惑星用のCMOSカメラの調子が悪い(-_-)
販売店で調べてもらったかぎりでは「異常なし」とのこと。
でも私の2台のPCでは認識したりしなかったり、接続出来ても直ぐに切断されてしまう。
大赤斑が見える絶好の機会だったのですが、、、う〜んストレス(-_-)
木星で色々格闘していたので、月も西に傾いてしまった。
望遠鏡で覗いてみると、ゆらゆら揺れている、、、
あっ、そういえばIRパスフィルターがあったなぁ。
と言うことで使ってみました。
多少は効果があったかも。

La Nebulosa Variabile di Hubble, catalogata anche come NGC 2261, è una piccola nebulosa nella costellazione boreale dell'Unicorno (Monoceros), fisicamente localizzata a 2500 anni luce dalla Terra.
La nebulosa è visibile grazie alla luce della stella R Monocerotis, posta sull'estremità destra della nebulosa (la si scorge anche in questa fotografia).
Il nome di questa nebulosa deriva probabilmente dal fatto che è stato il primo oggetto fotografato con il telescopio di Monte Palomar il 26 Gennaio 1949 dall'astronomo Edwin Hubble.
Perchè "variabile"? Perchè andando a confrontare sue immagini prese a distanza di anni o a volte anche mesi si riescono a percepire piccole variazioni nella sua forma e luminosità: si pensa che il motivo sia legato alla presenza di dense nubi di polveri che periodicamente bloccano la luce della stella R Monocerotis.
----------
NGC 2261 (also known as Hubble's Variable Nebula) is a small nebula located in the constellation Monoceros.
The nebula is illuminated by the star R Monocerotis (R Mon), which is visible at one end of the nebula.
NGC 2261 was imaged as Palomar Observatory's Hale Telescope's first light by Edwin Hubble on January 26, 1949, so I suppose this is the reason why it was named so.
From physical point of view, it is located at 2500 light years and it is known for its (small) changes in shape and brightness, visible also with small telescopes over months or also weeks.
One explanation proposed for the variability is that dense clouds of dust near R Mon periodically block the illumination from the star.

今年は梅雨明けが驚くほど早く、ベランダでの惑星撮影も早々に再開です。
明け方には多くの惑星が見えるのですが、ベランダからだとこの3惑星。
この日はシーイングが良く、木星の細かな模様やガニメデ、土星のカッシーニの間隙もディスプレイで見えていました。
火星は撮ってみたら案外と写っていましたが小さいですね。

NGC 7814 è una galassia a spirale nella costellazione di Pegaso, alla distanza di 53 milioni di anni luce.
E' caratterizzata da una banda scura di polveri che la attraversa nel piano del disco: e questo è il tratto distintivo di questa galassia, anche perchè dato l'angolo di inclinazione con cui si mostra a noi, non è possibile avere ulteriori indizi su quale sia la sua struttura a spirale.
Il colore giallo diffuso attorno al nucleo è forse indizio di un basso processo di formazione stellare.
Da notare sulla sinistra di NGC 7814 due galassie molto deboli: potrebbero essere in effetti due galassie compagne.
----------
NGC 7814 is a spiral galaxy located in Pegasus constellation. Its distance from the Milky Way is 53 million light years and the angular size of 5.5’ x 2.3’ corresponds to a real diameter of 85000 light years.
The galaxy is seen almost edge-on and is featured by a dust lane in the plane of the disc: the high angle of inclination prevents one from saying anything about the spiral pattern of NGC 7814.
The diffuse yellow light from the bulge lends weight to the hypothesis that the current star formation rate of this galaxy is low.
Several other galaxies are visible in the image: to be noted two very faint galaxies on the left side of NGC 7814 which could be its satellite galaxies.

L'immagine mostra al centro una grande associazione di stelle immersa nella parte meridionale del disco della Grande Galassia di Andromeda, a 2.5 milioni di anni luce di distanza.
L'associazione è catalogata come NGC 206 ed è composta da stelle blu di classe spettrale OB, quindi molto giovani (meno di 10 milioni di anni di vita) e con elevata temperatura. Su un lato di NGC 206 sono visibili anche delle macchie rossastre: si tratta di regioni H2, ovvero nubi di gas ionizzato dalla radiazione ultravioletta emessa dalle stelle giovani.
Rispetto ai classici ammassi stellari visibili nella nostra galassia (la Via Lattea), NGC 206 è molto più grande, avendo un diametro di 4000 anni luce.
Questa immagine è stata scelta dalla Nasa come immagine astronomica del giorno (APOD = Astronomical Picture Of the Day) per il giorno 28 Novembre 2024.
----------
The image shows a large association of stars in the center immersed in the southern part of the disk of the Great Andromeda Galaxy, 2.5 million light years away.
The association is cataloged as NGC 206 and is composed of blue stars of spectral class OB, therefore very young (less than 10 million years old) and with high temperatures.
On one side of NGC 206, some reddish spots are also visible: these are H2 regions, or clouds of gas ionized by the ultraviolet radiation emitted by young stars.
Compared to the classic star clusters visible in our galaxy (the Milky Way), NGC 206 is much larger, having a diameter of 4000 light years.
This image was chosen by NASA as the astronomical image of the day (APOD = Astronomical Picture Of the Day) for November 28, 2024.

NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7magnitude young central star, SAO 20575 (BD+60°2522). The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel. The star BD+60°2522 is thought to have a mass of about 44 M☉.

