Kemble's Cascade (binocular observing)

Hi all

In the astro-weblog I started a new series of articles called "My
favourite binocular objects". In this column I will regularly post
interesting binocular objects with finder charts, sketches, images
etc. I started with Kemble's Cascade, an asterism in Camelopardalis.

Nice site! As soon as it gets dark, I'll be outside with my Oberwerk 22 x
100.
One question: You say on the website that the brightest star in the Giraffe
is Beta. What happened to Alfa, or how come Beta is brighter than
Alfa???????
Keep up the good work!

in the Bayer system, alpha should be the brightest. it is based on visual
observations, and when the magnitudes are close, the designation is not
always accurate.

Hi Stefan,

I just checked my star atlas. Alpha has a magnitude of 4.29 while beta
has a magnitude of 4.03 (both visual magnitudes). So beta is the brightest!

Clear skies

I'm a little amazed that they are able to descide the visual magnitude down
to 0.01. What is the human eye able to register? Do we see the difference
between 4.29 and 4.28? Or 4.3 and 4.2?

Regarding the subject: The rings are the topic of my 21:19 posting.
Sorry about the confusion.
