  1. All set up to go with the sole aim of getting some Saturn images! To start off it was Jupes again to get some imaging done... The GRS superbly placed and looking Redder than a lidl tomato (subliminal advertising) After capturing some film it was time to properly align using Polaris and that wonderful on ya knees polar scope method!!! Boom!! three calibration stars and 'GoTo' whatever you wish for! Cygnus time - Check sheets and then give up and go and fetch Sissy Haas bible... 20 lovely doubles, not rushed just enjoyed and studied hard... working with my Starwave f/11 102 and for those difficult ones a 6.5 Meade HD and even with the 2.5 Revelation Barlow gave interesting views... 200x the recommended max mag on that Starwave, I squeezed more than that out of her. The stars looked round and colourful the companions sometimes hard to spot... But there's a great deal of satisfaction when you see them close by. I made some star symbol notes in the book when a true double of beauty made me smile, my top few were: Σ 2668 Superb 26 Gyg lovely 17 Cyg 19 Cyg Bright Red Ψ Cyg Σ 2687 Sharp 49 Cyg Faint 48 Cyg Wide H IV 113 Spot on (why did I write that?) 61 Cyg Nice Also - Σ 2760, 59 Cyg, 52 Cyg, O Σ 410, Σ 2705, Σ 2588, S 726, Σ 2578, 16 Cyg, δ Cyg So that's my haul for the night... By the time I had finished those it was 01:30 and cloud had covered what was left of Saturn. The great thing about that session was that I didn't have those long whiney scope movements around the sky, it was all within the constellation. I expect my neighbours with open windows were also grateful. Love that 102 f/11 Starwave scope.... A lot of the comments in Sissy Haas recommend a 150mm for some of the hits I made with my 102 so I'm happy... to get the colour is special as well... Not sure my alignment was that great because after entering RA & Dec the doubles were not always centered which resulted in me having to move towards the nearest double looking star a lot of the times. Didn't get -19 Cyg or T Cyg although I tried... Oh and on editing my images I notice I bagged both Europa and Io.... shame Jupiter disappeared behind next doors roof before the shadow made a transit! I've had to lighten one image to show the moons so beware you professionals

    Veil nebula

    From the album: Widefield DSO

    A first pass process of this. OIII as blue: Canon 600D, EF 135mm f/2L, Astronomik OIII filter, 21x 2m. Ha as red: modified 450D, EF 135mm f/2L, Astronomik Ha filter, 18x 2m. Green channel from above blended. I haven't tried mixing in the SII yet...
  4. Partied out from Saturday (my belated 40th), I decided to have a binocular tour in what were truly clear skies. Ursa Minor could be seen in its entirity, the Milky way was visible from the North of Aquila all the way to Perseus (and this is with one or two neighbour's lights still on!). It would have been nice to have a big scope session but work tomorrow and fatigue have conspired against me. Hercules: Both M13 and M92 stood out nicely. So I said goodbye to them for the year. Pegasus: Globular cluster M15 was barely inferior to M13. Aquarius: M2 was less clear but still easy enough to pick up. Vulpecula: Brocci's cluster (a.k.a. the Coathanger) lokked resplendent and M27, the Dumbbell nebula was very clear and bright. Sagitta: M71 came through nicely like a cross between a globular and an open cluster. Cygnus: M39 was lovely, M29 came through nicely, NGC 7000 (Caldwell 20) - almost certain. There seemed to be a paler patch of sky rather than any haze and I think I could detect a dark knot roughly where the gulf of Mexico should be. The sky was nowhere near good enough to see anything close to the distinctive shape but I am pretty sure I have cracked it. I also could see the Cygnus rift reasonably clearly. I can't remember noticing that from home before. Casseopeia: Fast becoming a favourite constellation. I managed to identify, M52, NGC 7789 (easiest of the new finds and quite large), NGC 129, NGC 225, NGC 457, M103 and NGC 663 (all open clusters). There were many other named parts of the constellation I absorbed but did not note. Andromeda: M31, the Andromeda galaxy was as big and bright as I have seen it. Definitely managed M32 in binoculars for the first time, possibly M110 but am far less sure: I have only managed with my scope a couple of times. Triangulum: It was not that high in the sky but M33 was no problem at all. And to think I once had problems with this one, I could look directly at it in binoculars. Perseus: NGC 869 and NGC 884, the Double cluster looked beautiful given it is nowhere its zenith yet. M34 very good too. The best bincular session for a very long time indeed. Great stuff! __________________________________________________ ______ Observing Session: Sunday 16th September 2012, 21:10 hrs to 21:55 hrs BST VLM at Zenith: 5.4 - 5.5 New - Revisited - Failed

