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

Saturn in full colour

  Tonight’s conditions were supposed to be good according to ScopeNights yesterday, but deteriorated throughout the day. I managed to get a quick RGB of Saturn in after some visual of Venus and Jupiter’s conjunction. Conditions must have been reasonable, given the detail I got. This is 1000 frames each of RGB (thanks +Kevin Franklin for the suggestion to increase the frames), stacked in AutoStakkert 2, and then processed in Photoshop. +Dylan O’Donnell you’ll enjoy that the colours are closer

Saturn Take 3

Tonight’s been the first in over 3 weeks where we’ve not had a cloud in the sky! Despite near freezing temperatures it was a good night. I tried my 3rd attempt at deep space stuff, and failed miserably again, but given conditions were reasonable I got a couple of nice shots of Saturn. 2,000 frames, top 20% stacked in AutoStakkert2, color combined in Photoshop, no further processing. Taken on a Celestron EdgeHD 9.25″ using a ZWO 120mm on an NEQ6
