300 observing sessions in 3 years is a hell of an accomplishment.
Huge congratulations. Now, we mere mortals want to know how you did it. I consider myself very very lucky if I get to observe once every two weeks, never mind once every 3 or 4 days. -ad ps. very nice drawing of eratosthenes. |

It turns out that the problem wasnt unique to posts made through
the web page. Both emails to oafs@... and posts through the web page were getting delayed up to about 8 hours. All posts do seem to be getting through though. If people want to post something they want seen in 8 hours, i suggest the do direct emails to oafs members. At least for this evening. Then again it may take several hours for this post to show up. -ad "Yahoo is pining for the fijords." |

Hi Bruce!... [snip of rest of excellent and thorough reply] ... PhotonBugThanks, Roland, and everyone else who responded to my original question. Am I safe in assuming that FLO is a bad place for bugs (seems to be low land, and surrounded by lots of cedar trees)? I think I'll definitely give the bug suit idea a try. I know that when I visit my brothers-in-law in Barry's Bay during bug season, I keep seeing tons of places advertising 'bug jackets' for sale. Maybe those are related to Attilla's bug suits. I'll pass the question by my bro's-in law and see if they have some advice too. |

The non-archived posts are all those being entered with yahoo's web page, rather than ones being emailed to oafs@....

300th Session! Log/Sketch Scan...
Made it so! - 300 Sessions in 3 years... Here is a scan on the May
1st/2001 page in my observing logbook. Matt guessed correctly that I would maybe want to make a Moon sketch, on the occasion of this 300th session. I had observed for one year before that with a 4.5" scope, but at that time, did not think to keep track of sessions in a logbook. Personally, I find it's really satisfying to keep an observing logbook. The crater in the sketch is called Eratosthenes after a Greek Mathematician who was the first to calculate the Earth's size. The crater is 58km in diameter and 3570 meters deep. I like the complex of ridges visible inside it as well as the prominent central peaks. I'm very glad to have met my goal with a few weeks to spare. Time for some new challenges. Perhaps more astrophotography? Or maybe some astrometrics? Just keeping the ball rolling... it's all in good fun. Photons Rule! Roland |

start that late last year, so maybe I have) so take the following with a grain of salt. But I have had normal levels of bug exposure in other circumstances. Personally, I ignore the little buggers. I used to get chewed on as much as anyone else and the skeeter bites itched just as much, but over the past few years things have gotten much better. I don't know if I have become less tasty to them, or if I just hang around with people who they find more tasty, or not. I know I don't flap my arms around a lot trying to kill them (even if they do deserve it) - maybe that changes the attractiveness. And this doesn't end at the time of exposure - I still get bit but the bites don't get as itchy as they used to. Again I don't know if I've become desensitized or if I'm just not scratching in the first place (or I seem to recall a claim that mosquitoes left to do their feeding will suck out most of the anti-coagulent that makes the bite itch, if I'm ignoring them - they get to finish)(but I'd rather not think too much about that). So I'm not going to claim that I know why I'm successful, but it seems to work (I know I've just cursed myself for the rest of the summer). Note that ignoring bugs is much easier if you're with someone who is being driven crazy by them. Note that on a trip to India last year I did use lots of Deet (I also didn't have a telescope) - though it turns out that the only skeeters were at the airport. I agree with Mike that most bugs won't stay active all night and if you put some repellent on areas that won't be touching your equipment (back of the neck springs to mind) and wash your hands thoroughly afterwards you should make it until bedtime for bugs. I've never tried one of the bug suits Attilla mentioned I've always worried that they'll make a muggy night worse - how bad are they really Attilla?

