23.01.2022 Some nice cloud colour just before sunrise at Coolum Beach. 14 panel (2 rows x 7 shots) panorama - approx 270 degrees wide. Canon 6D 16-35mm F4L lens @ 16mm
22.01.2022 Southern Cross, Pointers and Carina Nebula Complex. Canon 6D (full spectrum), 135mm mosaic, HEUIB filter.
18.01.2022 Andromeda Galaxy taken very close to the horizon from 28deg south. Canon EOS M5 + 70-200L f2.8II (at 200mm). ISO1600, 13x120s+10x40s, f3.2
17.01.2022 Infrared panoramas taken using the Kolari IR Chrome (dual band, red foliage) filter and a 630nm IR filter (no channel swap, green foliage) last weekend at Kangaroo Point, Brisbane. Canon 6D (full spectrum modified).
17.01.2022 Jupiter Rides the Scorpion Jupiter taking the reins of Scorpius via the dark nebula called 'The River'. Several red Ha emission, dark and reflection nebulae grace this region. The 'Galactic Kiwi' can be seen to the left, which also contains Jupiter (the brightest object in the scene). CentralDS 6D (full spectrum) with a Zeiss 135mm lens f2.5. HEUIB-II QRO filter. ISO3200. 8x120s+4x36s+4x11s+4x3s in a multipanel mosaic.
10.01.2022 The Scorpion's Head There is a bunch of goodies here. Some of these names already exist, but why not have a bit of fun! We have the blue horse head for a start. Rho Ophiuchi - that is just a star, right? It deserves more! What about the coloured jumping spider or a cuttlefish spraying some ink maybe? The burning ear? The night king's hand holding a red orb. Can anyone make some of those out?... CentralDS modified/cooled converted Canon 6D (full spectrum). Zeiss 135mm f2.0 @ f2.5, ISO3200, 4x3s, 4x10s, 4x36s, 8x120s multi-panel mosaic. Astrotrac See more
09.01.2022 Amazing sunset at Noosa on the first day of winter here in the southern hemisphere. Canon 6D with Sigma 14mm f1.8 at f7.1, ISO100. This is a 2 row, 10 panel panorama taken in fading light with varying exposures from 45s to 180s.
08.01.2022 The Canon R5 - WOW!!! (Utilizing video for stills / landscapes) But what does it mean for stills photographers? 8K video! Wow! There is an impressive spec list for those interested in video. But, what does full pixel readout at full frame (at 8192 4320) mean for those interested in landscape photography? Potentially a lot!!... An entire new way of using a camera for landscape photography. Maybe? If so, this would mean a revolution in the way we take photos! Photographers could even give those ND grad filters the sack (I never used them anyway). The whole DR thing is over - Canon no longer has a problem there. The 1DXIII beats the Sony A9II even at low ISO. Canon landscapers just long for a high res, with new sensor tech cam - and the R5 is it! 45MP of brutal grunt. The RAW video potential! Could this correlate to unlimited DR for landscape photographers? Anyone thought of using video to capture a landscape image? This could render the dynamic range argument useless. A potential for 16 stops+ of DR. There is a caveat and a solution. Yes, you could take a single frame (limited DR) or a 3 shot bracket. The later has problems that I deal with all the time This could be taken a step further using amazing video without the ugly side effects of bracketing 3+ shots with a moving scene. I am talking about dialling in the highlights with a stop short of clipping and capturing every single photon in the shadows (not quite, but you get my drift). The longer the vid clip, the higher the DR and the deeper the apparent ND filter and the better the shadow details. A load of potential! Using a neutral style profile, take a short clip at, say 4 seconds, at what ISO demands on a particular scene. Leave a stop for highlights clipping. 30fps*4 = 120 frames. Remember that signal to noise ratio = signal / sqrt (noise / number of frames). The more frames - the lower the noise and the more precise the signal. All those frames have been taken at 12 bit. Stack all those frames while expanding to a 16 or 32 bit tiff/fits file. This would also work as an artificial ND filter where 1/30s or 1/24s for as long as you want and take it past 15 stops of ND if you like. What if you want a people free / unwanted moving objects frame median stack. Bright cloud trails maximum stack. Caveat - Flaws in the sensor readout the last common denominator. Solution A bit like what astro-photographers do. This problem could be addressed by taking video in the dark (lens cap on) to create a bias file. This bias file should be made at a similar temperature to conditions on site. This file can then be applied to all files taken on site. What do you think?
07.01.2022 Shelf cloud of the storm that hit the Sunshine Coast early this afternoon. Large hail was reported from Mooloolah Valley to Caloundra causing damage to cars and homes. This multi panel panorama was taken from Point Arkwright.
07.01.2022 Very stoked, proud and humbled to score a win in the wide field division in the David Malin Awards! Some amazing photos entered and congratulations to the overall winner Mark Polsen. Here is the wide field shot of the Gum Nebula. A tough one because it spans about 30 degrees across the sky. Image details as follows: Canon 6D (full spectrum modified) with a 135mm lens at f2.5, ISO3200Multi panel mosaic combining data from two filter arrangements. 4x3s, 4x11s, 4x38s, 4x120s with IDAS HEUIBII filter, plus a diffuser filter to reveal star colour and intensity (50 panels). 4x60s, 8x180s with IDAS NB1 (dual narrow band Ha & OIII) filter to reveal nebulae (25 panels). Tracking via an AstroTrac TT320X-AG
06.01.2022 Carina Nebula Like the Orion Nebula, this nebula has an overwhelming Ha (hydrogen alpha - pink/red) component to the point that the OIII (oxygen - cyan/green) is lost when imaging using a full spectrum camera. In an effort to reveal the OIII (and subdue the Ha), my old 2013 Canon 6D was used along with an Astronomik CLS-CCD dual band filter. Star colours aren't good, but I am happy with nebula colours that normally cannot be separated using a full spectrum camera. Also happy ...to score this using a 200mm lens on a Vixen Polarie using a dodgy counterweight system :) Canon 6D (unmodified), EF 70-200 f2.8LII at 200mm wide open at f2.8, ISO3200, 4x3s, 4x9s, 8x30s, 8x90s. Tracked using a Vixen Polarie See more
04.01.2022 Comet Swan C/2020 F8 Taken 2nd May using a Canon EOS M5 + 70-200L f2.8II (at 200mm). ISO1600, 7x120s+6x40s, f3.2. I would have liked a load more shots at 120s, but had some technical issues on site, so it is a bit noisy.
01.01.2022 A wide view of the South Celestial Pole showing some dust and some galactic features surrounding the Magellanic Clouds. Note the irregular spiral structure of the LMC. Canon 6D (CentralDS modified & cooled), Sigma 50mm, 8x120s. 4x30s, 4x11s & 4x3s, ISO3200. Multi-panel mosaic.
