INTES MICRO 的6寸马卡镜。
这款是INTES MICRO 6寸马卡镜,焦比是F15。是一款物有所值的镜子,不用我多说了吧。。。。。。
它的特色和参数资料.还有玉照等,我都把它们弄在一张图了。
大家就自个看好了。
镜子后面还有MADE IN RUSSIA 的字样(俄罗斯造)。。。俄罗斯正宗马卡镜。
^^ Intes-micro的马卡虽然不错,但是绝对称不上APO杀手。
只有口径大上两寸的intes-micro 马卡才能和高级4寸APO镜子在反差,锐利程度上一比,总的来说intes-micro的像比较soft. 敬佩天星班主孜孜不倦地收集资料!
俺看过一篇讨论反差的文章,关于APO镜和折返镜的对比,从反差和锐度上来看,最简单直观的经验公式是:口径D, 中央遮挡d的理想折返镜和口径(D-d)的APO镜相当。 敬佩天星班主孜孜不倦地收集资料!

差不多,不过按照这个算法,似乎6寸的intes-micro能和115毫米的APO相当,但是实际只要是对比过两者的,一般都会毫不犹豫选择后者。
我个人感觉,只有FS 102,TV 102这种镜子和6寸的intes-micro马卡的选择才会让人难以选择,不过后者的价格似乎也和4寸APO差不多了。 拿焦比10的Intes Micro Alter603 六寸马卡镜为例, 中央挡光36%, 根据D-d的经验公式, 它的锐度和反差与3.84寸的APO镜相当(分辨力会好些, 但未必能赢4.5寸的TMB), 难怪目视感觉与FS102或TV102等四寸镜不相上下. 不过其1300欧元(不含运费和税)的价位也离4寸APO镜不远了. 好像intes-micro的镜子口径越大,中央遮蔽率就越小。
玩intes-micro的马卡,至少要买到7寸,不过7寸的价格也比4寸APO贵多了。 这个6寸马卡怎么着也比4寸apo强吧?反差锐度没办反,分辨率会输给5寸apo么?有经验的同好谈谈吧 Intes-micro的马卡虽然不错,但是绝对称不上APO杀手。

是的,无可否认APO折射镜会比马卡镜来得锐利。 ^^
“APO杀手”是人家给的,并不代表马卡镜全面都胜过折射镜啊。。
你也可以说反射镜是APO的杀手,为什么呢?
反射镜没有色差---胜----APO镜稍有色差。
反射镜很便宜-----胜----APO镜不便宜。
所以说这是人家给的称号,不需放在心上。。
不过嘛,只是比反差,锐利是单方面的。我们应该比全面的吧。。
不如我们拿高桥的FS102(算是高级APO吗?)比INTES MIRCO6寸马卡镜,你认为如何?
1)价钱
2)色差
3)重量
4)反差
5)锐利
6)分辨率
7)像差
8)体积
9)视场
10)其他误差
11)其他等等
这样一来,大家都知道各别的优点和短处了。。不会笼统的说来说去的。
小蔡兄意下如何?

也对。4寸APO望远镜,各厂商出的价钱到底是多少呢?
我也想比较一下。最便宜和4寸APO到最贵的4寸APO,它们会差多远? ^^ 不如我们拿高桥的FS102(算是高级APO吗?)比INTES MIRCO6寸马卡镜,你认为如何?
1)价钱
我这里前者21万,后者也21万日元。
2)色差
intes-mirco要稍微好点,但考虑到反差,这种优势根本不能算优势。
3)重量
都是5公斤上下。
4)反差
FS102远胜。
5)锐利
同上
6)分辨率
由于以上两种原因, intes-micro并没有优势。
7)像差
眼视看都差不多。
体积
前者细,后者短。
9)视场
都不大
10)其他误差
当然是FS 102不容易产生误差。
11)其他等等
其他后者也缺乏对前者致命的优势。
最后看看2手价值,2手的Fs 102至少能6折扣出手,2手的intes-mirco马卡半价都卖不到。 6寸马卡比不了4寸apo?至少看深空好得多吧,行星分辨率上还是能够看出来吧。记得国外有文章讲c5拼不过tv102,是经过仔细比较得出的结论。还是请有经验的同好谈谈 拿焦比10的Intes Micro Alter603 六寸马卡镜为例, 中央挡光36%, 根据D-d的经验公式, 它的锐度和反差与3.84寸的APO镜相当(分辨力会好些, 但未必能赢4.5寸的TMB), 难怪目视感觉与FS102或TV102等四寸镜不相上下. 不过其1300欧元(不含运费和税)的价位也离4寸APO镜不远了.

