Another challenging galaxy

Posted By Dave Mitsky
Inge,

There are no IAAC reports on NGC 4395, which apparently is the nearest Seyfert galaxy and which has the smallest black hole (only 300 to 400,000 solar masses) yet detected.

There's a sketch of NGC 4395 that was done with the aid of a 6" f/6 Newtonian at http://www.bert.dekker65.freeler.nl/frset_gal.htm

Propellor "asterism" in M13

Posted By Dave Mitsky
It's been my experience that the Propellor is easier to see with larger apertures and higher magnifications.

We had a very good time, and the views on the H-alpha field were very, very good. Paul's double stacked Traveler was particularly good.


Indeed it was.

That is a superb image of Jupiter and two of its satellites, Russell.

Posted By Dave Mitsky
Several years ago I was very nearly lased by some idiot at Stellafane. Last year at the Black Forest Star Party, where GLPs are banned, a friend of mine was not so lucky and was accidentally struck in one eye with a beam from a green laser collimator. He is still having problems with his vision in that eye.

NGC 5248 Observation

Posted By Dave Mitsky
That's an excellent sketch, Vincent. NGC 5248 is on the Herschel 400 list and is a rather nice galaxy. My IAAC report on this object can be found at http://www.visualdeepsky.org/netastrocatalog/msg01473.html

There's are good photos of this SAB(rs)bc I-II galaxy at http://www.noao.edu/outreach/aop/observers/n5248.html and http://www.rc-astro.com/galaxies/ngc5248.htm

PST?

Posted By Dave Mitsky
Double stacking will reveal more detail in the chromosphere but I've been perfectly happy with the performance of my stock PST. It is truly one of the best buys in astronomy gear.

32mm UO Konig?

Posted By Dave Mitsky
I've used a 2" U.O. 32mm Koenig-II for many years while observing at the ASH Naylor Observatory. It should work just fine in an f/10 telescope.

Leo 1

Posted By Dave Mitsky
I've observed Leo I a number of times, always from dark sites on good nights. I've also seen Leo II once through a 25 inch Dob. It was a considerably more difficult target.
