MASUYAMA 32mm & Astro Image

•October 24, 2016 • Leave a Comment

First, I’d like to thank all of customers who already purchased the eyepiece. All of 1st lot we received have been sold out quickly last week and we are now arranging 2nd shipment from Japan. We are expecting they should come in next week. Agena Astro should have the sufficient number of units in stock as well. So please contact them if someone are interested.

mop-32Thanks for the patience of the customer who are waiting for MASUYAMA 32mm.

Sam Berrada in Canada sent me his recent Ha monochrome image taken with 6DH. Looks very good contrast.

BTW, I went for HONDA’s fuel cell car presentation and drove their Clarity last week. They displayed Toyota Mirai and Clarity side by side. Honda wanted to clarify the difference of each concept. Yes, at the viewpoint of the overall quality as a car, I agree Clarity should cost more than Mirai’s.

Left is Mirai while right is Clarity. As usual, Toyota’s engine room is more simplified(?) or organized(?) cost-saved(?) while Honda’s is complicated. I always feel these might show each corporate engineering culture.

One good thing for me is there is Hydrogen refueling station just a mile away from my office.

Mirai’s 3-year lease offer is $350 a month and free refueling during the entire lease period. According to Honda, their lease should be similar to Toyora too. It’s bargain!! Probably the number of production is very limited for a while. I guess so many number of waiting list must be piled up quickly. In any case, it must take long time until they can start making the profit from these cars at this level of lease price.

If the fuel cell is categorized as motor-driven car along with EV, I think Honda Clarity should be compared with other luxurious EV. And 300+ driving range and quick refueling time, fuel cell seems to be more practical, at least looks so to me. For safety issue, Toyota is one of most conservative company in the world. I’m sure they have cleared all of aspects during the long-time crash test. Also the philosophy of Mr.Honda was the safety was the top-priority. So I’d like to trust Japanese engineering for safety and protection.




Rigel Motorized Focuser Option & Solar Movie

•October 21, 2016 • Leave a Comment

I noticed Rigel’s motorized focuser retrofit option seems to be more cost-effective solution. Some BORG users who are interested in PC control, please check their web site.


According to their web site, one of good features looks quick detach/attach function. I’m not sure how. But it looks convenient.

I used BORG 1.08x field flattener for solar imaging first time to “hopefully” improve off-axis image. Thanks for 2″ straight-type blocking filter.


A following is a pure single frame (without stacking multiple frames) with a field flattener. 1.08x ratio takes up to 650mm focal length. As shown below, this looks the longest focal length in 1/1.2″ sensor(13.4mm diagonal) for solar full disc.

A field flattener is in place.

MASUYAMA 32mm & Astro Image

MASUYAMA 32mm is now in stock.

mop-32Looking very nice. This was what binoscope users were eagerly waiting for.

BTW, I thought someone might be misunderstanding. MASUYAMA is a brand name as well as company’s owner name of an original manufacturer registered as “Ohi Optical Co., Ltd.”. MASUYAMA or Ohi Optical has long produced most of Japanese-made eyepieces under their brand name as well as so many different other names many people are still using.

Hutech’s one of very close partners in Europe  – Frist Light Optics in UK, James Mackay starts using BORG 55FL F3.6. Here is his recent shot.  Nice color and well composed.


BORG 55FL F3.6 + IDAS HEUIBII-EOS + Modified Canon 650D

James is fully knowledgeable on BORG system and First Light Optics is carrying wide variety of BORG parts in stock. Please contact James at FLO if someone in Europe are looking for BORG parts. You should get the good solution from him.

This is the trial shot with 600mm f.l. (89ED) and SF50. So it’s 50mm F12. The shutter speed was 1.xx millisecond. As DSLR measurement(I prefer), 1/700″ to 1/800″ I think it was not too bad. I wish the faster though.

Single 133 frames in 3 minutes interval.


 I will try to shoot with a field flattener next time to see any change.

We have IDAS QRO Series in stock now. LPS-D1 48mm/52mm and HEUIBII 48mm/52mm are currently available as top of the line in IDAS product lineup. LPS-V4 is expected to be coming up later.

1.1mm glass thickness minimizes the light path change. It has good advantage when it is set within the light path-sensitive optical train.

Also as shown below, CNC-machined precision frame is carefully considered for the reflections caused by the mechanical factors. The matte finish taper shape with clean knife-edge top mechanically avoids the internal reflections as much as possible.

qro2sIDAS continues to lead the astronomical filters optically as well as mechanically.

Deep-sky Shots & Solar Time-lapse Movie

•October 17, 2016 • Leave a Comment

One of Hutech cooled 6D camera users – Fritz Kleinhans shared his great pictures for deep-sky targets. Since this blog mainly shows wide-field image only, I thought these are something very fresh. Click to link to each his page.



I took series of solar image. Although my result is totally different level from recent Charles ones, I think this is somehow the best I can do as a lazy man at this moment. 66 single shots through SF50 and BORG 50FL F8 in 3-hour duration.

1017aI will try with a longer focal length optics next time. I hope the shutter speed will be still high enough. I’m still hesitating to make the efforts for stacking a number of shots to create one image frame. It requires the tremendous efforts I’m not totally pleased with. I wonder if someone will write up the program which allows for the batch process for multiple image holders throughout by one click.

Stunning Solar Activity Animation

One of HINODE solar guider users – Charles Shahar in Canada creates the gorgeous solar animations. See and enjoy his wonderful image. These look very good textbook for me to learn the solar activity. I think he is capturing through Daystar Quantum 0.4A filter. Really great image!!
