Glimpse of G1 in Andromeda

#1

Post by helicon »


I did manage to take a peek at M31 last night through the 10" Dob. I hauled out the scope because the galaxy was a naked eye object. Seeing was very good so I attempted the globular cluster G1 (also known as Mayall II) which I think I nailed down at 220x, though it was a fleeting spot. It is estimated to be twice the size of Omega Centauri and the most prominent globular in the local group of galaxies including the Milky Way, Andromeda, M33, etc.

Finding it is fairly straightforward. First center your telescope on M32, and from here move to the 5th-magnitude star 32 Andromedae. Star-hop another 1.5 degrees to SAO 53986. Then sweep your eyes down...

Confirmation may be achieved when you see the two stars that flank G1. (Using a photo to zero in can be helpful). See the attached Hubble image.

Sure is a nice catch Michael!

I’ll have to take your word for it though. I’m sure I will never spot it from my Bortle 7 backyard and 5 inch newt!

I tried looking for G1 in a recent image, but it is way out of the fov.

Congratulations!

Nice Michael - thanks for sharing that.

It astounds me that we can see a GC attached to another galaxy. I highly doubt I would be able to nail it from my yard. If I ever get out to the club site, I will have to give it a shot.

This is way cool! Thank you for the report. I second (or third) this for a VROD nomination.

And thanks for the inspiration. This will make an interesting light-of-the-moon photo target. It should be about 25 pixels across with my gear, so I'm going to go for it.

Hi MIchael. A nice catch of G1 with the 10" Dob. An excellent report Michael and your "road map" to find it when star hopping is very handy. Thanks for sharing this with us Michael and congratulations on receiving the TSS VROD Award.
