  1. APM 150 mm 45 ° ED-Apo Bino for 2 Inch Eyepieces High End ED-APO-Bino! APM binoculars are among the most powerful binoculars in the world. The lenses with an extremely large diameter of 150 mm and the high-resolution optics with state-of-the-art broadband multicoating guarantee extremely bright and sharp images, on which every detail can be seen from a great distance. The high-quality Extra Low Dispersion ED Glass FK-61 reduces the possible residual color errors to a minimum. The extremely precise adjustment also allows high magnification factors and is characterized by an excellent resolution. These binoculars are of course waterproof and weatherproof and therefore suitable for outdoor use. With a 150 mm binocular we can already observe extensive gas-fog objects and galaxies with great details. Larger star clusters are resolved into single stars. Through the use of binoculars faint celestial objects appear much brighter and more contrast than with a conventional telescope same opening. Particularly attractive are observations with screwed-in fog filters on objects such as e.g. the Orion Nebula, Cirrus Nebula, or the Dumbbell Nebula. You can also create a virtual 3D effect, e.g. recognize in lunar observations. The intended use of APM’s 150mm binoculars is for low to medium power Deep Sky Observing, as opposed to planetary observation. APM’s 150mm Binoculars has the added advantage of allowing and doing well with planetary observation, showing details that are otherwise normally seen with large aperture instruments accompanied by Binoviewers (such as TV Binoviewers) while still having a smaller aperture and the advantages that come with it (including being less sensitive to adverse seeing conditions). APM guarantees good image results up to 100x power with its 150mm binoculars. Current users have gone beyond this point and are found to be happy with the higher power performance; however, higher power performance is not guaranteed by APM. Integrated are sliding dewlaps with front end cap, a hand-grip handle with a sighting device, a photo tripod adapter with 3/8 "threaded connection and 2 x 30-mm eyepieces 74 degrees with 28x magnification. To keep the glass light, the case was built from a magnesium alloy. Applications for the APM 150 mm 45 ° ED-Apo Binoculars: Astronomy - the 45 ° -view allows a pleasant viewing behavior (for medium heights, for Zenith observations a corresponding tripod is needed) Viewing and surveillance binoculars - even for distant objects (such as targets, navy, military, police surveillance, whale watching ...) Bird watching, wildlife observation, nature observation - also very comfortable view at medium altitude above the horizon New: now waterproof and with nitrogen filling Delivery contents: 150 mm ED apo binoculars with handle and tripod adapter 4 Dust Caps Set 30mm UF 74 degrees eyepieces = 28 x magnification Collimation Protocol for 100 x magnification Strong plastic transport case with foam fitting The APM 150mm ED APO Binocular is one of the most powerful binoculars in the world. Including 2" Eyepieceset UF30mm an Case Apparemment les PO sont en 2"
  2. Merci. Je crois avoir lu que c'était des doublets.
  3. Ah bon, qu'est ce qui fait la différence en bino vs mono au niveau du champ des oculaires ?
  4. C'est un peu limite en champs 60°
  5. C'est des flatfield de quelle marque ?
  6. Je ne les ai pas encore. En fait, je vends tout mon matos astro, et comme j'ai 4 Nagler en 1.25", 12, 7, 5, et 3.5, je me demandais si c'était adapté aux jumelles, dans ce cas je ne les vendrais pas, et je rachèterai les mêmes. Mais je préférerais quand même tout vendre et racheter d'autres oculaires en doubles, adaptés mais moins chers.
  7. Bonjour, tout est dans le titre. Merci pour vos lumières.
  8. Caméra, choix, CCD, CMOS, que choisir

    Sinon y a ça aussi
  9. Pour les focales conséquentes ça c'est le top. Non ?
  10. Vraiment de la merde ces cmos, ccd never die 😂
  11. Ts 125 ou Altaïr 125 ?

    Ce post me rappelle un peux ceux d'une célèbre grenouille, ou au bout de 248 pages, toujours rien ne répondait aux attentes de l'auteur. C'est bien de réfléchir un peu, et de prendre conseil avant de ce décider, mais il faut aussi s'apercevoir quand on recherche le mouton à 5 pattes.
  12. Un truc pas mal aussi, c'est de la sous face de parquet flottant épaisse de 4mm avec une face aluminée. Très léger, souple, et solide.
  13. Je crois pas dire une bêtise, il me semble que sur les mak bien fait, le diamètre réel est celui du ménisque, le miroir étant plus grand.
  14. C8 - Edge et train optique en visuel

    Bonjour, la barlow fait ressortir le foyer, s'il y a suffisamment de back focus sans elle, aucun problème avec.
  15. C'est la déflation, j'avais les mêmes diamètre d'axe pour ma petite trassud, et elle était donnée pour 50 kg de charge.