    An early Pickering's Triangle

    Pickering’s Triangle (Seimis 3-188) It is a little early in the season to be imaging this object as it didn’t appear above my local horizon until 00:50 when I started the project earlier this month but with nights getting shorter as we approach the summer solstice, it made sense to make an early start even though it took several nights to capture the data while ducking and diving between the clouds and early morning mist! Discovery Pickering’s Triangle is part of the supernova remnant known as The Veil Nebula in Cygnus. The Veil Nebula itself was discovered by William Herschel in September, 1784 but this faint region was only later discovered photographically in 1904 by Williamina Fleming at the Harvard Observatory. The discovery was made post publication of the New General Catalogue (NGC) so it isn’t included in the catalogue. Although it wouldn’t happen today (I hope!), the custom of the time was to credit the discovery to the lead astronomer, in this case Edward Charles Pickering, the director of the observatory. Image Stats Mount: Mesu 200 Telescope: Sky-Watcher Esprit 150 Flattener: Sky-Watcher Esprit specific Camera: QSI 683 WSG-8 Filter: Astrodon 3nm Ha and 3nm OIII Subframes: 6 x 1800 sec Ha, 13 x 1800 sec OIII Integration: 9.5 hours Control: CCD Commander Capture: MaxIm DL Calibration, Stacking and Deconvolution: PixInsight Post-Processing: PhotoShop PS3 Description The nebula can be found in the north-west quadrant of the Veil Nebula near NGC 6974 and 79 (see whole Veil Nebula image below). Lying around 1,400 light years away, the beautiful filamentary elements are the expanding shock-wave from the progenitor star that went supernova here somewhere between 5,000 and 10,000 years ago. Position within the Veil Nebula Visually, the nebula responds well to the use of an OIII filter as the region is rich in OIII emissions as can be seen in the blue/green filaments in the above images. Photographically this is a wonderful object that responds well to both LRGB and narrowband imaging and the example shown here was captured using Ha and OIII filters. Although there are sulphur emissions (SII) in this region, this object responds well to my favourite imaging method of 'bi-colour’. This process uses just Ha and OIII filtration wherein the OIII data is mapped to both the ‘Green’ and ‘Blue’ channels and the Ha is mapped to the ‘Red’ channel. The greyscale images below show the individual Ha (left) and OIII (right) images used to produce this image. As you can see from the 'Stats' above, I have a whole load more Ha to collect to complete the image! The individual Ha and OIII images
  6. Faced with another good sky but not much time, I started with two open clusters in Casseopeia. Following my first sighting of NGC 7789 (Caroline's Rose) in binoculars a couple of days ago, I turned the scope on it tonight. One of the prettiest clusters around, I would say. It appeared at its best in my 15mm eyepiece (42x) where a number of individual stars were resolved and the large hazy area seemed to be mottled as though other stars were at the point of further resolution. Very nice. I moved on to the less impressive NGC 433, which appeared as a small glow around a brighter star in a v-shaped asterism between Ruchbah and Gamma Casseopeiae. Still, another one chalked off. The best was saved until last. Thanks to a post from Cotterless45, I went for the Veil nebula rather than save it for a dark sky session some unimaginable time in the future. Wow! What a stunner! First of all, I sort of stumbled across it. Not hard, given the size of the thing. As I scrolled across the sky in the right area of Cygnus, a beautiful milky crescent moved through the 25mm eyepiece field of view. The UHC filter had done its job. The crescent was of course NGC 6992 (Caldwell 33, a.k.a. the Eastern Veil). It culminated in a denser patch of nebulosity, namely NGC 6995, (the Southern Veil), slightly wider and near a pair of 8th magnitude stars. The map indicated there was more of the Eastern Veil beyond this but it seemed to fizzle out at this point for me. I recommend anyone with half decent skies and a UHC filter go for this. It is superb, like a mini-Milky Way! __________________________________________________ ______ Observing Session: Tuesday 18th September 2012, 21:10 hrs to 22:10 hrs BST VLM at Zenith: 5.3 - 5.4 New - Revisited - Failed

