Patch Springs Fire Photos from Sunday Night

Just in case some are interested here. Here are the shots I took both on the way out and at the observing site. You can see the smoke cloud is moving to the north and had no bearing on observing. Unless you waited for Ursa Major to get down near the horizon and you wanted to observe M81/82, M101 etc. Then the smoke would have interfered. Oh, forgot to mention. Mizar and Alcor were an easy visual split last light. I'm also working on a list that Brian Skill at Lowell keeps on visual naked eye observations. I posted the list on my Google Docs and you need the link to see it. It is here: Naked Eye Observing List https://docs.google.com/file/d/0Bz7NMp82LdUbVHpxSkx6R1VBRzQ/edit?usp=sharing I have seen M6, M7, M8, M11, M13, M15, M16, M17, M16, M17, M20, M24, M31, M33, M35, M36, (I haven't tried for M37 or M38), M41, M42, M44, M45, M46, M47, M48, M81 I am not sure 100% so I don't count it but others have seen it; NGC 1499 California Nebula with a UHC or H-Beta filter held to the eye.

Observing Sunday Night August 11th
by Jay Eads 12 Aug '13

12 Aug '13

Joe et al. **** Jorge and I had a very good night. The fire was well to the north and had zero impact on us. Breeze yesterday evening was blowing from the south so the smoke went that way as did the fire .As I was leaving Herriman and going out 73 I could see the smoke in the sky. By the time I went down the Faust Road you could see that the fire was well to the north and on a mountain. During the night if you looked that way you could see the glow from the fire as it worked down, but no biggie as only Ursa Major was that low and that is too low for me to want to observe something there. I’ll wait for spring on that. I worked a few galaxies in Bootes, some planetary nebula in Aquila and some objects in Cygnus (Sharpless 2-91,92 a SNR in Cygnus by Alberio; the Veil is about 7000 years old, this one is about 30000 years old but can be seen visually with an OIII filter and is easily photographed), Campbell’s Hydrogen and I wanted to sketch the Crescent but never got to it as I got distracted by some PN’s there. By 1:30a.m. the wind had come up and was gusting pretty good so around 2:00, I broke down the scope, got everything ready to go to bed then for an hour just watch a decent Perseid shower. Both Jorge and I had been watching them on and off and there were many small and quick ones, but there were many significant ones. The brightest Jorge saw as it streaked and broke into 3 pieces. However I think we both saw the brightest, a large one that streaked for a long time and then blew up literally over the Depot or Tooele. All in all, not an excellent night but it was good to very good. The Swan M17 was just terrific both without and with a filter on it. The filter really brought it out. Finally got red out of Campbell’s Hydrogen Star (a PN in Cygnus near Alberio). Slept from about 2:40 until 7:45a.m. then drove home and now am typing this up. If the wind had been less later I would have probably stayed up til 3:00 or 4:00a.m. observing. FYI, I sent this once but it did not post so I'll post it again.

Grilling King Question [WAS: Dark sky]
by John M. Craig 12 Aug '13

12 Aug '13

Gentlemen, gentlemen, Clearly you need a disinterested party to adjudicate this dispute. I am happy to volunteer to help you out in this way. I would propose a multi-session sitting with different meats: steak, ribs, chicken, and one alternative item chosen by each of the parties in the dispute. I would not require you to come to me--I'm happy to travel as necessary. I'm sure my wife would be glad to help and since two people's votes could be different, my adult daughter could join to complete a three-judge panel. We'll be happy to post results (including photographs of the samples or other types of evidence deemed appropriate). Feel free to contact me off the list to make arrangements. And may the best grill-meister win. John

Re: [Utah-astronomy] Perseids
by Jay Eads 12 Aug '13

Perseids were very active last night. I took breaks from observing for around 20 minutes and down on the Forest Land south of Vernon they were very evident. Many faint and quick ones came and you had to be watching. There were also many large and wonderful streaking ones leaving trails. We saw 5 or 6 that seemed to explode which was cool, one as a greenish color that did this. Jorge had his camera so I hope captured some and posts the image on the forums. By the way if you need quick access, go out to the Five Mile Pass area. No smoke as the fire is blowing northward and no impact from Five Mile Pass south. Less smoke also from the fire driving home this morning. This is much better than last year and I was at a decent site last year. Again as we all know, the darker the site, the more you see. When I was driving to the Vernon FR site, there was a group at Pit n Pole and I drove up to see if I knew them. I didn't and since it was crowded and Jorge and I had agreed on the Vernon FR site, I sent here. Looked like they would have had a good time but some were wearing shorts and tees. Remember if you go to the desert, it gets cool to cold at night.

Heading out tonight for what I hope is 3 days of observing out at the Vernon Forest Roads sites. Hope to see some good ones this weekend. Saw several last Friday that were really good.

Hello, I am heading out observing tonight, solo right now and that is fine. I know it is a Sunday and many work but it will be my last hurrah as I go back to teaching this week. So if your available and want to hook up let me know. Either Pit n Pole or Vernon is where I am leaning.

Image scale basics (WAS: Ring Nebula (M57) - Be prepared to squint)
by Chuck Hards 11 Aug '13

11 Aug '13

Here are a few illustrations and tables from Sam Brown's classic "All About Telescopes" that are useful tools for making sure the object you're imaging will be the size you want it in the frame. When the book was published, only film astrophotography was possible, but it's all directly applicable to digital imaging. Your imaging chip just takes the place of the film. The math is exactly the same. The first shows the 4 primary methods of telescope imaging. Note that a refractor is used in the illustrations, but the type of telescope is irrellevant. You can imagine the light cone coming from the objective at left to be from any type of telescope desired, the camera doesn't care. http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/Imagingsystemsil… The next table will tell you the actual size of the object you want to image on your chip or film, knowing your effective focal length. It's from the pre-metric days, so you'll have to convert inches to millimeters. This will tell you if you have sufficient image scale to show the object at a satisfactory size. You need to know the actual dimensions of your chip to know if the object will be too big or too small. http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/imagesizetable_z… This final table gives you the formulae to determine spacing with various systems. This will help you decide which commercial extenstion tubes, Barlows, adapters, etc., to order to suit your imaging system. http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/projectionarithm… Hope this is useful.
