  1. I am bit late to this post. I would recommend any of these two, according to your wish of the book focusing only on the observational part: David Levy. Observing variable stars. A guide for the beginner. Gerry Good. Observing variable stars. In particular, David Levy's book can be found cheap used, specially the old version from 1989. The AAVSO's visual observing manual is also a good starting point. There was a discussion a while ago about books on variable stars over at CN. You might want to have a look there. Good luck!
  2. Hi, I just did nothing about this. I can certainly live with these small aberrations.
  3. These charts look very neat and useful. Which software did you use to plot them?
  4. Show us your set up in action at night.

    Indeed, it is often a bit of a challenge to share site between visual observers and astrophotographers, one that requires observance of some etiquette.
  5. R CrB again

    Hello variable star fellows! I have been away from this forum for a while, but not away from variable star observing! Yes, @SilverAstro, I have taken notice of R CrB and its wonderful peregrinations, and yes, darkness has finally made a lucky return to this northern lands (this coming weekend will be first astrodark at my place since mid May!). We are even having some unusually long streaks of good weather! The only down side is that I cannot see Coronae Borealis from my house these days, as it is well hidden behind a tall forest right behind my house. So no R or T CrB for me, at least as everyday treats. In any case I have made a lot of variable star observations these last three weeks (in nautical darkness): khi Cyg, T Her, X Oph, R Aql, U Cyg, T UMa, S UMa. I am also starting to think about a long-term visual observing program. I am now in my third year since I got the variable star bug and believe that my observations and estimates are good enough to share them to the wider community, so since a few weeks ago I started doing so via the AAVSO website (got an observer ID). You see, these are good times for variable star observing! Cheers!
  6. 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.
  7. Show Us Your Binoculars.

    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
  8. SS Cyg in outburst!

    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!
  9. How to find planets

    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
  10. How to find planets

    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
  11. 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.
  12. 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.
  13. 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
  14. 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!
  15. Wow! That is an order of magnitude smaller than the usually quoted maximum visual acuity of 0.1 mag. Very neat!