  8. At the end of December 2016 i captured a bit of Ha data on this target with the Polemaster and a 135mm Olympus F/3.5 lens. The image turned out quite well despite the low resolution, but i always felt something was missing - the colors... My 550D on the Explorer 200 don't get nearly wide enough FOV to match, so finally i decoded to finally give it a go with my first attempt on a mosaic. With the moon at 95% and the huge resolution difference (0.86" RGB and 5.76" Ha) i wasn't sure if i were just wasting my time, but it turned out better then expected. The RGB data is a 4 pane mosaic with a total of 46x 120 sec exposures at ISO 800. Stacked in DSS, combined with MS ICE, and processed in PS. Ha data is 35x 120 sec.

    hello all,a clear sky when i arrived home from work ,so had to whack the scope out as i heard fog was due later on. as i want outside after cooling the scope i realised the seeing wasnt great and there was some serious orange glow up to 40 degrees or so. with that in mind i stuck to a couple of constellations that were high up . cygnus m29- to get my eyes into gear i thought id visit this o/c, easy to locate. always reminds me of a space invader from the 70's video game. next up was anothr o/c ngc6910. quite a nice cluster with two prominent stars making the base or feet with lower mag stars heading off to form a point. best seen at low power x48 and 66. i tried my luck on another new object next ,ngc7027 a10.4m planetary nebula. there were two prominent stars just off deneb where i could line up the telrad with the 4* ring would put me spot on the object.and was pretty close although x48 revealed nothing just a group of field stars. had to get up to x100 to show a non stellar object with a pale blue colour,nothing to spectacular, but clear and distinct enough to crank the mag up to x170. a small shift south west to another new find ngc7063. a fairly run of the mill o/c with around ten main stars forming its framework. at this point i was looking at my pocket atlas and noticed the egg nebula. but with no details to hand and stellarium as well as "astronomical wonders" book had no details,i left it alone for now. i shall read up on that one. andromeda so over to andromeda,but tonight i wanted to view some objects in the constellation other than the m3/,32/110 trio. okay i had a very quick look to get me bearings. . i decided to try and view all the objects that are covered in " astronomical wonders" guide. ngc752. a large loose cluster spread well out ,so the 25mm e/p (x48) was all that was really usable any higher and the cluster lost itself. double star almach,57y- was amazed id not noticed this before, a stunning double with a warm yellow almach sat next to a silvery blue smaller star. a very nice find . ngc7662- the blue snowball p/n. could see its non stellar at x66 . at x170 a very mottled blue circular fuzzball. i thought this was so small and faint when i first started this hobby, now i realise its actually quite bright after getting use to brightness,magnitudes and scales of size ect. ngc891. had a half hearted attempt at this galaxy, but couldnt get anything at all. so one object from the book still to tick ! i finished tonight with jupiter again,tried to sketch it a little with not to much success, but it did help me concentrate and see details in the bands. used x171 and even x240 for a spell. x170 was best though, every now and then a few seconds of steadiness gave great views through the 7mm x-cel lx. very pleased with the range, with the 18mm and 7mm particulaly good. by now dew/fog were already showing and twas time to get the gear away.not a bad evening,and all done by ten o clock .

  17. Managed to get out of the light pollution and take this at a dark site. Really pleased with it considering the short exposure time taken. Modded Canon 1000d, 18-55 mm stock lens @ 18mm 3x 3min exposures, ISO 800, f/4.5 Custom white balance The histogram is quite far to the left on the raw files (although no data touching the far left edge), does anyone know how I would correct this next time round? From an image capture point of view? Or is this expected for this part of sky? Thanks for looking, all feedback welcomed
  18. With the waning Moon arise first after midnight, clear sky, 70% humidity, 14 degree temperature, C8 just had to get out for some action. Targets were brighter new NGCs in constellation Vulpecula and Cygnus, they were high enough to clear neighbors' roofs with good margin.SQM showed 18.5 to 18.9, quite good in my backyard. According to 666 selected DSO list, there're five(5) bright NGCs in Vulpecula besides M27, these are 6940, 6823, 6830, 6802, and Caldwell 37(6885). 6802 was the only one needed averted vision in 68x to see neblosity, doubling mag showed more faint stars, the other 4 were nice & easy target in 68x. Moving up to Cygnus, open cluster 7062 and 7086 with nice patch of faint stars, readily seen in 68x, planetary nebula 7026 could only be detected in averted vision, with UHC filter, it became much brighter and paired the neighboring star well. moving up to 130-140x, the nebulosity joined double-star look even without UHC. 7128 looked like 5 stars in a circle in 68x, with nebulosity in averted vision, moving up to 130-140x revealed more than a dozen stars there. 7044 was much more difficult, just hint of nebulosity in 68x, could be confirmed only after observing in 130-140x. IC 5146, Cocoon nebula, clearly brighter than I had anticipated, visible without filter in 50x, and UHC enhanced it even more. IC5067, Pelican nebula, absolutely nothing without filter, with UHC in 50x, a faint nebulosity shaped like a man with open arms, clearly smaller than the 1 degree size indicated. comparing to pictures later on, it dawned to me that it was only the beak I saw. Need to pay more visit here. Weather forecast looks encouraging for the weekend, fingers crossed. Clear Sky!

