NGC 1569 is THE 'planetary nebula' of Galaxies!

[Scott Harrington]

Okay, what I mean by that is it takes magnification like a champ...and like some of the best planetary nebulae, reveals something with every one magnitude jump in aperture, too. So, for example, the super star cluster A1/A2 is visible in my 10-inch at 400x. Go to my 16-inch and at 440x, the super star cluster B is now also visible. And I'm guessing that if I were to catch the galaxy early in the evening next April (TSP 2026) with Keith Rivich's 25-inch, the young massive cluster '#10' would be visible.

Image from (https://www.astrode.de/ngc1569.htm) with the author's own labels of the objects of interest that he saw at 813x in a 48-inch!

I'm taking a moment to mention all this because it was the last object Jimi let me, along with Paul and Debbie Alsing, look at before shutting down for the night early on October 22nd (we were all leaving 10 hours later). And I'm thankful for that since not only did it allow me to use 813x to nab the third brightest cluster (a young, possibly massive cluster known as #10 in the discovery paper by Deidre Hunter et al. (2000), but also the fourth brightest cluster (an older but large globular cluster known as #30 in that same discovery paper). That cluster was hard to see, but clearly seen once I figured out that the star about 9" NE of it was brighter.

I didn't get to see a lot of what I had hoped to go after with Jimi's 48-inch because the seeing was never that great and a lot of my objects were morning objects. But having my very last object be one that revealed so much has really helped me to not dwell on the things I didn't observe. So, please, do yourself a favor and next time the seeing is holding steady, hunt down this little oyster of a galaxy and see how many pearls you can pry out of it!

NGC 1569 is one of the best planetaries, you are right Scott.

 

I remember fighting for the separation of A and B with my former 16", but finally I had success.

With the 27" the separation was easy and lots of other SSC's become visible. Seeing was only average and transparency of a rural sky. I could not see GC 30 but could separate 10.

Wow, thanks for sharing your two sketches, Uwe! I always appreciate it when you do that. You did indeed see everything that I saw in Jimi's 'scope except GC #30. Impressive! And that lends weight to my idea that #10 can be seen with more modest-sized aperture. I wonder if a 20-inch could see #10?

I had this on my observing list for October with the hope of seeing the two SSCs, alas I had to make an urgent trip back home to India.Maybe in November!

Uwe thanks for your notes.
