M27 is an exceptional binocular object. It is one of the few planetary nebulae that are recognisable with a pair of binoculars. Point your binoculars at Gamma Sagittae (yes, the tip of the arrow) and shift your field of view 3 degrees to the north. M27 should appear in the upper part of the field of view. Look for a fuzzy spot just south of a mag 6 star. I found M27 brighter and easier to detect than M71 in Sagitta. My 15x70 binoculars actually showed a rectangular brightening, its long axis running from NNE to SSW. M27 is a nearby planetary nebula with a distance of around 1150 l-y.

Rony,

An excellent observation of the Dumbbell Nebula (M27). You have captured this ghostly shell of a star very nicely. The star field rendered is exactly what the observer will view. Thank you for sharing it with us all.

Carlos

Rony,

This sketch like all the others you have posted recently is just beautiful. Your capture of the wide field and care in placing the stars and matching the brightness of each is just amazing. Beauty and precision in sketching are your forte. :bow: :rainbow: :bow:

Frank :)

Stunningly beautiful Rony! :bow: :jump: :bow: Another Binocular Icon masterpiece. I love these wide field sketches, they are so realistic that I feel as if I am in Bekkevoort, peering through the binos along side of you my friend! :D

Rony,

Excellent capture. A question and please excuse me if it has been asked. Are you doing the sketching of binoculars as a personal project? The only reason I am asking is that I think these would make an excellent rendering in a book for those using binoculars. I know you have your website but I think when your done capturing the Messier in binoculars you should publish them!

That is a really pretty sketch Rony. I was thinking of you the other night when I was using the sky window in the SSW looking at the Sag. area. I don't recall you sketches from that area. Of course, it sure is dense with stars and objects so I will have to pick and choose carefully. I think I want to do the Lagoon with the window because the cluster is so beautiful in binoculars. I'm not nearly as good a sketcher as you on binoculars, but am looking forward to another clear night in the area to give it a whirl. Roland

Thanks for the fine words, guys!!

Roland, I have a few observations of the Sagittarius region:

Messier 8

Messier 22

Here are a few nice objects nextdoor in Scorpio:

Messier 6

Messier 7

These milkyway fields are really dense with stars and the bino's to take in a lot of sky, so you better sharpen those pencils of yours.
I look forward to your sketches, Roland. :)

Excellent rendition of M27 through binoculars. :bow: :bow: :bow:

All of your wide field sketches are superb. They remind me of my first nights with a new pair of binoculars in the mid
1960's as a young teen laying in my parents front yard at the edge of Portland Oregon. Your binocular sketches rekindle my memories of first seeing these Messier objects, as I just looked at your extensive list of other images.

All of your your sketch work is a great learning tool for others to see through, aside from also inspiring veteran astronomers and artists.

I like the way your sketch makes me feel - like I'm looking trough the eyepiece. Very impressive =)
Also you made the nebula look really faint, like it's supposed to be.

Well done, Rony. I observed M27 through various instruments at the Green Bank StarQuest including my 12x36 image stabilized binoculars. Your drawing is an excellent rendering of the binocular view. I locate it like you do--coming off the tip of the Arrow. BTW, I think you'll find M27 a little brighter if you can revisit it at a darker site.

Dee, Michael & Michael,

I'm glad you like the sketch.

@ Michael Rosolina : Michael, that's correct. The conditions were not perfect during these midsummer nights. It's also a proof for the fact that M27 is a very bright object. :cool:
