[重要] 关于高桥TOA130和AP130的比较。

希望大家一起讨论下。

下图是AP130。
130mm f6 StarFire EDFS 5.1" Aperture (130EDFS)

At last, an easy-to-use amateur telescope that can produce exquisite astrophotos with almost no effort and show excellent planetary images as well. Versatility is the hall-mark of our refractors whether you wish to study the brush-stroke detail of sun spots or lunar crater detail; or enjoy wide-field deep-sky objects and CCD imaging with the fabulous cameras on the market today. Fast, high-transmission optics provide breathtaking wide-field views of your favorite deep-sky objects. Rich-field viewing at its best. Attach your favorite 35mm camera or Pentax 6x7 with our optional 2.7" field flatter for photos worthy of publication. With our telecompressor, you can photograph at a very fast f4.5! Or, attach our Convertible Barlow and enjoy views or photography with an f12 focal length. Enjoy the images taken with this scope as featured in our gallery. It was once described by a noted astronomy writer as a "Traveler on steroids"

This scope has 53 % more light grasp than a Traveler, yet it is still friendly and inviting to set up. The compact size and light weight ensure easy portability. It will pack easily into your car, even with your kids or other gear. Set up is a breeze whether in your backyard or favorite dark-sky site. You will use this scope often.

Please refer to these sections for additional information: Optical Design, Optical Production and Testing Standards, Construction of the Tube Assembly, Astro-Physics 2.7" Focuser.

The 130 f6 StarFire is at home on either our 400GTO or 600EGTO German Equatorial Mounts. If astrophotography is your primary love, pair it with our 600EGTO and 42" pier.

The TOA-130 by Takahashi©

ARRIVING NOW AT A DEALER NEAR YOU!


The newest Takahashi refractor, the triplet TOA-130, is the first of the new Ortho-Apochromat Series.

This 21st century innovation employs a newly designed triplet using special elements to produce the highest order of color correction, hence the name Ortho-Apochromat and is packaged in a short 32” tube with the lens shade retracted.

This instrument will be offered with the classic 2.7” focuser. For those wanting to use a medium format camera, we will offer a deluxe 4” focuser with built –in camera angle adjuster. This focuser, coupled with the dedicated flattener, will produce a fully illuminated 70mm circle with a usable 92mm diameter.

The high order of color correction of the Ortho-Apochromat Series produces images with saturated color and thanks to the numerous knife-edged baffles, an image with amazing contrast.

The TOA-130 is perfect for visual, CCD and photo imaging. The f/7.7 focal ratio with a 1000mm focal length is long enough, using the LE-ED 2.8mm Takahashi ocular, for high magnification observations of the Moon and planets and yet will produce a 2.5° field at 20x when used with the Takahashi flat field LE-50 2 “ ocular.

Ample back focus, over 200mm from the rear cell, has been designed in to permit the user to use a variety of CCD cameras, color filter wheels and electronic focusers or film cameras.

Price: $11,995.00

记得国外有评测说不相伯仲.但AP130等候时间太长,所以选TOA130没错.

但排除这个因素，大家谈谈一些细节特别是功能上和在接各种相机CCD上的优势吧。

TOA130可以了，但配件要全一些，比如平场镜/缩焦镜、行星观测目镜、星云观测目镜、增倍镜等。

解兄要购大洋炮啊！

这个很贵的

为什么不考虑TEC 140/7 APO呢？比这两个都便宜，而且做工也超一流。

TEC 140/7 APO价格是多少呢？好买到吗？

[B]TEC 140/7 APO价格是多少呢？好买到吗？

赫赫，好象也不怎么便宜啊。

4800USD，应该只是OTA的价格，不过还是比那两个要便宜些，但它是好象没用莹石。

TOA也没有莹石啊，TEC 140的光学部分是腾龙加工的，用的是SD玻璃，3片结构，BBAR镀膜，机械做工一流，到底还大10毫米呢。

我觉得还是这个比较合算：
TMB 152/1200 triplet Lens in cell  HK$28,200
然后花点小钱买个国产的152/1200，把物镜给换掉... ...