这里有一只目前售价最便宜的准APO 4寸ED镜, 只售800美元, http://tinyurl.com/5h6fw
看介绍吹得很厉害:
"One of the more frequent questions we get here at Astronomics is, “What sort of telescope do you have that has a wide field, good optics, and is airline portable?” Our answer is limited mainly to refractors, all of which cost between $1500-$4000 with a diagonal. Well, Burgess Optical has changed that answer forever with their SD 101 Backpacker. With a tube length of only 16.5”, which includes the 2” dielectric star diagonal, and an ED f/5.5 doublet optical system the SD 101 Backpacker dares you to find a better performing portable telescope even at twice the price.
The SD 101 Backpacker could be the answer to all of your portable telescope problems. The name should tell you all you need to know about its portability as it comes in a Backpack style soft case with cutout foam for substantial protection against everyday bumps and bruises. The tube comes in at 13.5” long, with the dew shield retracted, and 16.5” long with the supplied 2” dielectric diagonal attached, so airline regulations for carry-on luggage should not be a problem for this particular instrument.
The tube itself is a mechanical marvel from front to back. The fully CNC machined light grey tube will rival any high end refractor with its sliding dewshield and 2” rotatable Crayford focuser. The tube is designed and built by William Optics with their legendary fit and finish. It’s precise mechanical engineering is evident as soon as you pick up the tube.
The great mechanics and finish are nice to talk about, but what about the heart of the telescope? The optical system of the SD 101 Backpacker is no slouch. Its ED f/5.5 doublet objective has been rated by the manufacture to have 8x the color correction of an achromatic lens of similar aperture. While it isn’t quite apochromatic performance, it is far superior to anything else in its class. A refractor of this particular speed should be good for roughly 45x per inch of aperture. Lunar and planetary viewing will be fine, but star clusters, galaxies, and nebulae are really where the rich field should shine.
The Burgess slogan is, “To Make Awesome Affordable” and the included accessories with the SD 101 Backpacker prove that without a doubt. Most manufacturers stop at the optical tube and then have all the other accessories ala carte, not so with the Backpacker. The package includes the SD 101 Backpacker optical tube assembly, the backpack carrying case, CNC machined tube rings (so you can mount the scope on your favorite mount), a 2” dielectric star diagonal with compression rings as well as an 1.25” eyepiece adapter, and a 38mm 2” wide field eyepiece.
If you are a person looking to add another scope to your arsenal, an observer looking for the perfect balance between aperture and size, or and adventurer traveling to the four corners of the earth eclipse hunting the SD 101 Backpacker should fulfill all your wishes and more."
真是林子大了什么鸟都有 6寸马卡比不了4寸apo?至少看深空好得多吧,行星分辨率上还是能够看出来吧。记得国外有文章讲c5拼不过tv102,是经过仔细比较得出的结论。还是请有经验的同好谈谈
不奇怪。看过好几篇文章关于4寸顶级apo和8寸施卡(LX90或C8)的比较,主要是行星和月球方面。在seeing很好的时候,8寸施卡明显占优,一般seeing的时候,8寸的口径优势显示不出来,反而apo的成像看起来更舒服点。总地来说,差不多吧。因为毕竟seeing好的时候少啊。
4寸apo能跟8寸施卡打个平手,超过6寸马卡没什么可惊讶的。
深空方面的比较少,我觉得4寸apo和8寸施卡,看双星团这类面积大的,肯定是4寸apo好,视野大。话说回来,如果论到视野,除了61式对空镜,那个能比我的80400强,最大6度视野呢。但是毕竟口径差距太大,对于很多很多天体,8寸施卡和4寸apo的区别是看得到和看不到的问题,更不用去比什么细不细节了。看深空还是得用大口径啊,对于有些比较大的深空天体,带个短焦普通80折射作为个补充就是的。
考虑价钱的话,4寸顶级apo可比8寸施卡贵多了。
所以说还是8寸施卡比较好。跑题了,跑题了,呵呵。 6寸马卡比不了4寸apo?至少看深空好得多吧,行星分辨率上还是能够看出来吧。记得国外有文章讲c5拼不过tv102,是经过仔细比较得出的结论。还是请有经验的同好谈谈

精细的观测需要视宁度,大口径的镜子观测行星会找一个seeing好的时候,环境是一个问题。我是想知道在比较好的情况6寸马卡和4寸apo究竟有什么差别?优势劣势都在哪里? 我个人是比较倾心intes-micro alter-7P的,虽然这个镜子的价格赶上NP 101了,但是效果不是NP 101能比的,从行星观察的角度看,它的分辨率具有这个口径的数值,反差等可以和口径130+APO媲美,考虑到行星基本都属于高反差的天体,买7P来代替130毫米以上的APO来高倍观测,不论从银子还是体积重量上看都很合算。 不如我们拿高桥的FS102(算是高级APO吗?)比INTES MIRCO6寸马卡镜,你认为如何?

的确,二手的INTES-MIRCO马卡在市面上价值不高。。
所以我在6寸马卡镜方面,会选INTES 69 MAK 摄星镜或6寸的马牛镜看深空。而不看高反差天体。
