   Continue my journey through Lyra, it would be a shame if I forgot to include this wonderful star. Located just 2 degree from the brilliant star, Vega. Once you center T Lyrae in the eyepiece it gonna be an unforgettable sight. That was exactly what had happened to me when I first ever successfully bagged this one with my 6 inch. Acted as my first ever impression about a carbon star, T Lyrae had done an excellent job in introducing me into this amazing world of carbon star. 

 

   Recently, I "re-observed" this star on many occasions. But only 3 nights that had the strongest imprint in my mind.

   The first night was the night that I returned to T Lyrae after 2 full years. I filled with nostalgic; it still looked crimson red like 2 years ago but was considerably better with a wide field instrument. 

   The second night was the night that I made the sketch below. It was also the worst night because of thin haze. NELM barely reached 3 on that night. But T Lyrae still shined through. I compared its magnitude with other stars' and estimated T Lyrae was mag 8 near 9. The color I recorded on paper was vibrant red. I even gave it a nickname "Hidden Ruby of the Harp".

   The final night was last night. The sky seem to improved a little bit but distant clouds threatened any prolonged observation. So I was just mostly toying with the binocular and take a last look at this star and M57 with the 80mm scope before went to bed. It still looked gorgeous at 19x with all of the surrounding field stars. 

 

   I include 2 sketches the original and the digitized one. I use an 80mm f/5 refractor at 25x for the sketch. Any stars that showed color have a small letter near them in the pencil sketch. Sketch then got digitized using Photoshop. 

 

   Hope you enjoy the sketch, thank you for reading and Clear Sky waytogo.gif waytogo.gif waytogo.gif !!!

I was not aware of this “hidden ruby of the harp” carbon star but now it will be my first target when I get my FS128, I’m sure it will be an amazing sight, thanks for posting.

Tien,you continue to set a fine example of getting the most out of modest equipment in surroundings awash in light pollution. Another fine rendering and post.

Hello Tien Tran. 

Magnificent sketch of T Lyrae!

This was my first ever observed carbon star. 

I observed in December 2000 and I have seen it since. 

Today I rarely observe truly red stars. 

That's because I own a triplet apochromatic refractor.  

Carbon stars are rich orange always - except I found a ripe tomato red a few months ago. 

It's called S Cephei. 

Maybe you could check it out at some stage. No pressure!

 

Clear skies from Aubrey.

   Thank you for all of your kind worlds flowerred.gif flowerred.gif flowerred.gif  !!! I appreciate them all. Light pollution steals a lot of charms but not all. It's good to see objects like this star still easily accessible through the veil of murky sky.

   I found out that the orange color in a carbon star is more evident with increasing magnification. I don't know how but I think it must be the sky brightness in the background. That was why I only used 25x for the sketch because higher than that T Lyrae showed some significant orange hue. 

   Thanks for your suggestion on S Cephei. But it is too low from my location; it barely reaches 22 degrees from here. I have to save this one when I have a clear view of the Northern sky. 

   Thank you for your comments and Clear Sky to you waytogo.gif waytogo.gif waytogo.gif !!!