  21. After feeling that I had given up too early last Saturday, I was more determined to spend some time at the eyepiece. To begin with, as the sky reached astronomical darkness around 9:20pm, it was clear. I spent a little time looking for the signposts for the brightest part of the North American nebula (NGC 7000). The gulf of Mexico area is punctuated by a near perfect square of stars between Xi Cygni and Deneb. Sadly, clouds that seemed to come from nowhere began moving across Cygnus. As a result, I moved onto NGC 404, the Ghost of Mirach. The galaxy is at magnitude 10.5 but has a reasonable surface brightness. The challenge is that there is the glare of Mirach to contend with. It should make an equilateral triangle with that and another nearby 8th magnitude star. Once again, before I managed to confirm a sighting, the clouds had followed me across the sky. I moved onto Lacerta to hunt for NGC 7243 (Caldwell 16), a bright open cluster which should be more tolerant of any rogue clouds. Thankfully there was enough of a gap to confirm the cluster. Centered on a small equilateral triangle of stars, including one very close double, I managed to count between 30 and 40 members. I then tried the same with the Casseopeia open cluster NGC 7789 but had no luck as the cloud started to thicken up. .....and BBC weather said it would be clear! __________________________________________________ ______ Observing Session: Tuesday 11th September 2012, 21:20 hrs to 22:05 hrs BST VLM at Zenith: 4.9 - 5.0 New - Revisited - Failed

    IC 4996

    The ongoing deluge continues in my neck of the woods so, instead of enjoying the lack of a moon, I’ve scanned my first sketch, made this past October: Open Cluster IC 4996, in Cygnus. I’ve got a long way to go, especially with getting the scale right, but I definitely enjoy the almost Zen like state of focus that I fall into while spending 30+ minutes on one DSO. It’s also made me spend more time on each object while not sketching; its incredible the details that pop out after 15+ minutes, even in light polluted skies.
  23. I managed to have a short session in clearer skies than a couple of days ago, with a view to second attempts at some of the objects that were previously obscured by clouds. I started just before 10pm but twenty minutes of staring at the sky around NGC 7000 (the North American nebula) with and without filters produced nothing. Luckily, the Andromeda galaxy NGC 404 (the Ghost of Mirach) was visible. Not easy but with averted vision, a small circular extension to the haze of Beta Andromedae (Mirach) best seen in my 15mm eyepiece. Additionally, this is one of the easiest objects to find in the entire night sky. Even more difficult was NGC 891 (Caldwell 23), another galaxy further East in Andromeda. It is a side on galaxy but observations only revealed the feintest of small smudges with no shape discernable. I will revisit the two galaxies when they are higher in the sky, hopefully on a really transparent night. I may just be able to tease a little more out. I finished off with my most Northerly DSO find, NGC 188 (Caldwell 1) in Cepheus. Although quite easy to find, I found the open cluster a little underwhelming. I managed to count a handful of feint stars and got a hint of milky haze just to one side of a kite-shape asterism of brighter stars that surrounds the cluster. A clearer night and bigger telescope would go a long way with these three but I am happy I found them. __________________________________________________ ______ Observing Session: Thursday 13th September 2012, 21:55 hrs to 23:20hrs BST VLM at Zenith: 4.9 - 5.0 New - Revisited - Failed
