From: Tom Hoffelder Subject: Marathon Report Hello Hartmut! This is my report on a 2009 Messier Marathon that was held in Tolland CT on the night of March 24th/25th. The participants were Dick Parker, Julian Shull, Charles Wilson and myself. We also had some friends, neighbors and even a wife (mine) visiting us throughout more than half the night. Since all were from this state, maybe we should call it the first annual All Connecticut Messier Marathon? Regardless of the marathon name, Dick used his homemade 8 inch f/8 Newtonian, which was his first scope, built during his summer break between high school and college 45 years ago. A number of improvements have been made to the scope, such as an optical window instead of a spider, but the mirror has its original figure. Dick has made many mirrors/telescopes since, his most recent being a beautiful 16 inch f/17 classical Cassegrain which was a big winner at Stellafane last year. He has also been conducting a winter mirror-making workshop in his basement where 88 mirrors have been finished in the last 10 years. (http://mirrorworkshop.mtbparker.com/index.html) Julian and Charles used Julian's 10 inch f/5.2 Dobsonian, which Julian made, including the mirror in Dick's workshop. I used my wife's 8" f/6 Newtonian (which is not homemade), but for the fun of it I did set up my 16 inch f/6 Dob, which I did make (yet another mirror finished in Dick's workshop), for looking at such things as M42, Comet Lulin, M13, Jupiter's Ghost and NGC 5907. The best may have been the field that easily showed M84 and 86 and the other seven nearby galaxies in a single view. Dick and I, having equatorially mounted scopes, both used my right angle sweep coordinates from nearby stars, while Julian utilized the conventional star hopping method of object location. (No go-to's allowed here!) I have attached some photos showing the scopes and participants. The first includes Dick's and Julian's scopes, with (from left to right) a neighbor, Dick, Charles and Julian. The second shows my scopes, with the guys in the background, and I'm on the right in the third shot. I have also included a photo of Dick with his 16 inch Cass, because it is such an awesome scope! Running a marathon in Connecticut is never an easy thing. It is usually cold and this year was no exception, the temperature being in the low 20's all night. You may be able to tell that from the photos, which were taken before the marathon started. (Luckily there was no wind; the night before had wind chills of near zero!) The state being all hills and trees and people makes it almost impossible to find a dark sky with good horizons. We chose a site that was better than most in regard to those two criteria, but it was very near a river (meaning high humidity) and only 400 feet above sea level, both of which definitely limited our results. Now, finally, to those results. None of us saw M74 or 77 in the evening. In the morning, we all missed M2, 30, 55, 72 and 73. Julian and I also did not find 54 or 75, plus Julian did not find 83, 102 or 15, but he did see them in other scopes. Therefore, the final count, for objects found, was Dick 103, Tom 101 and Julian 98, which is quite respectable considering the conditions, and especially for Julian since this was his first Marathon. Hoping all is well with you, Tom Hoffelder