Re: More good news!
Excellent.
I suggest we plan a session to go out to the blairs, where we arrive in daylight. I suspect it would be wise to introduce ourselfs so the Blairs know who those dark figure scavorting at midnight in their feilds are. Btw, do the blairs own the crest of the hill. i.e. the actual former "Carty's mountain retreat" or have they bought one of the severerd parcels? It would be wise of use to know exactly which door to knock on. -ad |

I had always centred my secondary by centreing the corrector in the scope end casting. Recently I discovered that a direct measurement from the secondary holder to the end casting showed the secondary was 2-3 mm off centre! To date I have shimmed the corrector in position to get the secondary in the centre of the optical path. I had never imagined that there would be significant slop in the hole in the corrector that receives the secondary holder. I believe that a previous owner of my scope had tweaked and maladjusted my 2120 10" in every conceivable manner. Once the secondary was centred the views improved. Thanks again, Richard Jordan I determined two factors here. First, the secondary should be centered. Iis "optimized". The didn't tell me what that meant.

Beginner's Corner: Unsolved Bug Problem...
Hi Bruce!
Of Bugs and Astronomy... I have to say that the "bug" problem, as it relates to observing, is not one that I have yet been able to solve. There are various strategies that I've tried, but with relatively limited degrees of success. I'm still looking for a usable solution, so any working ideas from anyone would be greatly appreciated, I'm sure. One of the problems here is that success is fairly relative. If you get ten bites, is that failure or success? I guess it depends if whatever you chose to do about bugs reduced the number of bites substantially, but how are you to know that? Muskol is definitely too strong to use around optics. I remember first using some and having some plastic components on my equipment start to dissolve under my fingers. You can try to imagine, if you wantt to, what Muskol might do to multicoated optics. So, let me tell you what I presently do, and then I'll add a couple of ideas that I'd like to try out eventually. Bottom line: I know my solution is far from ideal, and that many observers would not use bug repellant at all near expensive optics. Can't blame them one bit. But, near my own equipment, I do use some bug repellant. I use it sparingly, and only in the minimum strength required to get the job done. The key concept for me is percentage of DEET in the bug spray or lotion. I have tfour types of bug repellant: from house-rated somke coils to deep woods spray repellant. For liquids, the DEET content ranges from something like 10% to 50%. Muskol, I think, is more like 90% DEET so I will use that only under very special circumstances and with my cheapest eyepieces. In my back yard, I will try two smoke coils first to see if that's enough. I prefer not to put these too close to the main optics. I also make sure to put on a dewshield at all times in bug season to prevent errant fingers, etc. Then, if the smoke doesn't work. I usually start with the low concentration DEET and work my way up. My ideal goal is to get no more than 5 bites per session, if possible. I guess I can stand that with minimum annoyance. Worst I got was 50 bites, one time. It's very much like going fishing in full bug season. Sometimes, you know right away that it's extremely "bad" as you are inhaling bugs just standing there, so you can skip a few steps and move directly to "red alert status". If I choose to use the strong stuff, I try to wipe the tips of my fingers so that they don't have much at all. I put some on my shoulders and back, so that I will stink of bug repellant without necessarily having some on my fingertips. At this point, I use my inexpensive Kelners and cheapo Plossls, and other stock eyepieces that came with the scope. Also, I try to have a "sting stick" available. This is kind of like a magic marker for bug bites. Once you're bitten, you touch the bite with this stick and the sting greatly reduces or goes away. Also the post-bite burn and itch gets diminished quite a bit. These sticks are available at any friendly Canadian Tire. There are all kinds of gagets supposedly available to bug removal, but up until now, these have proven either to be ineffective or too expensive or take too much time to work, to be practical for observing. Hopefully that can change eventually. As I said, you may find that many observers, especially those with more expensive optics, might opt not to use any of this goop at all. Can't say that I blame them one bit. But the result is that, for a few weeks each year, they either don't observe, or they maybe get eaten alive by bugs and end up with 50 to 80 bites per session. I don't like either of these options, so I do what I do. Maybe people need a cheapo bug scope for such occasions? Wear slightly thicker clothing, if possible. Otherwise, the darn bugs bite you right through your clothes! I wear sweat pant material for my legs at least. Thicker socks if it's not too warm. This simple idea reduces bites by quite a bit. All that's left vulnerable, if you do this right, are the hands and head. When I see inexperienced people come to observe at a "deep-woods session" wearing shorts and thin t-shirts during bug season... well... I guess I just feel really sorry for them. Finally, try to go where the bugs aren't, if possible. Avoid swamps and low-lying areas. But go for stone quarries and large parking lots ( for example the OAOG's Casselman site is excellent for that - there are 80% fewer bugs there, if you opt to observe from the center of that quarry. Why? No vegetation. ) All of these solutions or attempts at solutions are not ideal, but hopefully, they'll save you some time in that you won't have to use the trial and error method. Use bug juice at your own risk, though. I do so knowing the risks. So far, I am satisfied with the results. Testing on my scope reveals that the optics are still performing beyond the usual limits for such a telescope. So, I am a practical observer and not an ideal one. My rule #1 is "Observe". If there are obstacles to that, then try to deal with them as effectively as possible while still observing. Make it so! ;-) OTHER IDEAS I'D LIKE TO ADD OR TRY: - Bring "wipes" and leave them out in the open on a table. Wipe off my fingertips before touching any optics. You'd have to to this often as your fingers would tend to touch spray covered areas of your clothing or body. However, you'd greatly reduce the chance of transferring DEET to your optics, this way. - But a bug suit. I imagine these can be fairly warm. However, a few people I know (Attilla?) do wear a bug suit on occasion. I'm curious to purchase one of these for my anti-bug arsenal and see if I can't stay within my 5 bites/session range. - Modify a bug hat. I've had this idea for two years and can't seem to convince my dear Janice to use her sewing skills to make one. Start with a regular anti-bug hat with netting. Cut a hole for the eye(s). Either add a touch of velcro, or, add a king of 4" tube of netting that you let dangle. When it's time to observe, open the hatch. For me, the worst part of bugs is around your head and ears. Anyway, I'd like to try that soon if possible. I may even try my hacker hands at sewing to accomplish this. (I tried sewing once, to make an observing shawl out of black parachute cloth, and ended up sewing the darn thing to my pants!) ;-) There, that'll everything I have in that particular file. Hopefully, your question will stimulate more answers and ideas that might be helpful to observers everywhere! I hope this helps... All for now, PhotonBug |

