In the suburbs. For DSO. Do you choose 15x50 or 18x50 ?

The 15x magnification will offer a wider Field of View than the 18x binocular.  That will make it easier to find the object.  The difference in magnification is minimal.

My choice was the 18x50, I found that extra bit of magnification added a lot to most open clusters. Plus I like the smaller exit pupil in the burbs.  Makes the sky look darker.  I guess one of the influencing factors for me is that I had the 10x42L already and I felt the 18x50’s optical parameters provided greater differentiation to what I already had.

 

I don’t think you can really go wrong with either one.

Just saying, I love my 18x50's.  How many hand held binocs reveal the rings of Saturn.

The Canon 15x and 18x are both excellent IS binoculars but my choice for DSOs would be the 18x because it offers a bit more resolution and sky darkness. Also, it's a nice complement to my 10x42L. I use all binoculars in a reclining lounge chair with arm rests. With practice, you will get better at aiming the 18x and holding it steady. The 18x Canon displaced my Fujinon 16x70.

The 18x50s will show a bit more. If you have astigmatism, the smaller exit pupil may be an advantage. 

 

Clear skies, Alan

I am wanting to use them while standing. I hope the 18x50 is somewhat similar in effort to the 15x50.

If you want to use them fee standing I recommend 10x42. Leaning 15x50. Sitting 18x50.

 

[Corrected typo 10x50->15x50.]

Not worth the cost to me for 10x. Will either be 15x or 18x.

How old are you, how strong, how much experience holding high magnification binoculars?

40. I do well holding 10x50' Bushnells. My sessions are 30 to 60 minutes usually.

I've used both, and preferred the 15x50 for it's wider FOV on star fields. There's no bad choice here...

Not sure what are good prices for these. Do they go on sale often?

They come up fairly often on astromart.  I picked up a nice 18x50 for $600.

The 15x are typically the least expensive of the 3 new. Sub 1000 is a good price. Sub 900 possible when eBay runs coupons etc.
