Followings are the cropped close-up versions in full resolution mode.

All light frames were simply stacked. More experienced users should split into RGB individually and create AOO or Hubble Pallet or something else. I will learn that from now on.

I feel the image sharpness might be affected by seeing or the temperature change during the imaging session. Even my 75mm guide scope showed poor seeing.

I wish to use my lovely cooled 6D. But so far, there is no room for one more filter box at this moment. This is why I shot the above with A7. I need the special arrangement for that.

BORG with Eagle 3

I just setup PLL’s Eagle 3 with BORG 90FL F3.9ED and 50Ach guide scope. Fortunately I could figure out matching Eagle 3’s hole patterns with BORG 3200 plate.

ll look nice and great color matching, and everything is solid.

Again, Eagle 3 is not just a compact Windows PC. I think the power distribution capability including dew-heater power controls should be more valuable and convenient. I have to ship them out to NEAF today. So I will write up more after coming back.

Current BORG Availability & 72FL

I summarize current BORG availability for new orders as follows. (This is not for the ones already ordered)

(Objective lenses)

  • 107FL : May

  • 90FL : June

  • 89ED : June

  • 55FL : June or later? (I need more carefully check)

  • And 72FL : Prototype stage

(Rear lenses)

  • 7108/7215/7214/7872 : in stock

  • 7880 : May

  • 7770(=ED reducer for 107FL)/7771(=ED reducer for 90FL) in stock

Sorry for the inconvenience to you. Still way behind the schedule, especially 55FL. But getting slightly better. Thanks for your continuous patience.

I was told 72FL was refined for best matching with 0.72x super reducer. I will try to take some shots before NEAF if allowed or after. This is 72mm fluorite at F4 with total 6 elements configuration.

I will try to figure out best possible configuration as the double-duty scope for imaging as well as guiding.
