While a few of Sharpless's entries, such as Sh2-25 (better known as M8, the Lagoon Nebula) and Sh2-49 (M16, the Eagle Nebula), are well known to visual observers, most are among of the most challenging objects to see visually.If you have never made a concerted effort to see some of the lesser known Sharpless objects, then this challenge, Sh2-301 in Canis Major, is a good introduction to the sport.

Uh - this one's getting a little low for me. Still going to give it a go, though.

Thanks for sending me on this challenge! I wheeled out my 12" Meade LX200 classic with an Orion ED80 on top, added this as a user object put in the RA and DEC and gave it a shot. Using a ZWO ASI174MC camera with a 0.7 focal reducer and Astronimik CCD CLS filer I was disappointed to not see anything unusual on my laptop screen with 90 sec exposures and gain at 270. so I only took about 20 exposures and moved on to something that I thought would be more rewarding. And since I live under Bortle 8 skies (North East New Jersey, only 16 mile to Times Square) I figured this elusive challenge object was a bust. But once I processed my images (only in DSS) and this nebulosity appeared in front of my eyes I was truly amazed. So thank you as being able to see this in the sky glow on New York City give my passion a little more excitement.

Amazing what can be done thanks to the magic of post-processing, isn't it?  Nice capture!
