New Triplet Reducer

0.85x reducer (#7887) worked very well with Borg scopes.  Also I had a lot of excellent feedback from non-Borg scope users. There are currently many users who are taking astrophotography with it. Although it’s been well known as optics which makes images flatter and sharper, it’s been discontinued.

Now we plan to release newly-designed triplet reducer for 500mm to 1000mm focal length. It’s faster – 0.78x,  flatter illumination entire 35mm full format  – 88% with 101ED and sharper. As usual, it should work well with any other doublet/triplet refractors as well.  This creates much less light drop-off and image distortion at the corner. So I believe this should be very helpful for 35mm full frame mosaic.

This is the prototype. I will keep you updated on test image with this new reducer.

 

 

Little Planetary Scope

Borg 50ED II (F10) should be the ideal resolving power as 2″ aperture. It works very well visually too. Surprisingly we can see the details of the Jupiter with this little scope well. Probably very high contrast capability must be the key factor for that.

Kinｇfisher

Kingfisher is called several names in Japan. One is written the meaning of the characters – “Jade” since it looks greenish in a certain light angle. Following is the one example.

The details of feather are well resolved.

Here is its most favorite time.

These are all taken by 77ED II + 1.4x teleconverter +Olympus E-3. This system might be overall highest score in portability(handheld), focal length(1400mm equivalent to 35mm full format) and camera’s image stabilizer. The focus was done through the focus indicator adapter.

Iris M57

Borg releases 1st iris unit, which allows to adjust ID 5mm to 47mm. Amazingly it has 20 blades – virtually round iris shape. Since both ends have M57, it can be used with any of Borg scopes. But larger objective apertures requires setting it further from the objective. As the result, the control of the depth of the field is less effective. So it is the best match with Mini Borg series. It can be set in front of camera lenses too.

Nipponia nippon

Toki(Nipponia nippon) in Japanese is specified as one of natural monuments and the endangered species in Japan. Now they are bred at only a few places in Asia. One is the island of Sado, located at the west of Niigeta in Japan Sea. Here is the one of them called “Kazumi”. Each has a unique human name.

Lightweight Borg

One of advantages for Borg scopes is lightweight.  Especially it should be  extremely big benefit for carrying to the mountains. Here are some examples.

Wide-field Astro Imaging by Canon 5D Mark II

5D Mark II is well recognized as astro camera in excellent noise and sensitivity level although the number of pixels is increased from previous model 5D’s. As a result, users’ rating as astro camera is getting higher and higher these days. Here is one example taken by Alan Dyer.

The camera captures a lot of very faint nebulosity sections. All are beautiful!! So 5D Mark II works very well for wide-field astro imaging.

Panasonic GF-1

This is really good camera for DigiBorging. Good match with high-resolution optics. Looks like one of best DSLRs  I have ever used. These are easily focused with an external EVF. I will keep you updated on this camera.
