More about the product

Introducing the new EAF, the latest innovation from the engineers at ZWO. This electronic focuser enables precise, dynamic focus control for planetary and deep-sky imaging.

Compared to its old version, the main change of 5V EAF is to remove the 12V power supply port. Now you can directly connect it to your camera, laptop or ASIAIR PRO via the USB 2.0 port & cable for both data transmission and power supply. This would not only make the cable management much easier, also effectively reduce the supply pressure.

The innovative decorative pattern on the EAF is inspired by the changes of Airy disk during focusing and the focusing curve, which makes it clear at a glance how this focuser works.

Features:

  1. Highly integrated design
  2. Support ASCOM platform and various ASCOM-compatible third-party software
  3. Support INDI
  4. Support original software such as ASIAIR and ASICAP
  5. Support automatic focusing
  6. Support handle controller and manual focusing
  7. Support temperature sensor
  8. USB HID device and drive-free
  9. Stable and durable

Pros

Meade SC 10" OTA-hoz vettem. Tökéletesen illeszkedett a furatkiosztás a Meade-hez is. Azonban az OTA ANSI csavarjai rövidekenk bizonyultak. Nem találtam a piacon hosszabb csavart. Ezért lecsiszoltam az EAF-tartó alaplemezéből 2mm-t. Így fel tudtam használni a Meade csavarjait. Még jól is jött, mert a Meade fókusztengelyt centírozó perselyének is 2 mm a vastagsága. Az alaplemezt összeszerelve ezzel a centírozóval, visszakaptam a lecsiszolt méretet. A Meade fókuszírozója még ígényelt egy 5-6 mm vastag gyűrűt, amit a kuplung és a centírozó persely közé kellett legyártanom. Szépséghibája, hogy a kuplungot a fókuszírozó tengelyének menetes részén tudtam csak rögzíteni. Ezzel ugyan sérül a menet, de a célt elértem. Gyakorlatilag a Meade gyári kialakítása nem sérült. A fókusz megengedett tartománya nem változott. Az EAF megfelelően működik.

Cons

nincs

Summary

Ha EAF-ot akarunk használni egy Meade-hez, nyugodtan választhatjuk ezt a Celestron kiegészítőt.

Pros

Nagy mértékben megkönnyíti a fokuszálást és az egész fotózást. Az autofokusz is jól müködik, miután beállítottuk megfelelően a holtjàtékot. Jol parameterezheto az ASI AIR Plus-ban, példàul megadhato, mikor végezzen auto fokuszálást (idö, hőmérséklet változás, szűrö csere...).

Cons

-

Summary

ASI AIR Plus-al használom 25 centis Newton tàvcsövel, 2 sebességet fokuszirozoval. Segítségével teljesen tavvezerelhetöve vàllt a tàvcsövem, igy sokkal kényelmesebb a fotózás.
