BORG 90FL

banner_90FLEach price has been set as follows;

DSC01530s2590 – 90FL objective assembly (white) : $1,695.00

2591 – 90FL objective assembly (black) : $1,765.00

950g / 145mm long

Current Series 80 users can simply swap the objective assembly if a short tube is used. Standard 205mm long tube (#7800) is definitely too long in any cases. 150mm long is perfect with standard Feather Touch 2″. BORG helical focuser (7835) and FTF-M57 requires further shorter one such as 135mm(7135) or 100mm (7102) depending on each user’s system requirement.

DSC01787s6290 – 90FL OTA (white) : $1,895.00

2.0kg / 443mm long

DSC01775s6291 – 90FL OTA (black) : $1,965.00

2.0kg / 443mm long

At this moment, there is no optically optimized reducer 90FL. But in my test, 7887(0.85x) works with up to APS-C sized sensor. 7108 – 1.08x field flattener is good for full frame sensor too.

DSC01580s6190 – 90FL Telephoto lens set : $2,480.00

2.3kg / 420mm long

As mentioned early, 1st 50 units comes with a fluorite crystal and pouch.

  1. Hey Ted,

    Those are nice-looking units. Two questions:

    1. What is the weight of #2590, the 90FL objective assembly?

    2. I have the Borg 100ED with the 2″ Feather Touch focuser. Is the 90FL directly interchangeable with the 100ED objective assembly?

    Thanks!

  2. Hey Ted,

    Never mind about the weight. Found the 950 g. in your post.
