M20 Trifid Nebula in RGB

This is the Trifid Nebula, also known as Messier 20. This is true color and is such an amazing object, that I hope to image from a dark site one day. 5x120s each of RGB Total: 30 minutes of data Processed in Pixinsight Focal Length: 2350mm The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent ‘gaps’ within

Deep Sky Object Sizes in Perspective

I wondered how all the deep sky objects I’ve photographed compare in size relative to each other. So here goes something different. Each image was taken with the same focal length, 540mm at f/2.3 with a 16megapixel camera. That’s 4656X3520 pixels. I’ve reduced each one to 20% to fit them on the same 16MP canvas. In this image you’ll find: The Flame Nebula Orion Nebula (M42) 47 Tuc NGC 5128 Sculptor Galaxy Grus Quartet Horsehead Nebula Southern Whirlpool Galaxy ETA

Rosette Nebula NGC 2237

This is the Rosette Nebula. 15x60s blue 18x60s green 14x60s luminance and 2x120s luminance 20x60s red Taken with Celestron 9.25″ and Hyperstar lens @ f/2.3 and 540mm Processed in Pixinsight only Location: Tanner street observatory, Melbourne city This is by far the toughest object I’ve taken, given it’s really quite faint in comparison to other objects I’ve done. Overall I’m happy with hit. I suppose I’ll get more vivid colors once my narrowband HA filter arrives

Southern Pinwheel Galaxy

My second LRGB image and this is the Southern Pinwheel Galaxy. It was very low over the horizon on Boxing Day at about 2:30am, so it’s really noisy. Looking forward to better results as the season moves on. This is 10x60s each for RGB and 16 Minutes of luminance. Stacked and processed in PixInsight. Celestron EdgeHD and Hyperstar. ZWO 1600mm cooled to -15 degrees. Taken from my backyard in noise polluted Melbourne. #southernPinwheelGalaxy #astrophotography

Tarantula Nebula in color

This is the Tarantula Nebula, taken from my backyard on Nov 10 under heavily polluted skies. One can’t even see the LMC without aid! It’s my first attempt at deep sky imaging at full magnification of my Celestron EdgeHD9.25 and using RGB filters for the first time! This is 20x60s Red 20x60s Green 20x60s Blue Processing in Pixinsight I’m ultimately not sure what the colors are supposed to look like, but I like this take for a first attempt that
