25.01.2022 Work in progress. NGC 3576, the Statue of Liberty nebula in Carina. About 8 hours of Hydrogen alpha data. Will hopefully add in some Oxygen and Sulphur data later this week.

25.01.2022 NGC 3576 in Hubble Space Telescope Palette. Hydrogen to Green, Oxygen to Blue and Sulphur to Red. Then fiddled about with in Photoshop to make it look nice. Larger version at https://flic.kr/p/DNYLvL

23.01.2022 There are two bright(ish) comets in the night sky at the moment. This one is very much in the southern skies. As a first time visitor to the inner solar system the comet is producing quite a show on approach to the sun. After perihelion, the comet will switch to the northern hemisphere skies and may put on quite a show. But first time comets are notoriously unpredictable. As the weather improves in Melbourne I should be able to get more pictures of the approach to the sun. Larger image at http://astrob.in/full/202414/0/ Share and Enjoy

20.01.2022 Gum 15, another processing challenge. the luminance channel, taken using the hydrogen alpha emissions washes out the colour. Much photoshopping later, most of it is back with most of the detail from the luminance intact. A very dim target. Share and Enjoy

20.01.2022 Well, I'm a bit nervous, but I'm about to be exhibited. Ballarat International Foto Biennale ASV Astrophotography Exhibition - "Wonders of the Universe Exposed". The Ballarat International Foto Biennale (BIFB) is a month-long festival of contemporary Australian and international photography. Held every two years in the beautiful and historic city of Ballarat, the BIFB presents two major exhibition programs. The BIFB Core Program is a curated exhibition of 20 leading photogr...aphic artists, while the BIFB Fringe Program is an open-entry presentation by more than 200 artists. Our exhibitions are staged in more than 80 venues across Ballarat, including historic buildings, cafes, galleries, and public spaces. So, if you're near Ballarat when this is open, drop into the Gold Museum opposite Sovereign Hill. http://ballaratfoto.org for more info. As this is my first experience of an exhibition, I hope it all goes well, there are 20 or so co-exhibitors, with some magnificent astrophotos, I'm sure you'll enjoy it.

16.01.2022 I managed to add some RGB data to the Ha data I acquired for the narrowband version of this. I had to invent a new way to make a master luminance as the stars were very much smaller in the NB data, so ended up with dark halos around them when the colour data was added. Seems to have worked OK, but I may still change a few of the blending options in PS. I have processed the image to accentuate the different red colours in the image, hope you like.

11.01.2022 Should anyone wish to see the exhibition... To avoid paying the $12.50 admission fee, please collect an official BIFB program from the Mining Exchange, 12 Lydiard St North, Ballarat and present it at the Gold Museum for free entry. So get a programme and you'll get free entry, they ask for a gold coin donation for the programme.... Also, the photos will be available for purchase from the gallery shop, orders will be taken for both mounted and unmounted prints. The prices aren't set firmly yet, if any of mine sell I'll be donating profit to my shitbox rally NZ team... https://shitboxrallynz-2016.everydayhero.com//kiwi-air-for

10.01.2022 Exhibition coming together...

08.01.2022 Hi All, Here's the Puppis A supernova remnant in Ha/OIII. I used the Ha data for the red channel, and the OIII data for the green and blue, I then combined all the data to make a master luminance frame and combined it all in photoshop. There is some short RGB data for the stars as well.... A subject with a large dynamic range, some stuff reasonably bright but much more which is quite dim. The blue gradient appear to be real as it is on all the subs. The red nebulosity in the background is one of the Gum nebulae. A really fascinating target, I hope you like my rendition. Share and Enjoy.

04.01.2022 This image was taken over two nights on the 7th and 8th of February 2016. It is part of the Eta Carina Nebula entered around the Wolf-Rayet star WR 22 (the bright one in the middle), off to the right you can see the Eta Carina, a prime candidate for going supernova, it may have already done so, but it's 7500 light years away. Mapped in Hubble space telescope colours, with sulphur mapped to red, hydrogen to green and oxygen to blue.

02.01.2022 Well, it's been a long time between drinks. My Camera broke again and had to be sent to the US for repair. Since getting it back and testing there have been limited nights for imaging. Here's M42, the Great Orion Nebula, this one is very bright so the challenge is to reveal the outer parts of the nebula without overdoing the more central parts. Then combining in the colour is also difficult as the intensity of the luminance data tends to wash out the colours. So an "easy" ...target, so called because it's bright, turns into a difficult target to get a nice picture. This one is a combination of 60, 120, 300 and 600 second exposures for the Hydrogen alpha, layered in in Photoshop to make the luminance image, with colour data at two exposures as well. Share and enjoy!

02.01.2022 A new revision of the Cat's paw nebula photo. After some suggestions I thought I could make some improvement. I had to tone down the sharpening, which I didn't want to do, but after some persuasion acceded. Full resolution here http://astrob.in/full/207721/B/

01.01.2022 Due to the rather poor weather here over the past few months, clear skies have been at a premium. This image is the result of about 9 hours total exposure, spread over three nights in August and September. This is NGC 6334, or The Cat's Paw Nebula. From Wikipedia...... NGC 6334 (also known as the Cat's Paw Nebula, Bear Claw Nebula and Gum 64) is an emission nebula located in the constellation Scorpius. It was discovered by astronomer John Herschel in 1837, who observed it from the Cape of Good Hope in South Africa. Larger version at http://astrob.in/full/207721/0/ Share and Enjoy!
