  1. There is a fairly long thread on this scope over at CN. Have a look at it. You can check yourself by looking at the mount specs. The Bresser Messier AR102xs weighs 2.8 Kg and is 43 cm long (without diagonal and eyepiece). It mounts using a Vixen dovetail.
  2. Nice family! I just wonder what is the main reason you got the new ones, as 16x80 is possibly not that a huge step from 15x70. Is the ability to mount them? Just curious
  3. I am taking the liberty of using this older thread with the same topic to alert those of you who enjoy nighttime darkness at this time of the year that SS Cyg is right now in outburst!
  4. Oh yes! The old school is fun indeed ! Just a caveat: planetarium software and GoTo might help you find things faster, if you are impatient choose GoTo and avoid calculating yourself
  5. Yes, that's the easy route, and that's all fine. But, looking from some other perspective, star hopping gives you the pride and joy of learning the sky. Just a reflection
  6. I also believe it is a very good scope for the money. Obviously, compromises were made but overall I have a good impression. The one thing I believe can be questioned is why manufacturers add arguably low value items to these scopes, like a flimsy finderscope, a cheap eyepiece or plastic diagonal. I believe it is sounder practice to invest in few valuable and meaningful items, optics and mechanics, rather than adding things that will not be used or soon replaced. In this case, for example, I would rather not paid for that finderscope and that eyepiece. Just a reflection.
  7. It is really very good, solid and nice quality. As some user over in CN wrote, a possibly useful upgrade would be a microfocuser (10x). The only detail I was a bit weary about was that when moving the scope manually using the Porta II mount I tended to grab on the scope side of the focuser, loosening it a bit, having to adjust it at least twice I cannot ascribe this to a build problem though, but probably only to my own clumsiness.
  8. Hello SGL'ers I have long considered different options for a capable yet affordable combo that will enable problem-free train and air travel, as well as comfortable bicycle and backpacking tours. I recently saw that this new scope has become available and got interested. As it is a new product there is not much information around, with the exception of a lengthy thread in a German forum and one in CN (where I also posted more or less the same content shown below, except for the photos, that are only posted here - hope you do not mind). I received the scope yesterday. The telescope is indeed small (43 cm without diagonal, compare with normal keyboard below) and relatively light (~2.8 kg). It came well packaged. The important parts (focuser, dovetail, lens?) are of good quality, with the exception of the diagonal which obviously needs upgrading to something more serious. Other parts are less qualitative (finder scope, the finder scope plastic holder, the included 26 mm plössl eyepiece) but I do not worry about these since I will not be using a finder scope and have other, better eyepieces. The package included two extensions as well, I assume for photographic use. Tests made during daylight using the supplied 26 mm plössl (giving 17.7 x) showed very nice images without any striking problems. The combination of scope, diagonal and EP apparently inverts horizontally but not vertically, so the system works well for terrestrial targets as birds. I also setup up at "night" to do some tests but these results are possibly not very representative since it does not get dark here in this time of the year (only civil dark with the Sun reaching a minimum elevation of 8 degrees below the horizon). A street lamp about 50 m away showed a clear blue rim on one side. Not terribly annoying, but it was there. Same with Arcturus, which showed a red tint, or flare that shouldn't be there. Dimmer stars looked OK, but as said above, the sky was too bright and I could barely detect stars of mag 7, even with this scope. I could not test with Moon or Jupiter, as these were hidden behind the trees. I used the ES 82/8.8 mm eyepiece for these tests. I also acquired a Vixen Porta II Altaz mount on an APP-TL130 tripod for use with it. The mount is simply excellent, and the tripod is sturdy and very light, a highly recommendable pair! My first impression is that this telescope is great value for the money and that the system will work perfectly for my intended purpose. The fact that bright stars, and surely Moon and planets, show obvious chromatic aberration is not a problem for me. As a visual observer, mostly interested in variable stars and DSO's, I believe this scope and mount will provide a good combo for me. For all other things I can always use my 200 f/5 Newtonian. I will write a longer review when I do some serious night testing. That will be when it actually gets dark again, namely in two months
  9. The bugs have awakened here and the Sun refuses to sink to decent altitudes below the horizon. Last night it was only 9.2° below horizon at midnight. In this bright civil darkness, nautical twilight, and amidst some stubborn high altitude clouds, I was able to spot the long period variable star R Serpentis with 15x70 binocular. I estimated it at mag 7.7 ± 0.2. A simple, short and unpretentious session. Not bad for being 27 May at 60°N!
  10. Wow! That is an order of magnitude smaller than the usually quoted maximum visual acuity of 0.1 mag. Very neat!
  11. Excellent and very interesting, Dave. What is the error margin of your measurements? Just curious.
  12. Late May and Sun barely 9.8 degrees below horizon at midnight, with attending twilight on top of the light pollution. Hopeless? Not at all! It was clear and calm, and with staggering +8°C it was mandatory to get out. Stars up to mag 3 were visible with effortless naked eye, mag 4 with a bit of effort. Picked my 15x70 binos and sat in the garden. Spotted R CrB and could estimate it at mag 7.6. The mag 7.4 star to the west was very clear, as was the 8.1. one to the west of comp 7.4. Missed R Leo behind the forest and looked in vain for comet C/2015 V2 Johnson, but M13 and Y CVn provided additional joys in this balmy summer night. Clearly, one can observe interesting (and bright) variable stars even in the midst of northern summer twilight. A joy I will make sure to appreciate often this summer. Cheers!
  13. Ouch... I posted with the phone, it often leads to something weird. I will edit later using a real computer.
  14. Here is a good article about comet Johnson in S&T, with their usually useful chart: http://www.skyandtelescope.com/observing/comet-johnson-makes-a-splendid-sprint-through-bootes/ Hope everyone gets to see it. I will try tonight, in spite the northern twlight. I have to get out anyway out of self respect since it is clear!
  15. Yes! We humans are naturally bad at appreciating angles. This is something we have to learn and train if we wish to become accomplished at. I learned this from the work of Cleveland in the 80's about graphic perception and the design of plots and figures for scientific work. I do not have the reference at hand now but will pick it up later today. * the reference is: Graphical Perception and Graphical Methods for Analyzing Scientific Data. W.S. Cleveland and R. MCgill, Science, 229 (4176) 1985.
