たどり着かない、Video Astronomyの体験談...
Rod Mollise: Observing with Astro Video Cameras
オリジナル記事はこちらみたい

Below are some citations taken from Rod Mollise's
article Observing with Astro Video Cameras that he wrote
for Sky & Telescope! Please note that he discusses
the original concept of video astronomy without
using a computer for image stacking.
この方のはスタッキングは使ってないのを割り引いて
考える必要があると。


Some Newtonian reflectors don’t have enough focus
travel to allow the use of a camera of any kind when
the camera is inserted directly into the telescope's focuser.
Refractors will usually work without any modifications.
Telescopes that move their primary mirrors to focus,
like Schmidt-Cassegrains and Maksutov-Cassegrains,
rarely have focus problems with cameras thanks
to their wide focus range.
う~んどうやら天体望遠鏡の方式によってピント合わせの
有利不利があるようだが..まあそこはいいや。

光害に関しては、最初に、
It was even more appealing that they were doing
it from light-polluted suburban sites
いやだから、それがどう実現できてるかなんだが

It was even more appealing that they were doing it
from light-polluted suburban sites! My buddies
were using special cameras from Mallincam (mallincam.com),
Cosmo-Logic Systems (formerly StellaCam,
cosmologicsystems.com), and Orion Telescopes
& Binoculars (oriontelescopes.com).
These cameras had several things in common
that allowed them to capture deep-sky objects.
該当部分は上記の様だが、カメラが特殊だとしか書いてない。

ここでカメラを漁りに行くのは止めておいて、次のレビュー

ただ読むとほとんど望遠鏡の倍率とセンサーの関係の話
ばっかだな~

Gerd WaloszekさんがeVScopeの前に試したやつですね。
これは後回し

Preliminary Conclusions
In my opinion, there is no "good" or "bad",
no "right" or "wrong" in this regard.
まあ、そうだよね、その人にあった方式を使えばよいので
いい・悪いの問題ではない。
...全面的に賛成。

I can fully understand that die-hard visual
observers, who may even create drawings
from their observations, pick on this direction,
especially when people are "watching" from
the couch using their laptop or smartphone,
and drink beer and munch potato chips-
and the telescope stands forlorn outside
on the cold terrace.
Likewise, I can understand when "real"
astrophotographers pick on direction,
because they have to invest a lot more
time and effort in their results and have
to wait longer until they see any results.
カウチポテト(ふ、古い)で楽しみたい人もいれば
それに背を向けて寒空に望遠鏡を担ぐ人もいると。
※一応カウチポテトのwikiをリンクしたが、
まあこのblog訪問者は、あ~そういうのあったねっと
通じるはずだが、知らない(つまり若い(爆))読者いないよね?
例によって、漫画だが、めしばな刑事で、若手の警官に
通じないというのがあったんだが、念のため...

So, for whom is the new direction? I mentioned already
the "couch astronomers." Then there are the
impatient ones, those who do not want to spend
a lot of time with star gazing, and the "ignorant"
ones who hardly know or do not know the stars
and the constellations in the sky,
but still want to see "something".

静岡県は三島より、自転車の記録及び書籍や音楽・映画等の記録を、お送りします。
先達のコース記録で色々勉強させてもらっているので、私もなるべくコースの感覚などを伝えられればと思います。
