Possible clearing after 1am
Weather for Pinhey's looks bad bad bad.
However CMC's "cloud forcast for astronimical purposes" indicates a zone of very clear and dry air approaching that will probably arrive in perth/ottawa after 1am.
I'll put a dummy item into the OAFs calendar just so that well have a link to the right CMC forcast. Look for it on the main oafs page yahoo.groups.com/group/oafs
So how gonzo are people for more observing, given that most of us were clouded out last night?

Mike and I decided that we must abuse the rest of you with an observing report -- especially the ones who were planning to goto MikeW's last night but gave up because they didnt think it was clear.
I spent considerable time puzzling cloud forcast charts before I decide that It would cloud over around 9pm. For some strange reason I found myself driving the hour to perth anyway. In Carleton Place, i felt especially stupid since it became overcast. Then I saw a tiny patch of blue in the west, so I decide that I wanted to deliver some CDs to Mike anyway. Oh, and I could go look at that hilltop that was for sale (possible dark sky site) in Lanark. And also, I just felt like driving around in the dark. Hmm. And there was a gas station in Perth that often had cheap gas. Was that enough excuses? Hmm. Ah. Well. I've got too much gas in my tank? No. This is silly. I just decided to go. I didnt have a reason.
Prescient or just dumb luck. But the time I got to equuleus it was _clear_. Thats right it was clear last night folks and Mike and I had a hell of a good time.
For the early part of the evening we were joined by Brian (who had visited Mike's once before) trying out his new 4.5inch reflector. Mike also had a new pair of Zeiss eyepices with individual focusing rings on them for his binoviewer. (Hey people, Mike is _still_ winning.) We spent some time comparing eyepieces on Jupiterr. Seeing was just ok. But I was delighted that it was clear.
Then we prepared to watch ISS, Soyuz and the shuttle fly over. It didnt happen like we expected. Soyuz was supposed to precede ISS by 2 seconds and the shuttle was supposed to follow by about 12 seconds. Instead we saw one bright satellite rise and follow the path in the sky ordaned by www.heavens-above.com. Where the h*ll are the other two? Mike lent Brian his 19mm panoptic and Brian manged to catch the satellte in his scope for a second. He reported it to be double!.
After the first satellite has passed into earh's shadow and we still arguing over whether the shuttle could have already docked with ISS, Mike pointed out a second satellite. Then I thought "Of course. The shuttle is late. When does NASA do anything early?". THis time mike managed to catch a glimpse of the second satellite in his 18" starmater (operated manually). The remarable thing was that the binoviewer was still attached. Managed to get a glimse at 200 power. He reported that he definitely saw an airplane shape with perhaps a blue light at one end.
We concluded that the first satellite was ISS, with Soyuz still docked, and the second was the shuttle. The shuttle was behind schedule for its planned docking this morning at 8:36. I am now wondering if Mike saw the shuttle do an OMS burn to catch up. (seems unlikely to me. but its an observation worth repeating).
I was amazed that we could see so much, because I handnt expected it to be clear.
Then we settled down to a fine night of deep sky observing. M51 showed good detail. Not neally as good a the shockingly orgasmic night of april 13th, but plenty good enough to for a 'wow'.
Let's see. I'd like annoy you all with a list of all that we saw: m51, m13, darklanes in m13, ncg6207, m81 with spiral arms, m82, m94, m100, Roland's Face (the galaxy cluster around m84.) but not the 'dimple', the galaxy cluster 2 degrees away from Roland's Face that looks just like it but is missing the nose, mouth and ear, m104, m57, ic1296 (just barely detected), epsilon lyra, alberio, M3, eskimo, ngc4565 plus its faint companion. Plus lots more that I've forgotten (perhaps Mike can fill out the list).
But that was just the easy stuff.
We spent a fair amount of time observing Hickson 57. A very faint cluster of 14 to 15th magnitude galaxies each only about an arcminute across. It was _very_ difficult. After manovering the "trojan bunny" into position so we could sit more compforatbly at the eyepiece which was 9 feet above the floor, and concentrate on the ultra faint details, we both managed to see all 5 members of the cluster.
I was deglighted, especially considerign that I handnt expected it to be clear.
Mike manges to pull of a fine time every time he invites people out to equuleus, even to the point of arrange for the weather. Thanks Mike.
Oh, did i mention it was clear?

I made a reservation, under the name "danko", for 18:00 at the Little India cafe 828-2696.
Most people seem to know where it is, but WTH: Their address is 55 Wylie ave. Their are on a small street perpendicular to Carling opposite Coloseum 12 theaters. Their in a small, unnatractive strip mall with a convenience store, pizzeria and Indian convenience store. But the food is good.
If you decided you dont want dinner (say because you think it will clear for Pinheys) please delete you vote from the pool. At 5PM i will check the poll again and phone the restaraunt if we need to adjust the reservation.
Good food or clear skies.