My first wide field Galaxy photo, 6 months after getting my first Telescope (a small inexpensive GSO 6" Newtonian Reflector) .
Ancient light from a Galaxy far, far away (situated 11.42 million light years from Earth).
The Sculptor Galaxy, also known as the Silver Coin or Silver Dollar Galaxy (NGC 253), is an intermediate spiral galaxy in the constellation Sculptor. It is a Starburst galaxy, which means that it is undergoing a period of intense star formation (well it was 11.42 million years ago, as the light took that long to reach us).
Recent research suggests the presence in the centre of this Galaxy of a Supermassive Black Hole, with a mass estimated to be 5 million times that of our Sun.
Photographed at the West Rand Astronomy Club's Annual Star Party at Mountain Sanctuary Park (North-West Province, South Africa). A special thank you to Neil Viljoen from "The Telescope Shop" for his assistance.

Object description (wikipedia.org):
NGC 7380 (also known as the Wizard Nebula) is an open cluster discovered by Caroline Herschel in 1787. William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus. It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter.
Located 7200 light years away, the Wizard nebula, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans about 100 light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus). Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun.

M100 è una galassia a spirale nella costellazione boreale della Chioma di Berenice: le sue dimensioni apparenti sono di 7.4'x6.3' e ha magnitudine apparente 10.1.
La sua distanza è di 55 milioni di anni luce ed è stata determinata con precisione dal telescopio spaziale Hubble nel 1993.
M100 mostra due evidenti bracci a spirale con strutture di polveri per tutta la loro lunghezza: il colore azzurro dei bracci indica che sono ricchi di stelle giovani e calde. In questa galassia sono state osservate sette supernove tra il 1901 e il 2020.

Jones-Emberson 1 è una nebulosa planetaria nella costellazione della Lince: è anche conosciuta con il nome di Nebulosa Cuffia per via della sua forma caratteristica.
E' una nebulosa molto debole, infatti venne scoperta solo nel 1939 dai due astronomi che poi le hanno dato il nome.
La stella centrale è una caldissima nana bianca che, disperdendo nello spazio il materiale del suo guscio più esterno, ha formato la nebulosa planetaria: questo gas però è in espansione e tra qualche migliaio di anni si sarà talmente rarefatto nello spazio che la radiazione ultravioletta della stella non riuscirà più ad illuminarlo, e quindi la nebulosa non sarà più visibile agli occhi dei nostri futuri discendenti.
----------
Jones-Emberson 1 is a planetary nebula in the constellation of Lynx: it is also known as the Headphone Nebula due to its characteristic shape.
It is a very faint nebula, in fact it was discovered only in 1939 by the two astronomers who then gave it its name.
The central star is a very hot white dwarf which, by dispersing the material of its outer shell into space, has formed the planetary nebula: this gas, however, is expanding and in a few thousand years it will have become so rarefied in space that the ultraviolet radiation of star will no longer be able to illuminate it, and therefore the nebula will no longer be visible.

NGC 7331 è una grande galassia a spirale nella costellazione di Pegaso: grande sia per dimensione apparente (10,5' x 3,7' - la luna piena ad occhio nudo ha un diametro di 30') sia per dimensione reale (140000 anni luce, quindi più grande della nostra Via Lattea).
Dista da noi 45 milioni di anni luce.
Grazie anche alla sua magnitudine di 10.4, mostra parecchi dettagli sia sui bracci sia verso il nucleo.
Vicino a NGC 7331, nella parte inferiore dell'immagine, si nota un gruppo di altre galassie abbastanza luminose: si potrebbe pensare che siano fisicamente legate a NGC 7331, ma in realtà si trovano ad una distanza circa 6 volte maggiore e quindi appaiono vicine alla grande galassia solo per un puro effetto di prospettiva.
----------
NGC 7331 is a large spiral galaxy in the constellation of Pegasus: large both in apparent size (10.5' x 3.7' - the full moon with the naked eye has a diameter of 30') and in real size (140,000 light years , therefore larger than our Milky Way).
Its distance is 45 milion light years.
Thanks also to its magnitude of 10.4, it shows a lot of details both on the arms and towards the nucleus.
Near NGC 7331, in the lower part of the image, you can see a group of other quite bright galaxies: you might think that they are physically linked to NGC 7331, but in reality they are at a distance about 6 times greater and therefore appear close to the large galaxy just for a pure perspective effect.

そんなにシーイングが悪いって事は無かったのですが、あまり細かな模様が写っていなくて残念。
まぁ大赤斑があるから良いかぁ。

惑星が続きましたのでお口直しにお月様。
この日もシーイングはイイ感じ。
それとやはり赤道儀は画面の回転がないので撮りやすいですね。
撮り始めて時間がたっても構図の変更がいらいないですから。
その関係か今までスタックした際に月の下側が甘くなっていたのですが、経緯台で画像が回転していたからだったのかも、、、
これはもう少し検証しましょう。
あと今回はQuad BPフィルターを使っています。
いつも使っているIR Passフィルターがどこに行ったか見つからなかったので使ってみましたが、画面が真っ赤にならずかえって使い易かったかも。
効果については???です。

観望していた時にはシーイングが落ち着いていて模様がよく見えていました。
300倍ぐらいだと結構楽しめます。
その内に木星表面からイオが出てきたので撮影に切り替えました。
画面で上になっているのがガニメデ、下がイオです。
木星本体で位置合わせをしているので、衛星は伸びた感じになってしまいます。
別で画像処理をして合わせた方が面白そうですね。

良いシーイングが続き白斑の移動する様子がよく分かりましたので纏めてみました。
この永続白斑は合体しながら80年ぐらいは存在しているそうです。
台風なんて数日で無くなっちゃうので、規模が違いすぎますね。
因みに有名な大赤斑はWikipediaを見ると色々な説はあるものの350年ほど存在しているようです。
凄すぎる、、、
