    Gazing Doubles - Live Report

    Hi Mike. Very enjoyable thread. I was wondering which model Berlebach tripod is that?
  2. Philolaus certainly caught the eye with a shadow interrupting the rim and the mountain ridge running south from it making it appear as if it was an unravelling coil. Gassendi was terrific as well, with lots of floor detail. I also enjoyed Schiller, Hainzel, the bright ridge on the terminator side of Mare Humorum that starts with Liebig Scarp goes faint but then joins up with Gassendi, the top of an infilled crater near to Maestlin that was casting some jagged shadows onto Oceanus Procellarum, the Harbinger Mountains and J. Herschel. J. Herschel was fantastic, appearing like some gigantic motte and bailey. Disappointingly the clouds arrived just before Krieger was about to be revealed.

    Transporting telescopes

    My 8" reflector travels in the box it came in. I use the three polystyrene cradles underneath the tube and one over the mirror end. The tube rings and focuser prevent the use of the remaining two upper cradles that were originally holding the tube. I remove the finderscope and put it in the bottom of the box at the side of the tube. Due to the size of the box, I put the back seat down in the car and put the box into the boot. The secondary mirror collimation is fine travelling like this and I always check/tweak the primary mirror after setting up. I bought an aluminium case with foam insert for my 100mm refractor.

    The Atlas and Sky Guide Comparison Thread

    That's good of you to take the time to do the write up. Like the others I am also considering the Interstellarum Deep Sky guide. I already have the Interstellarum Deep Sky Atlas, which is my favourite for those who already have Turn Left At Orion. But perhaps more useful would be a tablet to run Sky Safari Pro. I don't have a smart phone and I can see that this software would be excellent for use at the eyepiece.

    Heads up ! Starcount !

    Just got back from Pont-Ar-Wysg in the Brecon Beacons where I counted 22 stars. The seeing was very poor with a lot of moisture in the atmosphere. High magnifications, above 106x, produced fuzzy, fast twinkling stars and the E and F stars of the Trapezium were nowhere to be seen. Unfortunately I have arrived back too late to look at the stars in Orion from my back garden. The constellation is low in the west in the murk now.
  6. I had a look at this double star, 15 Mon, last night and what a lovely sight it was. As you say, the 3 pairs of stars below it made a very pleasing view.

    Moon Filters for Visual Observation ?

    I used to use a Baader 0,9 ND-Filter to view the Moon. I still have the filter and it is more comfortable (brightness) to view the Moon through it. However, I stopped using it when one night looking at the craterlets in the crater Plato, I found that I could see more of them and the views were sharper without it. I suppose this comes down to the quality of the filter? Or is putting any filter in the light path likely to detract from the view?
  8. Excellent report Victor. Your view of the comet matches mine earlier this month in that there was no dense core to be seen. It was just one fuzzy patch.

    Messier list completed

    I know what you mean. I don't think that I will ever get to be at their level especially with the experience they have from the use of different equipment. I aim to have one reflector and one refractor. I intend my first refractor, which I bought 3 months ago, to be my only one. It was bought with old age in mind (mainly size and weight considerations). With regards to a reflector, I intend to get one with a larger aperture probably a 12" (Dobsonian mount) and that will be the end of my telescope purchases. That reflector will only be my second one.

    Messier list completed

    Those are good questions Dom @domstar. It can be good to review an achievement especially to strengthen memories. I have my atlases out in front of me now and I have realised that it would take quite a while to review all the Messier objects. I don't take notes and in the Messier list case I used to underline the objects at the back of Sky & Telescope's Pocket Star Atlas after each session. Therefore to answer your questions I am going to go with the objects that immediately spring to mind. Toughest to see for me was the Seashell Galaxy M83, low down in Hydra. It was also probably the one I found hardest to find. A special mention on hard to find has to go to the open cluster M29 in Cygnus. At the zenith when I was looking for it, it was a physical effort to get under the EQ5 mounted Newtonian and there were so many stars visible at the dark sky site that it was really difficult to find. First one without a famous name? I can't remember. Probably something like the globular cluster M56 in Lyra. I was using Turn Left At Orion as my observing guide when I started observing in August 2016 and this would have been well placed for me to view after looking at some famous ones like M13, the Ring Nebula M57 and The Dumbbell M27. The non famous ones that I found brilliant are the globular clusters in Ophiuchus, M10 and M12. They struck me as spectacular from a dark sky site and I remember thinking that they should be lauded more. They were really nice and grainy i.e. individual stars could be resolved. I think I read someone on Stargazers Lounge saying that they were in the 90's on their way to completing the Messier list. When I then counted the ones that I had seen it came to about 70. I realised that completing the list was a possibility especially as I had started to go to the Brecon Beacons to observe quite regularly. What about you Dom? How about answering those questions for my and others interest.

    Barnard's Loop Observers Analysis

    That's the area that I have been concentrating on following your and others suggestion.

    Barnard's Loop Observers Analysis

    Well Gerry @jetstream, I for one would be very interested to hear about the results of trying the Tak finderscope with the Astronomik Hb filter.
  13. While not particularly looking for them, I saw about 5 last night before midnight in a 2 hour period. They were quite far from their source with one spectacular one moving down through Orion.
  14. That sounds good Neil. I'll be interested to see what the more experienced observers recommend as I have been thinking about getting a tripod and mount for a grab and go set up. I'm sure you've read a bit about it already but with such a large amount written it can be difficult to sum up or bring to a decision point the best items. My sticking point so far has been deciding on a tripod that's light but also good at damping vibrations.

    Barnard's Loop Observers Analysis

    Just to add another technique in the attempt to observe Barnard's Loop. I was out again last night at my usual dark sky site in the Brecon Beacons when towards the end of my session and with thoughts turning to this nebula, it suddenly occurred to me, with my limited wide field view resources, that I could put the Hb filter in front of my finderscope. I was pleased to discover that the 1.25" filter fits perfectly into the recess at the front of the 6x30 Takahashi finderscope. I'm going to try this again the next time I'm under dark skies because there was a suggestion of some contrast changes at the location of Barnard's Loop. I need to improve my mental map of Barnard's Loop and study pictures of it that are hopefully more accurate than the hard line boundary drawn in the Interstellarum atlas.
