    Mayall -II Observing (sketch /report )

    Hello all ,
    this report is based on the observation done by me on 29th, 30th december 2013 from Coorg , India , Mayall -II or G1 is the brightest globular in M31 , this was my first time attempt on observing globulars outside our galaxy . i also made a quick sketch to confirm it later .

    Instrument used : Discovery 17.5" dob
    Eyepieces : 31mm nagler , 10mm delos .

    day 1: the globular was seen with the neighbouring star and hence couldn't confirm the object even with 10mm delos.
    day2: 31mm nagler showed the two stars , 10mm delos showed the globular between the closely packed star asterism .
    few other objects were observed including NGC404 ,NGC2024, Merope nebula , B33 , Deerlick group , Abell 21 , NGC1999,NGC2261,NGC4490,NGC4631,NGC2359,ngc185,NGC 147 , Hubble's variable , HCG44 , HCG57( only one galaxy NGC 3754 was visible ) ,NGC3359 , and few other common galaxies/nebulae .

    NGC1999 was a surprise , it looked like a halo around the star in 31mm nagler , upon using 10mm delos with averted vision , it showed the inverted " T " shape , which i later confirmed with a image in Cartes Du Ciel. comments welcome .

    Regards ,
    Sanath Kumar

    I tried to see him two years ago but I have not succeeded, would you have a more detailed map so I try again?
    Thank you!

    Hello vesna71 ,
    i have uploaded a photo telling how to proceed , it will be easy if you follow the arrow marks and recognise the patterns to star hop. i hope it helps , let me know if you need more detailed charts .

    Hey Sanath

    The photo seems to be too small. Do you have a way to post a larger picture?

    Also, the finder charts I gave you for this observation are from Tom Trusock's Small Wonders article on Andromeda:

    For G1 you should with a fair sized scope be able to see an almost equilateral triangle with one of the 'points' on the east being G1 and it would appear a bit more fuzzy. The finder I have attached is about a half degree so it's not a telrad but it does show the 3 background galaxies just to G1s east if your scope is 16" or larger they make a curious diversion.

    I went after G1 back in 2012 for the AL Globular Cluster Program pin. I am an addict for those Astro League pins... but anyway...

    The key for me for finding G1 using the 10in SCT was four fold:
    1. Good Collimation
    2. Good Seeing
    3. Highish magnification
    4. Knowing the field/location that it resides in

    It took me three times to see it for sure with my 10in SCT (saw easily with a 18in Obsession though). There are lots of pictures and charts out there, do some google searching and you can find one to your liking. I looked at a picture of the field so many times while researching G1 to observe over those months that I got to where I knew that field from memory.

    Hi all ,
    i was curious if anyone here has been able to resolve stars in G1 ? ( is it even possible if seeing is very very good , like in Chile ) .
