    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

    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.

    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!

    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.

    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!

    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

    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

    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.

    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

    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

    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

    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.

    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:

    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

    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.

    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.

    At 51.5 degrees North, Sherkin Island is the second most Southerly point in Ireland. At this latitude the Milky Way does not get very high in the sky. The forecast was set to clear at about 3am, and thankfully it did about 03:40, leaving me with 50 minutes to get the shoots. I had lugged 15Kg of gear a few kilometres down to the Horseshoe Cove to set up. This is 6 panes, each 25s ISO 10,000, at f/2.8 with a Canon 5D and 14mm lens. I stitched the pic in PTGui. Processed in LR and PS. The light on the horizon to the left is from the same town of Baltimore. While this was back on the mainland and to the North East, it features prominently in the image. Yet the view to the South and West are as dark as I have ever seen. I have processed this heavily, but being a 6 pane image, you can push it quite a bit given the resolution. Just above the house to the right is Jupiter, with Mars and Saturn near the horizon in Sagittarius. Tom.

    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.

    The 70-200mm L IS II is an excellent lens for widefield, you should be able to use it wide open. Paired with the 6D will make a very nice widefield setup.

    There are so many complicated, and sequential operations that are required to work flawlessly for this huge instrument to ever become operational, one has to wonder if the story will have a happy ending. I'm not a Doubting Thomas, but Sod's Law will be lurking. Be one Hell of a Challenge getting a repair mission out there. Might be prudent to unfold the thing in low earth orbit, then if all's well, tow it out to where it needs to be. Not sure if that is feasable.

    I'm not sure of the speed you need your mount to be capable of to track the ISS, but 10°/sec will be fast enough. I say this because of the 10 Micron mounts, which can pinpoint and track the ISS very accurately, they have a max speed of 10°/s. Here's a short vid I took, focal length around 1.1m here, but have done it at 2.5m too. The key to accuracy is getting the latest TLE data for the ISS. Cheers Tim

    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.

    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

    Hello all. I love this thread. Gives me hope after being told of all the other avenues I've asked questions on to not bother trying if I don't have eq equip. So this is my first multiple image attempt. I piggy backed my Nikon d5300 with the kit 55mm to 200mm lense @200 on my 9.25 sct on the evo mount. I had about 20 minutes to get anything due to weather. This is about 29 20 second exposures at 1600 iso. I managed a few bias. No flats or darks. Messed about on the trial pixinsight and stacked on dss. Pixinsight even though expensive when I buy is the only one I could get my head around. I tried star tools but my pc isn't up to scratch and a few others that I had no joy with. Looking forward to trying properly when the weather permits with my 102mm refractor on the same mount.
