Probably known better by its nickname the "Intergalactic Tramp" bestowed by Harlow Shapley in 1944, NGC 2419 is unusual among winter's deep-sky objects for many reasons.

Thanks Phil for the excellent sketch, star hopping directions and write-up for NGC 2419, an object I haven't viewed yet. Brad

It looks like this is indeed a really tough challenge.

Nah, not really. It depends heavily on the sky, though. I've seen it in a 2" f/17 refractor from a dark sky site without much trouble, and also in a 60mm finderscope at just 10x. At that low power, it really is quite challenging, but in the 2" at 30x, it's pretty straightforward. 

 

 

Clear skies!

YIKES! This one's gona be interesting... My 36-inch scope goes operational late April (hope!). So I will hope to be able to see 2419 maybe, just maybe... as something more than a fuzzy? Nice and high for us Northerners, too! Thanks!  Tom

With a 36", you should be able to resolve some stars - or perhaps many. On the very best nights, I can see a hint of mottling in my 12" at 200x, though this might be a sprinkling of foreground stars in front of the cluster or tiny groups of unresolved stars.

Yes, indeed. I'm all excited about the 36 and this will be a great test of its capability. Hoping the views will be... decadent!  [luxuriously, lavishly self-indulgent].  Tom

Thanks Phil, for the interesting writeup and the challenge. I've only see this DSO one time, on April 21, 2011 in a dark sky before Moon rise, seeing fair to good. 

 

Celestron-11, f/6.3, 160X (11mm Nagler, T6)

 

Here's the note in my observing record:

Remote globular cluster in Lynx; mag. 10, ~5' dia., at end of line with 2 roughly 4th mag. stars; with close scrutiny can see around 1/2 dozen very faint stars; brighter glow in center

 

For the last 10 years I've been using a go-to mount. But I don't feel bad about that after using star atlas and finder 'scope for the previous 40+ years. My old neck and back appreciates the hi-tech help.

Phil:

 

Thanks for the write up and for the challenge . They always add something extra special to an evening. 

 

This has not been a good month cloud-wise so my only chance at observing 2419 has been with the moon nearly full from an otherwise dark site. I was able to detect it with my 12.5 inch under the full moon,  i figure I should be able to see it from red zone backyard on a moonless night. 

 

The saga will continue. 

 

Jon