Around my area the bugs seem to drop off sharply a couple hours after sunset so I just set up, go inside for a while and then come back later. Repellents could be quite bad for eyepieces so I tend not to use them or at least wash your hands after applying them to your neck and exposed skin. Some people's body chemestry just seems to attract them more than others sometimes (Attilla you're one of those lucky few arn't you?).

More good news!
Mike Wirths
Morning everyone,
Well the other night I phoned Mr & Mrs Blair, the couple that have land near Cardys Retreat, and got permission to use a lot of land they have which Mrs Blair claims has a very good south facing horizon. She also said it would be fine if we wanted to camp out after a long night of observing (this is a good idea! I've tried to drive home a few times after a Foymount session when dead tired) , apparently her daughter has an interest in Astronomy so I told her that I'd let them know when we would be coming so that they can come visit us. I'd like to take a trip out to the site in the next few days just to scout out the location, I'll take some pics when I go and post them at the OAFs site. This area rests in kind of a high plateau and has a elevation of around 1300-1600 feet and I would think that on a good night 7.0 + skies should be possible! The best way to get there I think would be to take 17 north and then take 511 (I think) west towards Calabogie. About 8km past Calabogie I take a right on Fergeson lake road (this is a windy dirt road --but its in good shape) this road leads toward Dacre but as I remember it (this was also the way i took to get to Foymount) you turn left at the stop sign instead of right which goes to Dacre. From there its about 6-8 km but I'll get complete directions when I go back on my scouting expedition. --clear skies! Mike W P.S. Congrats Roland! did you do session no. 300 last night? wow I wish I knew how many times I've been out (not disciplined enough for that ;>) |
