Subject: [backbayastro] The Spaghetti Nebula - Tuckahoe Stargaze

 
After two stormy nights, featuring about 2” of rain, we were ready for clear skies at the Delmarva Stargazer’s Stargaze Star Party at Tuckahoe State Park in Maryland this weekend.  And we got it.  We had a beautiful clear day and evening on Saturday, April 13.  Amazingly, the night proved to be dry – I never turned on my dew heaters!  That’s rare for Tuckahoe, which sometimes has dew as heavy as rain, and standard procedure is to turn the heat on full burn very early.  And at midnight the SQM was showing about 21.0 – Not quite as dark skies as Coinjock, but not bad!  Combine that with cool, not cold, temps with little wind, decent seeing and transparency, and we had a beautiful night going.
 
At the top of my search objects list was Sh 2-240, also known as Simeis 147 and the Spaghetti Nebula.  This object is a very large (3 degrees) supernova remnant composed of wispy strands of star-stuff in the constellations Taurus and Auriga, just a few degrees from the Crab Nebula, M1.  And who knows how bright those wisps are going to be?  Early in the evening, with the crescent moon and Jupiter in the west, I didn’t think I had any chance at a Sharpless object – They are usually extremely faint and difficult to detect.  One good point: with a three-degree wide object, not much searching is required to find the field.
 
Despite the moon, I started without a filter at 114X (21 mm Ethos and Paracorr).  I suspected some nebulosity, but nothing was really apparent.  A UHC filter blocked the moonlight somewhat which made the nebula’s edges detectable, and this was confirmed by my intrepid observing companions at Tuckahoe, Kent Blackwell, Ray Moody and C. J. Wood.  I tried lower and higher powers, but I think the best view was with the OIII filter and the 21 mm.  With the OIII, the edges of the nebula wisps showed visible contrast against the black sky background.  Only a small part of the nebula was visible in any one view of course, but I was also surprised that I could detect several of the nebulous strands around this large object, not just one brightest part.  Given good conditions, smaller apertures should certainly be useful on this one.  Here’s more on Sh 2-240:

Our campsite at the Tuckahoe Equestrian Center had nice, low horizons to the south and west, so the setting crescent moon turned orange and was quite beautiful.

What a fantastic class this was!!

Many thanks to Jim and Chuck Jagow for leading the way by figuring out what materials we needed, buying them, showing us what to do and fixing mistakes along the way. All we had to do was show up with our scope, everything else was there waiting for us. What a great opportunity for club members, especially newer ones like myself. For the low, low price of $19 we all have now doubled our potential astronomy time with daytime viewing of our nearest star.

Plus it was a heck of a lot of fun.  We all had a great time talking astronomy, checking out gear and helping each other out along the way. As a bonus, Mr. Alcor, Bill Mclean, stopped by, and yes, he had cookies.

I had to leave for awhile to see my daughter swim. No problem as Courtney was so kind to fill me in on what I missed when I got back and even helped make up the lost time by helping me do some cutting and pasting.  Thanks also to Bob for lots of miscellaneous help & advice as well.

And don't let me forget to thank Jim for being such a great host. We had food, drinks, tools, power, supplies, you name it. In fact, between Jim, Chuck and Bob B. we had every tool you can imagine.  

Thanks again, guys!

All,
We had a very successful solar filter workshop this last Saturday. We got started around 10AM or so and finished up around 3or4. Everyone looked like they had fun and I'm sure they learned a few tips to use next time they need to make a filter. Attendees were Courtney, Chuck, Roy E. Paul Tartabini (Paul 1), Paul Shank (Paul 2), Mike Galvas, Dino and Mary, Bob B., with Bill Mclean (Bill 1) and Bill Holmes (Bill 2) helping out a bit. All in all it was a fun day and I look forward to the next workshop what ever that may be. I loaded some photos and I know others took a bunch so load them up.

Yuri Gagarin’s Controversial Landing

Today marks the anniversary of Yuri Gagarin's historic Vostok 1 flight. On April 12, 1961, the unknown Soviet Air Force pilot became the first man to orbit the Earth. But there's a controversy surrounding the flight that's been lost in moden retellings: to ensure Gagarin's flight would go down as history's first manned spaceflight, Soviet space officials issued a false statement about his landing. It's a bizarre twist, but there was a very brief moment when Gagarin was nearly stripped of the honour of being the first man in space.  Read more of this post

Spaceflight, broadly speaking, is divided into two camps: manned and unmanned or robotic flight. And people tend to fall into one camp or the other. Either you think manned flight is the only way forward or you see robotic missions as the best way to learn about the Universe around us. But what if the divide is less stark? It's possible that our future expansion through the Solar System will involve some cooperation between man and machine wherein the man stays firmly on the Earth.
I explored this idea a little in my first post for the London Institute of Physics' blog Physics Focus, where I am excited to say I will be a regular contributor!

