  1. Took this M104 aka the Sombrero Galaxy during my lest year visit to Namibia (April 2017). M104 is quite a small object for an F3.6 telescope but since it is very difficult to photo this object from my country I decided to take some photos. Hope you like it Photo details: 6 x 10Min Luminance in BIN1 = 1 Hour 25Min for each RGB in BIN2 = 75Min Total Expo: 2:15 Hours Hardware used: Telescope: ASA 12'' F3.6 Astrograph Mount: ASA DDM85 Mount Camera: FLI8300 with Astrodon filters You can also check my other versions of this Galaxy in my Flickr page: https://www.flickr.com/photos/101543943@N04/ Thanks for watching, Haim Huli

  3. Registration done in medium conditions, so I had to extract too much of the processing to be able to bring details, which I do not like to do. I always prefer when the image is already good in the stacking done with sharpened AS! 2.

  4. Greeting everyone! I have been doing a lot of reprocessing with PixInsight as I just installed it a month ago. Im really starting to get the hang of it, and I must admit.. The learning curve isn't as steep as I had originally expected. My biggest nemesis is a noisy background and small stars. I'm starting to get the hang of star masks but maintaining low background noise through processing is definitely more difficult. Anyways, this is repro of Messier 45. This image was taken with a 102mm APO by William Optics, an ATIK 414ex Mono, and an Orion Atlas. I gathered just under 2 hours of data using Astrodon RGB filters under bortle 4 skies using 300s-600s exposures. Hope you all enjoy and clear skies!

  6. A short break from the relentless poor weather this year allowed our builder member Phil to finish the walls of our proposed remote telescope facility They will be rendered in due course. I've spent a couple of days digging out flat areas for the 4 pillars that will support the rails that will carry the horizontally biparting doors. The instrumentation is likely to be a 12" SCT, wide field refractor and an all sky camera. The mount, initially will be a EQ6pro. The project is intended to provide remote members with the opportunity to image from home. Don't hold your breath though as it is a fairly long term undertaking which will evolve stage by stage, updates will be forthcoming as and when appropriate.

  7. Hi all, It's been a very informative (and frustrating!) first season of imaging with an apochromat and specialised astrophotography camera. Having acquired an ASI 1600MM-C in early 2017 and my GT81 in August, I've had my fair share of gremlins, but managed to pull out a few keepers. Processing has always been a bit of a mystery to me, but I'm finally starting to get to grips with Pixinsight and APP; APP in particular has been a lifesaver for integration and LP removal. I thought I'd make a collage to chart my progress so far. Also includes a couple of widefield milky way shots and a lunar image for good measure. Counting down the days until next winter so I can get back to the GT81 and give my new Avalon a proper run for its money! I've recently purchased an Altair Astro RC6 to give me a bit more reach for the upcoming galaxy season, so looking forward to that. I considered an Edge HD 8” so I could also do some planetary work, but even the used prices were prohibitive so I decided to stick with an RC6. It’s nice and light and hopefully the FL won’t be too challenging, plus I can use my old Lakeside focuser motor on it. Happy to provide equipment details if anyone would like them. Cheers!

  8. This very nice Arp galaxy (NGC 0104) in Pisces is a real beauty! I tried it last night and I couldn't be more enthousiastic! You do need a special filter to bring out the details but WOW... Even under a full moon, this one blew my socks off! Give it a try tonight! You won't be disappointed

  12. As well as the fun and games in my other posts this evening I did capture some proper data as well. This is 25% of 300 frames captured with the Mak and the D3200. Pipp>AS!3>IMPPG>Photoshop. The moon was extremely low but still gave me some reasonable detail. Mono RGB Saturation boosted beyond sensible limits

  14. I've impressed myself here. Or rather the gadgets have impressed me. I've used an iPhone app called Procam for afocal captures before but with the iPhone X having a 'zoom' lens and the app having pretty good manual controls, and a pseudo image stabilisation function when you use digital zoom I thought I'd have a go at the Full(ish) Moon with the phone for fun. No telescope involved. Here's the result. Captured at ISO 15, 1/350s, manual focus with focus peaking to assist. Handheld resting on the garden wall for support. Then a little sharpening in Photoshop Express on the phone.

