  1. oh yes, if you split them with binos, time to enjoy your frac all the way... I guess you enjoy very good seeing conditions... I will try next time split Mizar A and Mizar B (14 arcseconds apart). EDIT: I just did the Mizar A-B split. Very clear. No way for the couples forming Mizar A, Mizar B, nor Alcor (yes, in total they are 6 stars).
  2. Very interesting, so with good seeing you can actually split the 4 main trapezium stars with a 20x80 bins.
  3. Hi guys, just finished a quick observation with my 15x85 binoculars. After enjoying some Messiers and NGCs, just scanned Lepus to spot R Leporis (the Hind's Crimson Star) to enjoy its red color. After that I pointed to the trapezium of M42. For my surprise I was able to split both A and D from C, the main star. As you see in the image, A and D are 12.9 arcsec and 13.3 arcsec apart from C, respectively. I guess the common chromatic aberration of binoculars and the reduced magnification make very difficult to split stars lower than 15 arcsecs apart. Are you guys able to split the trapezium
  4. Thanks for the reference. Definitely looks like Peter Drew is the man here to build binoscopes. I also know about Matsumoto in Japan. The alt-azimuth mount he uses is really smart, and would work perfectly with the two 6" refractor OTAs.
  5. Thanks for your comments Sapeceboy. That's why I'm considering F6 (the TS refractor), or the F5 iStar which according to reviews looks like something between a normal refractor and ED/Apo. Looks like lower chromatic aberration in these 2 scopes.
  6. Two refractors, one for each eye... My eyes are very selfish and don't want to share views with any binoviewer.
  7. Thanks Mike, could you send me pics and features of the two refractors on sale?
  8. Thanks guys for your input. Definitely the 10-12" dobson binoscope is on the cards, or maybe just one big dobson about 25" when my future observatory is ready. But now I just want to enjoy wide field views with a portable refractor binoscope with the maximum aperture possible. And that means a maximum of 6" or lower, to be portable. Forget binoviews with just one tube, I want two tubes, and focus the two tubes individually.
  9. I'm considering to build a nice all-round wide field 150mm binoscope, mainly to observe DSOs and, why not, some planet observations. The priority is wide field observation with good contrast at 5 pupil exit, and also good contrast on smaller DSOs at 2-3 exit pupil, so I guess the focal length should be 900mm at maximum. I don't mind too much some chromatic aberration observing the moon and planets at 100 X, I'm not aiming higher than 100-150 X for planets. I want this binoscope to be a keeper for life. I'm considering these refractors, and I would like to hear your suggestions and r
  10. Nice quick session. I managed another "hole in one" last Saturday aiming at NGC2451 in Puppis. Impresive its orange central star. With bins you can manage a lot of targets very quickly, some of them with a "hole in one".
  11. Good on you Andrew! Agree... better use apertures 70 or higher to enjoy the Christmas trees.
  12. 1st February 2016 (9:00/9:30pm CET) Clear night, semi rural skies in South Spain (my patio). Binocular TS Marine 15x85 with tripod. Nice view today with clear skies of NGC 2264,the large brilliant open cluster with the stellar pattern of a Christmas tree. Amazingly, this very young cluster (only 3 million years) was never included in the Messier list. Nearly all of of its 20 stars are visible in medium size binoculars. 15 Monocerotis is the brightest star of the cluster, and it marks the half-degree base long of the tree, pointing to the North. Through 15x85 binoculars the 8.2 mag ora
  13. I like the name you suggest: 'Binoculartistas' We are really artists ;-)
  14. With your new binos you can enjoy a field of view of at least 5 degrees. With a 48" dob only 1/4 degrees at maximum. So now you guess where you are severly limited...
  15. M79 is the biggest globular cluster in winter. Just below Orion in Lepus constellation.
