M51, M101, M57 in small binoculars
After following a thread on a Yahoo binocular group a few weeks ago
about seeing M57, the Ring nebula, in small binoculars, i wanted to try myself from a darksky site. Last night (Sunday) i was camping/stargazing at the Cottonwood campground in Joshua Tree national park in southern Calif. I had my 10" f/5 dob and Tele Vue 76 and most of the evening was spent using these scopes with my trusty Nikon 10x42 SE alongside to aid in starhopping. Markarian's Chain of galaxies in Virgo is quite impressive with the 10"! Around midnight it was time to take a break from the larger scopes and just sit back and look around with binoculars. I brought 2 other binoculars to compare views with... my little Zeiss 10x25 compact classics and sturdy Leica 10x32 BN. The Zeiss are my hiking binoculars and the Leicas my standard daytime outdoor binoculars. At midnight Lyra and M57 were still fairly low so i started with galaxies M51 and M101 high overhead in Canis Major. The 10x42 showed them both easily. Can just detect that M51 has a companion and M101 is a round soft glow. Switching to the 10x32 the main difference is the background sky is darker with the 32mm objectives. Still, not a bad view at all and both galaxies were easy to see. In fact, the darker background, and bit wider field with the Leicas was almost more pleasing than the view with the Nikons. Finally the little Zeiss compacts. Both galaxies are still easy to see. They don't quite jump out like they do with the larger glasses but the galaxies are "easy" to see through the little 25mm objectives. Around 12:30am Lyra is about 20=B0 above the eastern horizon. I started with the Tele Vue 76mm refractor to confirm the field and make sure what object was M57. (Through the TV76 at 30x the ring shape is clearly visible.) Through the Nikon 10x42 no problem. M57 is easy to see as a "star". I couldn't really tell it was anything other than a dim 8th mag star. Maybe just a bit of a fuzzy star. Also for this, and all binocular observations tonight, i was handholding the binoculars without a mount. But since M57 was low in the sky it was easy to sit and brace the binoculars. Switching to the Leica 10x32 still no problem. The "star" is still there and easy to see. Down to the little Zeiss 10x25, and with a bit more concentration, still no problem. M57 is visible in 10x25 binoculars from a darksite. Easily visible even. It doesn't look like "The Ring Nebula" of course but i wasn't expecting that. I have some more days off this week and will be spending more of them out on the southern Calif desert. The forecast is for a bit of high clouds however. Sigh... -Florian at Stargazing dot com |
