BORG with Eagle 3

0329a.jpg

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.

A breathtaking eclipse

e were blown away by this stunning image, beautifully illuminating solar activity behind the moon. It was kindly supplied to us by Prof. Dr.-Ing. Adalbert Ding of the Institut für Technische Physik (ITP), and the Institut für Optik und Atomare Physik, Berlin.
Here’s what Adi said about this capture:-

The image is composed of 3 separate pictures:-
• The electron density (blueish, so called white light picture)
• The emission of Fe XIV (530.3nm: Fe 13+; green areas), depicting areas with temperatures around 1.8 MK
• The – NIR – emission of FeXI (789.2 nm: Fe 10+; red areas approx. 1 MK)

The reddish parts top and bottom of the moon are the magnetic north and south pole of the Sun, the field lines moving nearly linearly away from the Sun in these regions while the magnetic field lines connected to the Fe XIV seem to be mostly closed loops. The start of the solar wind can be easily seen moving away in different directions.

The image of Fe XIV had been taken with the ATIK 314, the image of  Fe XI with ATIK 414, both in connection with narrow band filters, the white light pictures with a CANON Mark III full frame.

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.
