it did not show up this well! Congrats, and of course, congrats to you and Sheena for the fine article. -- Joe --- On Tue, 4/7/09, Tyler Allred <tylerallred(a)earthlink.net> wrote: From: Tyler Allred <tylerallred(a)earthlink.net> Subject: [Utah-astronomy] The Owl Nebula - In Hydrogen Alpha and OIII To: utah-astronomy(a)mailman.xmission.com Date: Tuesday, April 7, 2009, 6:15 PM Hi all.

"Mission: Lunar Reconnaissance Orbiter/Lunar Crater Observation and Sensing Satellite (LRO/LCROSS) Launch Vehicle: Atlas V Launch Pad: Launch Complex 41, Cape Canaveral Air Force Station, Fla. Launch Date: No earlier than June 2, 2009 Launch Window: TBD The launch of LRO/LCROSS has been rescheduled to no earlier than June 2. This will enable sufficient time to be built back into the Atlas V processing schedule to support launch. The processing schedule became insufficient after the launch postponement of the Atlas V for the non-NASA mission currently on the launch pad. This week the LRO spacecraft team has been performing mission launch rehearsals, liftoff through lunar insertion. The solar arrays are planned for installation on April 8. The LCROSS spacecraft team is performing electrical testing." Source of information: George H. Diller Kennedy Space Center, Fla.

Congratulations, Tyler, for your beautiful Andromeda Galaxy photo in the Tribune! It brought the awesome beauty of space into people's home in a powerful way. Here's a beautiful view of Arches, and here's a positively stunning view from a Tremonton backyard. Wow! -- Joe

Tyler's photography

Congratulations on the two excellent Trib features! One question; the Trib article on Monday indicated stacked 20 min exposures. Is that correct, as I thought the exposures were shorter (2-5 min)? Steve
