25.01.2022 America the Bold. NGC 3576 Statue of Liberty Nebula. Taken with just 1.5h of light in our primary location. Want to see more like this? Consider supporting us on Patreon! Head to Patreon.com/lonosham to find out more.

22.01.2022 A clear evening last night saw more time on NGC 6188. Added to previous sessions, and processed in PixInsight, sees great detail coming out!

20.01.2022 Taken over multiple sessions, here is the Carina Nebula from 5 hours(!) of imaging, using the Askar FRA 400/5.6 and a Fujifilm X-Pro1 camera. Love the natural colour!

19.01.2022 After 2 months of nearly constant cloud, we will take any time we can get! Even when evaluating a 0.75x focal reducer (unsuccessfully), get as much data as you can! With an additional 25 minutes of hydrogen alpha and oxygen-3, NGC 2539 Thor's Helmet is starting to really pop!

17.01.2022 Two sessions on the same target have prevented the acquisition of Oiii data, but The Cat's Paw Nebula (NGC 6334) is still beautiful as an HOO image! Part of a star-forming region, new wonders will be visible in the (far) future!

17.01.2022 Tarantula Nebula just got a whole lot closer!

15.01.2022 Clear conditions overnight in Sydney allowed for some spectacular images. Here’s the Cat’s Paw Nebula, 24x60s Ha, 15x60s Si ii, 15x60s Oiii. More imaging time on silicon and oxygen was planned, however a meridian flip issue cut short the imaging on this target.

15.01.2022 Last night had perfect conditions, so founding member Kevin went out of Sydney to avoid the light pollution with his moveable setup, and captured this amazing shot. APOD, anyone? Behold, IC 434 The Horsehead Nebula, and NGC 2024 The Flame Nebula! This shot is available for print - or if you'd like your own copy of amazing shots sent to you when they are created, consider becoming a Patreon supporter! https://www.patreon.com/lonosham

13.01.2022 Australia is moving in to "Orion Season" so here is one night's imaging on this stunning target. Designated as M42 and NGC1976, The Orion Nebula is visible to the naked eye in dark enough skies, and one of the most popular astrophotography targets due to its size, brightness, and complex nature. This shot is composed of just 8x120" Ha, 5x120" Oiii, and a paltry 3x120" of Sii, rendered in Hubble Palette HSO composition. Shot with a ZWO ASI 1600MM camera through an Askar FRA 400/5.6 quintuplet telescope, on an HEQ5 Pro tracking mount.

12.01.2022 The observatory had its first full night of imaging in 2021, revisiting NGC 2736 The Pencil Nebula. 31x 300 in Ha, Oiii and Sii, giving just under 8 hours total integration time.

12.01.2022 NGC 253 The Sculptor Galaxy. Big things can be tiny, and tiny things can capture big things! Despite not being the best equipment for galaxies, here's a great shot using a telescope with just 400mm of focal length at one of our remote locations to mitigate some of Sydney's light pollution on the evening of October 20, 2020 (2020-10-20). 3x20 minute plus 1x10 minute shots per channel, composed of 3.5nm Hydrogen Alpha, Green, and Blue visual filters combined using GHaGB palette.... As an intermediate spiral galaxy undergoing starburst formation, creating stars at a significantly greater rate than the average.

11.01.2022 The misty magesty of the Eagle Nebula. Catalogued as Messier 16 (M16) and NCG 6188, this region rich in Hydrogen-alpha also includes the famous Pillars of Creation that were captured in exquisite detail by the Hubble Telescope. This shot, taken in a single night at Lonosham Observatory, shows what can be done by almost anyone, with consumer equipment!

11.01.2022 A sparklingly clear and crisp evening in Sydney allowed for some brilliant results! The Prawn Nebula captured on 2020-08-05, from a very limited number of exposures! 3x300s Ha, 6x300s Sii, 6x300s Oiii

10.01.2022 What is your favourite all-in-one tool like Sequence Generator Pro, N.I.N.A., Voyager, Astro Photography Tool, or evening SharpCap? Enquiring minds want to know!

10.01.2022 From the archives: The Tarantula Nebula (catalogued as 30 Doradus) is a region of ionised hydrogen gas in the Large Magellanic Cloud. A stunningly complex part of the sky, there are dozens of nebulae in this area with 30 Dor one of the most recognisable. Taken with ZWO ASI 1600MM monochrome camera with Hydrogen alpha, Oxygen iii and Sulphur ii filters.

10.01.2022 Behold, NGC 2020! Whilst the year may have been a proverbial dumpster fire, the namesake nebula is an exercise is stunning contrast. The blues come from the rich oxygen regions, whilst the red and yellows from the larger hydrogen patches. With just one clear night forecast for the next two weeks, every second of the clear conditions last night became precious. A Windows update automatically rebooting the command and control PC at 1:30 and losing 3 potential hours of shooting was NOT welcome! With skies darkening early, it was perfect timing to set up after the gym. 30x300 Ha, 16x300 Oiii and Sii.

08.01.2022 With our normal remote location undergoing maintenance, a backup location was sourced. Some limitations with visibility to the horizon allowed us to choose our favourite high-sky target, The Helix Nebula! Integration time: 3 hours (18x300" Ha and 18x300" Oiii) Telescope: Askar FRA 400/5.6 quintuplet Camera: ZWO ASI 1600MM... Filters: Antlia 3.5nm Mount: SkyWatcher HEQ5 Pro See more

07.01.2022 The Eagle Nebula, catalogued as Messier 16 and NGC 6611, is a region of new star formation 5700 light years away. In popular history, it was made famous by the Hubble Space Telescope for its capture of The Pillars of Creation in the centre of the nebula. This image is based on data collected on two evenings in August and September 2020 and totaling 10h 45m integration time.

06.01.2022 After two months of nearly constant cloud, it was good to get a break in the weather for a quick session! Behold, NGC 2467 Skull and Crossbones Nebula. Limited frames on this target means watch this space for improvements over the next few months!

06.01.2022 One and done! NGC 7293, the Helix Nebula, is a ‘close’ 650 light years away, and is often called The Eye of G-d. To get enough light for a target in a single night is what we aim for here at Lonosham Observatory, and last night Sydney’s Lower North Shore had perfect conditions for imaging.... Specifications: HOO palette: 9x600 Ha, 18x600 Oiii Askar FRA 400/5.6 telescope ZWO ASI 1600MM camera Antlia 3.5nm filters

05.01.2022 With the horrid weather settling in this weekend over Sydney, perhaps now is the time to update your darks library! Temperature of the sensor, exposure times, and gain/ISO should be the same as your light frames, and you should take 20 or more of them. If you’re lucky enough to be cooling your camera, you can probably set and forget but a fridge and an intervalometer (or old school trigger release cable!) can be used for other cameras like DSLRs....

04.01.2022 With awful weather taking a break, some time spent on a target in the Large Magellanic Cloud - NGC 1763. A few precious hours of data, soon to be combined with a previous session. . patreon.com/lonosham . 12x300 Ha and Oiii subs... . GSO 8 Ritchey-Chretien telescope, ZWO ASI 1600MM camera, Antlia 3.5nm filters, ZWO ASI 174MM off-axis guiding, SkyWatcher HEQ5 Pro tracking mount. See more

03.01.2022 Lonosham Observatpry donated three pieces to a Children’s Cancer Institute charity art fundraiser, and they sold for $1000, the highest sale of the night! If you’d like your own prints, please reach out to us for image and printing options!
