Today I'm starting a #thread compiling the best astrophotography I've got (so far) during my career. This will compile images obtained with both amateur and professional telescopes, sometimes using archive data too. All will be included in my #Flickr album https://www.flickr.com/photos/angelrls/albums/72157716512276437
I'm starting with this crazy image of the Lagoon Nebula I got using the 2.5m INT @INGLaPalma when I was a PhD student at @IAC_Astrofisica. This is the 2016 version, the original one was obtained in *2005*, when colour photos using Hα+[OIII]+[SII] were rare https://www.flickr.com/photos/angelrls/27545798056
It's nice to compare that image of the Lagoon Nebula with this one I got 2 months ago using my small 80mm refractor telescope and @zwoasi camera from my backyard, 15km from Sydney's city centre. This is just *a test* of what I hope to get soon. Red is Hα https://www.flickr.com/photos/angelrls/50262702166
I'm also using this #thread for updating my #Flickr. I just uploaded this wide field view around the Lagoon and the Trifid Nebulae. 15 x 5 min exposures at 200mm f/2.8 CANON 5D Mark III on 19 Sep 2017. Piggyback, no autoguiding, full processed with PS https://www.flickr.com/photos/angelrls/50499666133
You've probably seen many images of the Trifid Nebula. This is the updated color image I got in 2005 combining Hα (green) + [O III] (blue) + [S II] (red) data obtained using the WFC @ 2.5m INT @INGLaPalma while I was a PhD student at @IAC_Astrofisica https://www.flickr.com/photos/angelrls/50503389988
Again, the view of the Trifid Nebula using an amateur telescope is quite different to that. Last June I got this colour image of M 20 using my Skywatcher BD80 + @zwoasi 178MC + @Optolong_filter L-Pro filter from my backyard, 15 km from Sydney's city centre https://www.flickr.com/photos/angelrls/50015249027
I've taken *tens of thousands* of astro images with DSLR, many for time-lapses while working as support astronomer at the Anglo-Australian Telescope (AAT). This is a single 20s shot showing the Emu over the AAT. The dome was briefly illuminated by a car https://www.flickr.com/photos/angelrls/28379055959
The Southern Cross, Carina, & the Pointers (α and β Centauri) from Siding Spring Observatory. Stacking 20 x 15s frames with CANON Mark III, 14mm lens, f/2.8, on a tripod. Some clouds around, making the brightest stars much bigger! α Cen is a double star https://www.flickr.com/photos/angelrls/50513699662
As I've been quite busy observing at the AAT while supervising two amazing students during the weekend, I've not continued this #thread so here I go again: I took this photo of the Crescent Moon and the AAT inside the dome the 2nd March 2017, at 8pm AEST https://www.flickr.com/photos/angelrls/33076675731
Following the announcement of the (re-)discovery of water on the Moon, I'm including in my #Flickr album an image showing 8 of the (many) shots of the #Moon my son and me took last year. Full details, as always, in the description below. https://www.flickr.com/photos/angelrls/50535990702
