Description

Mit diesen Teilen könnt ihr den "astronomical-telescope-propdob-dobsonian-45-mirror-114900" von ScienceTechnology noch ein bisschen pimpen.

Ziel der Teile sind es, die Rockerbox um einiges stabiler zu machen.

  • Niederhalter für den Drehkranz - Verhindert das Kippeln unten herum.
  • Füße mit Loch - Da kann man einen langen Hering durchstecken, um die Rockerbox
    zusätzlich am Boden zu fixieren.
  • Halter für kurze Spanngurte (benötigt M4 Einschmelzgewinde und 4 M4 Schraubringe)
    Die Spanngurte halten die Höhenräder auf der Rockerbox und geben ein bisschen
    Widerstand, so dass sich der Tubus angenehm bewegen lässt und nicht sofort
    zurückwippt, wenn man das Okular wechselt.
  • Die Querstreben habe ich mit zusätzlichen Diagonallöchern versehen. Duch die
    zusätzlichen Diagonalstreben wird die Gitterkonstruktion "relativ" bombenfest. Es wackelt
    zwar immer noch ein bisschen, aber man wird beim Fokussieren nicht mehr seekrank.

Zudem habe ich den Rotary focuser von apruss verwendet, um einen Helical hinzuzufügen.

Meines Erachtens war der Leuchtpunktsucher nicht wirklich gut zu erreichen, daher habe ich den Halter umdesigned und auf die Ecke neben den OAZ positioniert.

Nun finde ich den kleinen Dobbi super und durchaus brauchbar.
Klar, der wird immer ein bisschen wackeln, aber mit den Pimps ist das echt unter Kontrolle.

With these parts you can pimp the "astronomical-telescope-propdob-dobsonian-45-mirror-114900" from ScienceTechnology a bit more.

The aim of the parts is to make the rocker box a bit more stable.

  • Hold-down for the turntable - Prevents tipping around at the bottom.
  • Feet with hole - You can put a long peg through them to fix the rocker box to the ground.
    • Holder for short tensioning straps (requires M4 thread and 4 M4 screw rings).
      The tension straps hold the elevator wheels (?) on the rocker box and provide a little
      a little resistance, so that the tube can be moved comfortably and does not immediately
      back when you change the eyepiece.
  • I have provided the cross struts with additional diagonal holes. Through the
    additional diagonal braces make the grid construction "relatively" bombproof. It still wobbles a bit, but you don't get seasick when focusing.

I also used the Rotary focuser from apruss to add a helical.

In my opinion, the illuminated dot finder was not really easy to reach, so I redesigned the holder and positioned it on the corner next to the OAZ.

Now I find the little dobbi super and quite usable.
Sure, it will always wobble a bit, but with the pimps it's really under control.
