Hey all, so the purpose of this thread is to solicit recommendations for DSO you'd like to observe. I don't know about you, but I've found there's a lot of trial and error involved when I go DSO observing. And unfortunately Netflix and Spotify have not yet developed a recommendations system for DSO based on ones you've already viewed. So I am appealing to the community.

 

The format is simple: someone posts a DSO they liked and want to see more like it, and you try to post one that is the most similar to it. For example, if someone put M11 (Wild Duck Cluster) I would most likely recommend M35 because they are both dense, rich open clusters. For M42, I might recommend M8 (Lagoon Nebula) because it is also a bright emission nebula with a cluster inside it.  It would be helpful to try and have similar aperture and light pollution requirements, as well.

 

To start: I'm looking for more face-on spirals like M51. I've tried for a few others and they were not visible to me.

I would say if you like M51 try M101. It's not as bright as M51 but if your skies are very dark there is a lot of detail to be seen.

If you like M82, try M108 and NGC 2683.

Edge on Galaxies:         

 

 If you like NGC 4565 try ngc 5907, 4517, 5170, 4244, 891,  and 5023 for starters.        

      

If you want a challenge, try NGC 100, ngc 522, UGC 1281, or UGC 711

 

If you have dark skies and a large scope (16" and up ) and want a tougher challenge try UGC 12281, or NGC  3245A.

Oh, good point. It's been a couple years since I looked at this one but from what I recall it was one of the best galaxies I've looked at. I will need to give it another shot soon. Unfortunately its position is not so great at the moment.

If you like the Eskimo Nebula (NGC 2392), you will like its identical twin: Cleopatra's Eye Nebula (NGC 1535). 

 

If you like M51, you will like M64 (nearly identical size and surface brightness with some cool detail to see in it)

To start: I'm looking for more face-on spirals like M51. I've tried for a few others and they were not visible to me.

M51 probably has the boldest spiral arms of any galaxy in either celestial hemisphere. That's presumably because star formation has been boosted in the arms due to the gravitational interaction of M51's main galaxy with its companion.

 

M33 is much bigger than M51, and it too has great spiral arms. But they're much broader, more diffuse, and lower surface brightness, making them harder to see than M51's through most instruments in most circumstances. But boy, when you see them, those arms are grand!

 

M101 is weird. The emission knots in the arms are much brighter than the arms themselves, so it's a kind of connect-the-dots puzzle. Note that Lord Rosse's original sketch had one arm double back at a 180-degree angle -- which needless to say is not actually the case!

 

M83 has a very spectacular spiral structure, but it's too low in the sky to show well in the northern U.S., and a bit marginal even on the U.S./Mexico border.

 

There are also a number of non-Messier galaxies with very prominent spiral arms, most notably NGC 2403 in the godforsaken constellation of Camelopardalis. M81 is great example of an ultrabright face-on spiral whose arms are exceedingly hard to see, especially in less-than-pristine skies.

If you like the Veil Nebula try Thor's Helmet, NGC 2359.

If you like the northern skies, try the Southern Hemisphere!  shocked.gif

 

Seriously now, we have M83 much higher than M51 around here, and the spiral arms in M51 are still much easier to see.  Anyone can see them in the 12" Dob, while it takes experience and a bit of patience to see them properly in M83.

If you like the Pleiades, try the Butterfly Cluster and M47 for more bright, open, low density clusters.

Then try M33 ;)

If you like observing, try dark skies...

 

Face-on galaxy "like" M51 - NGC 1365, the Z galaxy.  That is the only one, other than M51, where even first time observers immediately see the arms. 

 

With experience and patience you can see very nice arms on M83, M101, and M33, but they don't jump out at you.

It's interesting to me how we develop an affinity with certain objects.  This time of year, I make multiple visits to M37, but if you like that object, be sure to quickly catch NGC 7789, one of the most beautiful clusters in the skies.  I have only been observing for a couple of years but I always make a point to visit Caroline's Rose at every opportunity, and love the sense of wonderment it invariably generates.
