Fokussierer

Being mainly involved in deep sky imaging with automatic focus control, I somewhat lost the feeling for visual observing objects of our solar system. Therefore, I purchased a highly portable Alt/Az mount for my visual gear. All refractors are equipped with Feather Touch focusers and make use of Optec’s FocusBoss II, which can drive all my focus motors. Despite of the fact that focusing by hand is easy with the above-mentioned focusers, a relaxed sitting position during planet observation - imho essential for satisfying observation results - and focusing in parallel is sometimes cumbersome. Consequently, I decided to purchase the FocusLynx Hand Control which is a perfect fit to my FocusBoss hub and is a relief for acrobatic focuser handling during observing. After ordering the hand control at Baader Planetarium, it arrived already next day. I was expecting a plastic gimmick and was really surprised: The aluminium housing feels extremely premium, the finish is perfect. I immediately connected the hand control to the hub with different focus motors attached – all motors worked perfectly after setting the correct values in the hub software (the software offers the most common motor types). With a computer attached to the hub, I computer-synched the motors at different positions, which was immediately reflected in the hand control display (this hold also true for and vice-versa synching). De-connecting and re-connecting the hand control works without any flaw, parallel use (hub attached to hand control and computer in parallel) is void of any issues. Focusing can be achieved using the turning knob or the “in” and “out” push buttons – I personally preferred the old-fashioned push buttons (the buttons behave in an accelerating manner when holding them down). By pressing the turning knob down, focusing speed is toggled between 1x -> 10x -> 100x speed (1x = single step resolution, 10x = ten step movement with each encoder tic, and 100x for high speed and longer travel moves), a nice feature! The top left button is the “mode” button, used to cycle between the “firmware information screen”, “focuser 1”, “focuser 2” and the “home/sync” focuser screens. The focuser screen will display the focuser nickname (to be set in the hub software), the current position in steps and temperature (if a temperature probe is attached). Using my Optec QuickSync focus motor with an internal temperature probe confirmed the expected display read-out. And here comes the major downside of the hand control – obviously the hand control display was designed for nighttime use – during daytime (solar observing), the display is NOT readable. It would be great if Optec could add a dimming function to this hand control, then it would be perfect for me. The hand control comes with two standard coiled telephone handset cables (long and short) which attach to the RJ22 socket on the bottom of the hand controller – a nice feature for everybody who prefers to tailor-crimp his/her own cables. In summary, I am very delighted with this hand control and can really recommend its purchase and use.

Schnelle Abwicklung und Lieferung, Fokussierer funktioniert einwandfrei. Gute Verarbeitung und Anleitung zum EInbau.

Der Handcontroller ist robust und schwer in Metall ausgeführt, das Display ist rot hinterleuchtet und blendet nicht - so soll es sein!

Der Focus Motor konnte einfach und mit dem beiliegenden Werkzeug problemlos installiert werden.

Ich habe den Feathertouch sehr schnell einbauen können. Die online Beschreibung waren dabei sehr hilfreich. Also: echt einfach. Das Ergebnis ist ein extrem genaues Justieren der Fokusposition. Ich benutze dazu an einem Stern ein Justage-Maske. Ich kann durch den Feathertouch Micro Focuser für Celestron HD11" / CPC1100 / C11 immer reproduzierbar den Fokus einstellen. Am Messier Objekt M101 (11"EdgeHD, Nikon Z6, ISO4000, 240 s, 10 Bilder) und den Kometen C/2019Y4 (am 22.04.2020, 11"EdgeHD, Nikon Z6, ISO 8000 90s, 1 Bilder) kann man dies schön sehen. Absolut lohnenswertes Zubehör!

Ich habe den Fokusmotor an meinem 8se auf CGEM DX Montierung angebracht. Die Montage und Kalibrierung verliefen Dank der gut verständlichen Anleitung problemlos. Ich steuere die Montierung und den Fokuser über die CPWI Software aber auch über die direkte PC Steuerung mit dem Fokuser-Programm läßt sich der Motor sehr gut ansteuern. Ein tolles Produkt das ich sehr empfehlen kann.

Habe meinen Standart Focuser an meinen Teleskop duch den Feather Touch Micro Focuser ersetzt. Kein Vergleich. Fokusieren kann so einfach sein. Hervorragendes Produkt. Sehr gute Verarbeitung. Bin sehr zufrieden damit. Schnelle Lieferung. Sehr gute Verpackung. Keine Beanstandung.

A very nice addition, sturdy and nicely crafted, for my edgeHD 8" SCT astrophotography setup. Very nice build and performs great out-of-the-box. Also with the intention to create a fully automated focuser setup. Its good to know that with the edgeHD 8" SCT setup, you will need to use the original orange adapter plate as well so you keep the full focus range. This is the only additional step needed for a edgeHD 8 and not being documented. The installation is indeed as simple as mentioned in the documentation and was done within 15 minutes.