As with most Pinheys Point RASC events, the clouds have definately rolled in. I see that one of Judith and my favourite restaurants is a shoe-in!!! It is a very small restaurant, and with this number of people, we would need a reservation. If this is a go, please advise me, and I would be happy to make it. Richard ps. I will have my cell on just in case 233-9081

Beginner's Corner: Messier Hunting
If you happen to be one of those persons who likes to see if they can find all the Messiers, or some other astro target challenge list, the following information, abstracted from my first year observing log, might come in handy.
Some Messiers, especially galaxies, are 5 times easier to find in a 6.0 mag sky than is a 5.0 sky. Some of the Virgo galaxies were barely detectable in my backyard, but were bright objects in a darker sky.
There are three four main strategies, in increasing order of difficculty, I used in locating both Messiers and best NGCs;
a) Use the telrad and place it in the correct location with relation to the visible ( up to mag 6.0 )stars.
b) Use a finderscope and place the intersection of the crosshairs at the correct location with relation to the finderscope stars ( up to mag. 9.0)
c) Use the finderscope again, but this time locating a star that is either on the same DEC or RA line. You need to calculate the actual field of view of your eyepiece and then move, while looking into the eyepiece, towards your target the correct number of fields of view - good polar alignment matters here. Often, the target in question comes somewhere into an eyepiece with a wide field of view.
d) When all else failed, I printed out a 3 degree by 3 degree, mag 13.0 map of the stars in area, orienting them for my SCT mirror-reverse view. Then I would match the star patterns in the eyepiece and would star-hop in the eyepiece towards my target. Sometimes, I could confirm the location with absolute certainty, but could not see anything there due to sky conditions. ( You can easily purchase these in a binder already made for Messiers and best NGCs ). Confirming loose open clusters is a breeze with these maps too.
Of course, you could use digital setting circles or a GOTO and save yourself the trouble of finding these things. But like many others, I preferred to learn the sky a bit first, and then later, will eventually get these very useful tools.
For the faint and small planetary nebulae, note that with a wide view eyepiece you may sometimes be incapable of dectecting these, as they look like tiny blueish stars. However, with a mag 13 map you can find it, or, if you have an OIII filter, you can do the flik test. Just slip the OIII filter in front of the ep. If the P.N. is there, all the other stars will dim cosiderably, but not the P.N. -- it sticks out like a sore thumb! You can then centre it and magnify to see the shape of the PN.
Finally, finding and identifying the Virgo galaxies, I remember, looked like a daunting task on the map. But I spent a few minutes each day planning my stategy for a few weeks. When I finally got out there, I was able to do 15 galaxies in about 5 minutes. After proving to myself that I could find them, I returned to each one slowly, and enjoyed the view.
Have fun hunting!

Excuse honourable Attilla, but I believe you are wrong. So sorry!! Judith and I have a favourite restaurant. It happens to be Thai, and it happens to be in the West End!!!! It is the "Chophyra" on Carling. Fantastic Thai food. JMHO. Richard

I'll be going out to FLO this evening - expecting to arrive about 21:30. Hopefully the clouds will arrive sometime after that.
Be there or be square. Rick

Re: Friday night observing

Hello all,
As it is uncertain if the weather will hold tonight (my last check seemed to show clouds moving in around midnight or 1am), I will be heading out to FLO tonight instead of Mikes. Thanks very Much though Mike!!
I wish you all clear skies, at whatever site you are using,
Matt (and the amazing jumping hat) Weeks

He'll be staying out in the area for dinner and then going to Mike's. . . sigh. I had to work today, so was not able to go with him. Your offer was most generous -- although I know our fellow OAFs would have been even more pleased if the Naglers were to have been enjoyed in your company. The way the forecast's looking for Saturday, we'll probably see you at dinner tomorrow. If it clears up, we'll look forward to seeing the Naglers . . . er, I mean you, at Pinhey's. ;-) Jan

Tonights excellent transparency mignt not last long
CMC's "cloud forcast for astronomical purposes" page has been corrupted. It caused the OAFs SKY events list to display the wrong CMC forecast image. Now it look like this image applies for 20:00 tonight:
and this one for 23:00
The images predict that it will cloud over before 11pm.
Sites east of ottawa will have slightly more observing time.
Crap.

I'm thinking I may have to miss out tonight at Equuleus. Considering how hard it was to get out of bed this morning I might fall asleep on the way there (never mind coming back). If anyone is going approximately past my place on the way out (Roland perhaps?) and would like to take the Naglers out give me a call (it may be necessary to pry my fingers off the case).

Re: for Al Seaman re: FLO
r.prevost@... wrote: Just wondering Al...
If an RASC member has a visiting family friend, or, an interested amateur astronomer who might wish to "visit" FLO, but accompanied by that RASC member, if that considered OK?
I couldn't see any info on that, posted on the RASC site, but if memory serves, I think that in the past, RASC members could bring a "guest" to FLO, as long as this was not "abused". Just wondering if you might possibly know the RASC's approach on this?
Yes, that is all correct. None of this is spelled out in rigorous detail, and I for one would not want to see FLO tied up in reams of written regulations. Common sense says we do want to protect the site from unwelcome people bent on vandalism or dumping trash. The logical limitation is thus to restrict access to FLO to RASC-Ottawa members. Those members are always welcome to bring guests with them as long as they keep track of the guests and keep them out of harms way (like sticking their fingers in the roof mechanism as it comes off), and keep them from doing something that might damage the equipment. So bottom line; RASC members welcome and supervised guests welcome. Cheers - Al

At Rob's request, I have created a poll so we can pick a restarant. At Jan's request, I have added a few west-end Indian restaraunts. But sorry, Jan, the only _good_ Thai places that I know of are nowhere near the west end.
The idea is to have dinner with oafs _only_ if its cloudy saturday evening. If its clear, most people will skip dinner and go directly to Pinhey's point.
So I suggest that people vote now, assuming it will be cloudy Saturday. (a pretty safe bet.) Saturday noon, I will phone the restarant with the most votes and make a reservation for everyone who voted.
I also suggest that at 5pm, people decide if they are going to skip dinner because they are going directly to pinheys point (or have any other reason to bail). If you decide to skip dinner, please delete your vote. A little after 5pm, I will check the votes again and advise the restarant to adjust the reservation (to zero if necessary). The reservation will be under the secret code name "danko".
Oh, and if you are extra people (who didnt get a chance to vote), email me attilla.danko@... with the number.
Clear skies xor food with astronmy friends.
