Feather Touching Takahashi FC100DL

[fedele]

Per preservare dal tempo e dall’usura lo storico focheggiatore nero del mio FC100DL, ho montato un focheggiatore Starlight Instruments 2" FTF 2025, con la flangia dedicata ( trovata disponibile solo in Francia) A20 -304 per Takahashi FS78 / FC100.
Preferisco il look con il classico focheggiatore, ma onestamente anche l'FTF è un bel vedere.

Pensando possa essere utile informazione per chi ha un FC100, ecco alcuni test di back focus che ho realizzato.

1) Visual @ direct Focus
Fok + GSO estention 50 mm + Taka estentions + Taka 2"/1 1/4" reducer + Taka Ortho 32 mm o TV Ploss 25 mm
2) Visual with Diagonal Baader T2 32
Fok + Taka Estention + T2 32 + Baader ultrashort ClickLock 2"/1 1/4" or normal Click Lock ok from circa 70 m to infinite with starting from Takahashi Abbe 32mm
3) ASI178 camera @ Direct Focus
Fok + GSO estention 50 mm + Taka estentions + Taka 2"/1 1/4"reducer (or Baader ultrashort ClickLock 2"/1 1/4")
or
Fok + GSO 80 mm estention +(or Baader ultrashort ClickLock 2"/1 1/4")
4) Baader Maxbright II
Fok + Baader T2 32 with 2" noise + Baader Maxbright II
finally works stably from the Takahashi Abbe Ortho 32 mm to the Takahashi TOE 4 mm
5) Baader Cool Ceramic 2"
No Sun, so not tested yet. Anyway i suppose that will work
6) Baader Cool Ceramic 2" + + Bino Baader Maxbright II
No Sun, so not tested yet.
7) Daystar Chromosphere with camera or visual (with and Without Bino)
Not tested Yet
