  1. Well I had a crack at the Nova last night and managed to pick it up. The pics are more noisy than I expected but that could be down to the Moon? Anyway, this is the first batch I have processed and there are a couple of other things going on. I believe the Dumbell galaxy can even be seen to the right.
  2. The nova in this image is the bright 'star' just above the red marker characters. (correct vertical frame with N up for binoculars) This image taken from Kelso, Scottish Borders during the bright waxing gibbous Moon. 1.00am BST 19th August 2013 Canon 60Da with telephoto lens @ f16 5 x 180sec @ iso100 Flat Frames Dark Frames Bias Frames Nova Delphini 2013 by mikeyscope, on Flickr
  3. A clear but 'nothing to write home about' type of sky was good enough to warrant a session but my expectations were not high. The Milky Way was barely detectable and the feintest star in Ursa Minor occasionally flickered out of view. A good 0.5 or 0.6 of a magnitude from perfect (for my back garden). First up were a couple of small planetary nebulae. NGC 6803 in Aquila proved harder to star hop to than I imagined. It was easy enough to see but at four arc seconds looked stellar. Similar but slightly feinter was NGC 6879 over the border in Sagitta. An easy star hop from Gamma Sagittae, through 13 and on to 15 and just beyond. Both of these need a bit more aperture and magnification to be viewed with any detail. North again to Vulpecula and another easy star hop to NGC 6802, an open cluster at one end of the Coathanger. The cluster forms an equilateral triangle with two feint pairs of stars at the Eastern end of the Coathanger. Given its magnitude and surface brightness (8.8 and 11 respectively), I expected it to be quite condensed but was dissappointed to find it nothing more than a soft glow, barely detectable. The globular cluster NGC 7006 (Caldwell 42) in Delphinus was perhaps the pick of an obscure bunch. This again, is quite easy to find, just East of the head of the dolphin. Initially, I struggled to see anything but a prolonged stint at the eyepiece showed a circular haze with averted vision and the core was just visible directly. I was unable to detect the galaxy NGC 7814 despite being certain I was in the right area. This is very close to one of the four main stars of Pegasus and so given a clearer night, I should be able to see this in the future without wasting much time locating it again. Last up was NGC 2300, another galaxy close to Polaris but just inside the realm of Cepheus. I couldn't see it conclusively with the 15mm eyepiece and speculatively moved up to the X-Cel 8mm. The extra contrast more than compensated for the extra magnification (79x) and I found it reasonably easy with averted vision. The nearby galaxy NGC 2276 proved too feint for my equipment / ever ageing peepers. As I gradually exhaust the list of DSOs I have set myself, the likelihood is I will have to move onto some sketches. It is nice finding more difficult objects but they are getting ever less rewarding to view. I just need to sort out a comfy seat. __________________________________________________ ______ Observing Session: Wednesday 10th October 2012, 20:00 hrs to 22:10 hrs BST VLM at Zenith: 4.9 to 5.0 New - Revisited - Failed
  4. Heres 12x RGB 60s of the Nova in Delphinus. ATIK428EX on the ED80. Just a quick one to get an image in.
  5. Cleared up nicely as forecast last night so I had a crack at the nova in Delphinus. Www.mattastro.com/delphinus_nova.html 1000d + Ed80 10x 2 mins, ISO 800
  6. It's been a such a long time since my last session, I thought I may have forgotten what end of my scope I was meant to look through. Thankfully it all came flooding back. The sky was not great to start with and I was in a hurry before the Moon lit the sky up. I started with a return to M57, the Ring nebula. Easy to find without maps and a rewarding view. At 42x magnification, the hole was quite clear and at 80x the ellipse became more obvious. I would definately rate it as a top 20 object for beginners as it is tolerant of light pollution. I then turned my attention to the East side of Ophiuchus and two globular clusters. Just to the Northeast of Nu Ophiuchi and almost in line with the fifth magnitude Tau Ophiuchi is NGC 6517, a small 10th magnitude glob with a supposedly high surface brightness. Unfortunately the quality of the sky at that elevation resulted in an inconclusive attempt. A little further Northeast, beyond Tau Ophiuchi, is NGC 6539. This larger and slightly brighter cluster was just about possible but was nothing more than an averted vision dirty mark. The final object I viewed was the small planetary nebula NGC 6891, in Delphinus. It appears as one end of a V-shaped asterism of stars between magnitude 8 and 10 to the West of the famous diamond head of the dolphin. With maximum magnification of 126x it could just about be identified as slightly less stellar that the nearby stars and possibly slightly elliptical. My scope struggles a little with sharpness at that magnification. A longer focal length would go a long way with this one as its surface brightness is such that it could take substantially more magnification. It's good to be back and a couple of new finds in a short session was satisfying. __________________________________________________ ______ Observing Session: Wednesday 5th September 2012, 21:20 hrs to 22:15 hrs BST VLM at Zenith: 4.9 - 5.0 New - Revisited - Failed
  7. The constellations, they can be filled with beautiful objects for us to observe.Popular constellations such as Orion, Monoceros, Canis Major and Puppis all host beautiful nebulae and star clusters along with gorgeous binary and variable stars. Every constellation has it's charm, but some just don't get the spotlight. I'm talking about the underrated constellations. These include Equuleus, Canes Venatici, Leo Minor, Sagitta, Vulpecula and Lynx. But my personal favorite, Delphinus the dolphin. When I looked at DK's " Astronomy " book ( Fantastic book and guide for beginners I highly recommend ) In the constellation section where it gives a detailed description and the history of the constellation it also notes some objects of interest too. Delphinus only had one, Gamma Delphini which is a great golden binary with an 8.9 arcsecond separation in the nose of the dolphin. But this of course isn't the only object of interest in Delphinus, I have been exploring it the last few evening in my telescope and binoculars and I found some very interesting things. Enjoy Our first object other than Gamma Delphini is a nice open star cluster with no name I came across myself, it is composed of 6th and 7th magnitude stars the brightest being Omicron Dephini at magnitude +5.85. To locate it, find Rotanev ( Beta Delphini ) and find Deneb Dulfim ( Epsilon Delphini ) draw a small line line to the left of Rotanev. Then draw a line vertically from Deneb Dulfim, the point where these to lines meet is very close to the location of the star cluster. Next we have NGC 7006 and Caldwell 47. Two very nice globular clusters for large telescopes. Have you ever looked at Delphinus through 7x50 binoculars? The entire constellation fits in the optics, meaning you can have a look at all the stars that make up this beautiful constellation! It looks alot like a big open star cluster! That is my list of objects I discovered through my adventure in Delphinus, my favorite underrated constellation. Please tell me yours and some of the objects in it! Thanks Adam