  15. This is a mosaic from one camera and two telescopes on three occations. Background is done with a 700mm F6.5 apo but for the galaxies I used my Meade LX200-ACF plus 0.78x reducer. Each one of those got 26x15 min @iso200 with a modded Nikon D7000 and CLS filter. Mount is HEQ5 Pro, guided with a standalone NexGuider. Captured with DslrDashboard on Android tablet. No darks, flats or bias used. Processing with Registar, PS and Topaz Suite. Ragnar

  16. I get up a couple of hours before dawn this morning and am greeted with a beautiful pairing of Saturn and Mars. Saturn looks beautiful, tilted perfectly in our direction, a bright peach orb sporting good detail including the Cassini division. Mars is definitely getting bigger and brighter, and is decidedly more reddish than Saturn. I can see a little detail now. I excitedly try out my Mars filter but don't see significantly much more detail (in fact, the overall tint is actually a bit distracting); maybe, it will work better as Mars gets closer). Jupiter, a little farther west, is an awesome, large, bright orb with striking belts, and the moons have a curious question mark-like configuration this morning. The regal Blue Moon is on its way to set, but I don't risk my "dawn" vision looking at it through the eyepiece. The air is pleasantly cool, nowhere near as chilly as some previous mornings (the weather here can't make up its mind if it's winter or spring). A little humid, so I pull out the dew shield. Well, what do you know, there's a developing high cloud to the west, threatening to interfere, lol (fortunately, it doesn't). I really want to see Mars and M22 together, less than a half degree apart, so that means I can see them in a telescopic view! Time to image! I set up the camera on the 127mm Mak and take several shots, this one being my favorite: And here is another pic taken several minutes earlier: Reggie

  17. Here is a image based on more Ha data from the last nights but here mainly collected by my Canon 300mm f/4 lens (38 x 10-12 min with an unmodded Canon 60D ISO1600) with Ha data from my 5" refractor (sitting side by side, 18 x 25 min with a Canon 60Da ISO1600) added centrally. The RGB also comes from the Canon lens and a 60Da but collected in October (96 x 3 min ISO1600). C & S most welcome Cheers Göran EDIT: I added the Ha data as a B/W image

  19. A new optically perfect poly plastic has produced prototypes of huge mirrors for amateur observers. Formed into prisms , then aligned onto a focal point , light can be picked up at the focuser. The primary mirror may take the shape of a traditional disc, but there are trials of a thin straight sectional secondary which would allow a cheap dream lightweight 30" aperture to be easily transported . Here's a bit of the base section , Hopefully we'll be seeing these in action in a year's time, Old Nick.

  21. Wikipedia's Bortle Scale page says that a Full Moon in a dark location gives you an "effective Bortle number" of around 7, except the sky will be blue rather than greyish-orange. Well, I am for this fortnight at quite a dark location (21.8) a couple of miles from Baltimore in SW Ireland, and last night (31st March 18, Easter Saturday) was a clear-ish night with a high Full Moon. You can see from these images, taken with Daylight white balance on a Canon EOS6D + Samyang 24/1.4, that the sky at 2140 was very blue! Exposure in each case was 1 second, ISO 1600, f/1.4 (by contrast, a picture I took of a similar scene in winter 2016 from the same place with no Moon required 45 seconds with the same set-up on otherwise identimcal settings!). Winter Triangle, Orion, Hyades and Pleiades, looking West towards Baltimore:

  24. This is a collaboration between me and Peter Rosén where my part mainly was the photon collection with my old trusty C14 and Peter took care of the processing. M82 has a large outflow of hydrogen perpendicular to the galaxy. Part of the hydrogen probably comes from an earlier close encounter with its neighbor M82 and it has triggered a massive star formation and also numerous supernova explosions. In our galaxy it can be lifetimes between supernova explosions but in the area from where the gas emanates in M82, it happens about once a decade according to the Wiki and these explosions blow the gas outwards as can be seen in images of M82. Total exposure time a little more than 12h and about 2/3s of this was with the Ha filter. /Lars