Coincidentally, we had all just had Dee’s spaghetti for dinner Saturday night – I dunno, maybe that “chemical enhancement” helped.  With your sky and aperture, Ted, you should easily see it, even without Dee’s spaghetti.

Tuckahoe and Spaghetti?  I opened this expecting a quip about Dee’s culinary exploits. 

 

Sounds like another one of those nebulae (that I’ve come to associate with you, Roy) that lie somewhere between “ain’t no” and “I think I can see it” (with averted vision and chemical enhancement).    Another target for the bucket list. 

 

Glad Tuckahoe was fun and that you had at least the one good observing night.  I missed being able to go.  But, what is this dew thing you guys talk about?

Thanks for that link, Nick. I've seen some of Rich Jakiel's observations previously, and I think he's a good observer. Maybe I see why -- A 40 mm eyepiece with an f/3.9 scope provides an exit pupil over 10 mm! My, what big eyes he has!

Just kidding. But seeing all that with an overly large pupil does suggest that a smaller scope with a more reasonable exit pupil (that is, higher magnification, better matched to the eye) might do as well.

Quite a noteworthy achievement Roy! Thanks for sharing.

By the way, I found a webpage on this object you'll probably find interesting. This observer also used a 20-inch with O-III, but with lower power. It even includes a sketch!

Quite a noteworthy achievement Roy! Thanks for sharing.

By the way, I found a webpage on this object you'll probably find interesting. This observer also used a 20-inch with O-III, but with lower power. It even includes a sketch!

There have been many secretaries and late minutes are a common denominator. Let's be grateful this is not life and death. I am in two other organizations with volunteer officers and this is common with every one of them over decades.
I was secretary once for 2 years and guess what? I was late getting the minutes in. 

I read the last emails on this and see you've settled down, Nick. Thank you. This is the way it is. If we had paid officers you would have a valid point. 

Also, one way to keep abreast of what's happening is to attend meetings. The meetings are a lot of fun and have good fellowship- that means getting along in a friendly manner. Of course some of us live elsewhere or are simply living life. That's a reason to take it easy. Imagine if we were drummed out if we missed 2 meetings? I am in a city of Norfolk board like that. I missed 2 meetings, I was president. They eased up on the rules.

Lastly I am grateful we have a secretary at all, at the meetings he catches us up and reminds us of what we did in the past. Kevin, thank you for what you do. I thank Dale for stirring things up! That keeps us on our toes. But we must remember this is a volunteer organization and it is for fun, not feeding the hungry or saving lives.

That would be me, however I cannot post something I have not received. I got tired of sending requests EVERY month to our Secretary (who was reelected unopposed) to send me the minutes each month. This should be a given and it's not my job as webmaster to make sure our officers are doing there jobs; that is the job of the club President.

Thanks Dale, maybe another voice will finally get things rolling with our Secretary (or better yet get a replacement). It's not the first time we've had a 4-month backup on the minutes (August-December 2012). I raised a big fuss about this back in December to the officers.

George,

 I received the one about the date and replied to the group.

And Roger on the second one. Now.  If you have electronic materials, I can print some out for you. Just send them to me or tell me where they are.

I do notice that when I receive "group" emails from you, I receive them more than once some times as many as three, are you using some kind of list or something similar?  If so, I may be on it multiple times or the list is corrupt.

Here are my two replies.  I sent them to chuck@....  I don"t know why you didn't get them.  I am sending this reply to BOTH the group and to you.


Sent Monday, 4/8:

Chuck,

You didn't mention the DATE of the Cub Scout event at NWRP, but according to what I wrote in my calendar the night of the meeting, it is Saturday, 27 April.  What time do we need to be there?  

I have done the Cub Scout Astronomy Belt Loop many times, and i have a set of handouts I reproduce and give to the leaders for their Scouts.  We cover all the requirements for the Belt Loop award, and give them something to finish and take home. 

George

Sent Thursday, 4/11:

Yes, I can do the presentation at the campground.  I will have to reproduce the handouts for the Cub Scout Astronomy Belt Loop.  Do we know approximately how many Cubs there will be?
