Re: Comet I2 Borisov

Very nice. I had a shot at it from home in Oregon a couple nights ago and found it but the weather here shut me down. We are still not up and running at DSNM but should be in early December.

Interestingly, for those with TSX systems, until just a week or so ago TSX would not accept Borisov because they had not allowed for eccentricities above 2. They finally fixed that oversight with a daily update.

Greg,

Nice catch. It took me a while to find the comet. Thanks for sharing.

Hi all:

The "interstellar" comet I2 Borisov has brightened a bit and now has a defined tail:

Brian,

 

Looking good especially with the moonlight which would have been near it? I’m glad it sounds like you’re getting your mount where it needs to be. I was a bit bummed when you mentioned having issues.

 

Do Tally and MJ share the setup in the building next us? Met Tally when I was down last time but it was after dark and I know how it is when you’re trying to get things going so I didn’t want to encroach on his time. I think I tried reaching out through flickr or something like that to get him to join this group but I don’t remember getting a response.

That’s a great Whale shot, Bernard.

 

When at DSNM, I found that I had never retightened the wedge under my Planewave L-350.  So the slight flexure was probably most of the source of my poor tracking.  Also, PW told me to look at the ground wire at the board and I found it to be rather loose (could have caused my occasional mount communication drops).  So my trip was successful.  Met newcomers Tally and MJ from Boulder.

 

I was able to get 210 minutes on the Sculptor Galaxy in the moonlight.  About half 5’ exposures, about half 10’ exposures (all unguided).

Hi,

This is an image of NGC55. Wikipedia says this is called the Whale Galaxy, but I am pretty sure that is more commonly used to refer to NGC 4631. Perhaps the Southern Whale galaxy. It is a barred spiral galaxy about 7 million light years away in the constellation Sculptor. It is one of the closest galaxies in the local group, which is the group of galaxies that we reside in.

Comments and suggestions are welcomed.
