Sharpless 2-27 with Iridium Flare


Recommended Posts

Sharpless 2-27 is very large nebula centered around Zeta Ophiuchi. Very difficult to photograph due to its size and brightness, it is over twenty Moon diameters wide and very faint. Film and detectors well equipped for Hydrogen-Alpha (Ha) imaging reveal it best. I consider it one of the greatest objects in the Milky Way.

Located on the Milky Way's border in Southern Ophiuchus and partially overlapping into northern Scorpius.

Pentax 67 with SMC 200MM F/4 @ F/5.6 60 minutes expose on Kodak E200 transparency film.

Hi Tom. Notice how the flare starts, dim and then gradually brighter and then gradually dim again. Also, the flare is oriented due east - west exactly. Almost all my images are oriented north-south vertically oriented to within a degree. And if that doesn't convince you, I have another image taken the following night within the same hour that shows this same satellite flaring in the almost exact same location!

I'll check out your image.

      Hey guys. For. A while now, i have been wondering, just how much difference does a dark sky make. I live in moderate light pollution, as i live in the city.The orion nebula is just a little fainter than most stars when viewed with the naked eye.
      The limiting magnitude for my 8" dob so far(that i have tried) is 8.4. i could just make out the crab nebula at 37.5x . extremely faint and just visible with adverted vision.I can also see the blackeyed galaxy quite clearly.
      I will be going on holiday in the summertime.I ll be visiting a place with clear dark skies.I will bring my 5" Skywatcher heritage with me. How many inches of aperature will the dark skies"add" to my scope compared to its original aperature at a light polluted location.Will it be able to rival my 8" dob?
      Just wondering
      Clear skies

      Hi there, our Astro group were booked into our normal dark skies venue for an observing weekend in February.  Unfortunately, the accommodations are now going to be undergoing renovation and will be closed for the first 3 months of the year.   We are looking at a couple of alternative venues.  These are field study centres, one at Blancathra near Keswick and the other Malham Tarn in the Yorkshire Dales national park.  Wondering if anybody has  any observing experience of the skies in these areas.
      Kind Regards
      Paul.

      Hello all. I've been preparing for the long dark winter and sorting out a plan to maximise my viewing time. Using a map of North Wales and the Dark Sky website I am trying  to find a reasonable dark safe site to view within a one and a half to two hour journey time from the St Asaph area.
      Does any member know an area that can be recommended?. I was looking in the area of Lyn Brenig near Denbigh. If any site is sensitive i.e. not wanting to draw attention to it I would be happy to receive a PM if any member does not want it broadcast. Thanks for reading
