By constellation:



WZ Cas (Variable star)
Also known as: WZ Cassiopeiae
Right ascension: 0h 1m Declination: 60° 21'
Constellation: Cassiopeia
Date/time: 2008.01.21 19:00 UT
Equipment: 12" f/5 Newtonian
FoV: 6' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Probably this is the most beautiful orange-coloured star I've ever seen. Located nearby the bright ß Cas, the star B of this binary has a colour index of 0.03 while star A has 3.12 which means that this is an extremely red star. The WZ Cas is a red giant star that is also a variable. Its colour can be best seen in magnifications under 100x.

T Lyrae (TVICS)
Also known as: T LYR
Right ascension: 18h 33m Declination: 37° 5'
Constellation: Lyra
Date/time: 2012.08.14 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: 14' Magnification and filter(s): 250x
Seeing: 7/10 Transparency: 4/5
SQM: 21.2 m/as2 Temperature: 6°C
Humidity: dry Wind: none
Sight: 5 - plentyful of details, a must see object, jaws dropped
Difficulty: 2 - easily visible, some dark adaptation needed, averted vision might add to details
Position: 3 - moderate, some starhopping needed
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

When I first glimpsed this star, my jaws simply dropped and I regret, but the first thing I said was "oh f*ck". This is most probably the reddest star you can ever find. Everything I ever saw is surpassed by the looks of this star, although WZ CAS still rules the world of colourful stars with its nicely contrasting blue companion star. This variable star is a lonely one, and with its beautiful colour it's also an easy find, although it is a bit faint and you must prepare yourself for finding something in the FoV that is not a shade of white: interesting, but this uniqueness makes it a bit hard to find for the inexperienced eye!

This star is a MUST see object!

Faint, lonesome red variable star with a touch of orange. Two fairly bright stars located nearby to the W and NW, making a nice triangle with AX CYG. To the NE (outside this FoV) there's a binary that looks colourful too. Despite its faintness it is a very remarkable view.

WZ Cassiopeiae (TVICS)
Also known as: WZ CAS, Hip 99
Right ascension: 0h 2m Declination: 60° 26'
Constellation: Cassiopeia
Date/time: 2012.09.07 20:25 UT
Equipment: 4.5" f/8 Newtonian
FoV: 8' Magnification and filter(s): 224x
Seeing: 8/10 Transparency: 4/5
SQM: 21.33 m/as2 Temperature: 10°C
Humidity: low Wind: none
Sight: 4 - lots of details, very interesting, unique look
Difficulty: 1 - instantly visible, no dark adaptation or averted vision needed
Position: 3 - moderate, some starhopping needed
Location: Lipótfa, Zselic, Hungary
Observer: Ferenc Lovró
Description:

One of my favorite variable/binary stars. I've found it years ago just by wandering on the sky with my telescope, and it was very easy to notice it because of the beautiful red colour of the primary star. The companion has a bright blue colour, contrasting very nicely with the primary. Their luminosity is nearly similar, they resemble me of a miniature Albireo. In fact the diameter of the FoV was about 1.5 times as large as displayed, but the sky was so dark that it was hard to see the border of the FoV in the eyepiece.

Mu Cephei (TVICS)
Also known as: Herschel's Garnet Star
Right ascension: 21h 44m Declination: 58° 51'
Constellation: Cepheus
Date/time: 2012.09.12 00:00 UT
Equipment: 12" f/5 Newtonian
FoV: 14' Magnification and filter(s): 250x
Seeing: 7/10 Transparency: 3/5
SQM: 21.22 m/as2 Temperature: 10°C
Humidity: dry Wind: breeze
Sight: 3 - definite details, interesting look
Difficulty: 1 - instantly visible, no dark adaptation or averted vision needed
Position: 1 - very easy, many bright stars nearby
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Beautiful golden star also known as Herschel's Garnet Star. With its high luminosity it dominates the field. As it is easily visible also with the bare eyes, it's a very easy target. If T Lyrae is unbeatable in redness, this star is probably the winner in the golden category. This star is actually one of the brightest known stars, a supermassive giant nearing the end of its life. How sad.

Position: 4 - hard, complex starhopping needed
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Surprisingly faint yet very spectacular carbon star. It's a bit difficult to locate, but worth taking a peek. It has a colour of deep red with a very little orange in it.

Difficulty: 4 - hardly visible, dark adaptation and very dark skies needed, averted vision is required to see details
Position: 4 - hard, complex starhopping needed
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This star lies in a field rich of stars, but clearly stands out of the crowd with its faint orange dominated whiteish colour. OK, I agree that its colour is unimaginable based on this definition, so I guess you will have to see it yourself. Quite difficult object thanks to its field and faintness.

KIC 8462852 (Variable star)
Right ascension: 20h 6m Declination: 44° 27'
Constellation: Cygnus
Date/time: 2015.11.01 17:45 UT
Equipment: 12" f/5 Newtonian
FoV: 12' Magnification and filter(s): 250x
Seeing: 7/10 Transparency: 4/5

This average-looking star hides some secret: it has a rather unusual light curve that riddles astronomers. Most probably a large swarm of comets occults the star here and then, but some believe this star may be the home of the first evidence of extraterrestrial activities: a Dyson-sphere under construction.