  29. Louise, this bought back some memories of me a teenager, rummaging through the military surplus and electronics stores in Londons Tottenham Court Road after school in the 1970's for a photomultiplier tube to complete an electronics magazine project "Build your own Geiger counter", can't recall which magazine though. It worked too, and despite being bitten by the PM tube's HT a couple of time during the build it provided endless hours of fun, particularly for family, neighbours and friends who thought my brother and I were quite mad testing everything we could find for radioactivity. The luminous paint on the face of old Timex clocks from Glasgow? seemed particularly active and my father had some masonry drill bits (cobalt?) that gave quite a high reading too. William.

  30. Me too. 6ft 5ins and a steadily worsening back injury. For me the FC-100 is in a class of its own - a sub-3kg 4 inch 'scope with excellent optics which sits happily on a camera tripod and is airline cabin portable. The only competition I guess would be one of the Borgs. I just consider myself lucky to have such an option because even the C8 was getting too much for my back.

  33. very cloudy here and the gaps had thin cloud in them but after seeing a new small AR through the ep first thing, I relentlessly tracked them down . some nice proms on show if you get the chance, a lovely loop on the off going limb and smaller ones around the disc. sorry my AR shot isn't very good the proms show up better through the cloud but in the vis I could see 3 small spots/pores in the middle of the snakey stuff. kit starwave 102, quark, asi120mc. hope you all have some clear, thanks for looking. charl. prom off going limb mid. proms off going limb upper. prom oncoming limb upper. prom oncoming limb lower. new action, its only small but ill take it.

  35. Cheers! The step from 10" to 15" for me was well worth it. My 10" 250px is a great scope, but the extra aperture is just great on globs, planetary nebs, teasing out a little more galaxy detail, etc etc. The extra light is very welcome for use with an O-III, along with in general the increased image scale at similar apparent brightness. A key thing is just how smooth it moves: this makes it a joy to use for high powered planetary viewing. Again the extra light is a real benefit I find - lovely bright, colourful images. I know an f4.4 dob is not regarded as a planetary scope, but it can deliver great views imho, when conditions are right. I even use it unfiltered on the moon too

  43. Maybe, but the Borg 125 I owned when I lived in the Far East was not that good visually (OK, I might be a bit picky!). I had much better images with my FS102 - which also has much better construction quality. Hence I stuck with the Tak. The Borgs do have the advantage of breaking down into smaller parts, though.

  45. Get strong magnet, put in thick sock, tie a rope, go to river with rocky bottom. I drag a powerful magnet behind my canoe, find lots of rocks with a charge, trash and a car that stopped me in my tracks. Yet to find a meteorite but they are everywhere, found some cool junk and a prehistoric artifact that dated nearly 4000 BCE.

  46. as the weather is bad again.. and again... I've reprocessed M51 taken last year (sorry for that...) This time I've done it with "Siril" (I've just started to use this soft instead of DSS, and I think the colors are better)

  47. Hello all. I'm back in DSO imaging after a cloudy and rainny winter Here are some images of this month made in south of France, always with my 16'' altaz dob by SkyVision and the sony A7S. The results are not as good as I would like but I'm still learning, and have not enough time to practise. Try to do better next time.

  48. Hi all I just took possession of my biggest scope ever, a 20" Dob. We had to cut off the front of the large shed and fit hinges so the shed now has a double door. Then we fitted permanent planks inside and a moveable ramp on the outside. There's a large mirror at the back so you can check the wheels Stay on the ramp during roll out. Short video of its inaugural roll out here! Iain http://fouragesofsand.blogspot.co.uk/2018/02/the-half-metre-dobsonian-telescope-see.html

  49. It´s been a while and the season is soon over but last weekend I pulled myself together for some astroscaping After 4 hours in -12 degrees Celsius I couldn´t feel my toes Hurt like crazy when I got them warmed up again. This is a composite image, since I used tracking. Sky: 120 seconds at ISO 1600. Foreground: 60 seconds at ISO 3200. Samyang 24/1.4 @f/2.8 Canon EOS 6D AstroTrac TT320X-AG Hope you like it!
