I shot sets of constellation images, among them this one framing Queen Cassiopeia and King Cepheus.Ĭassiopeia is the well-known “W” pattern at lower left. This is a photo from last night’s shoot, taken on a very clear autumn night with the Milky Way prominent across the sky. I shot this from the backyard of my New Mexico winter home.Ĭassiopeia and Cepheus reign over the autumn sky amid the Milky Way. They are artificial (refractors don’t produce spikes on stars) but they add a photogenic touch to a rich starfield. I used one of Noel Carboni’s “Astronomy Tools” Photoshop actions to add the “diffraction spikes” on the stars. Back-designed) 92mm apo refractor, working at a fast f/4.4 using a Borg 0.85x field flattener and focal reducer. I was shooting through one of my favourite telescopes for deep-sky photography, the TMB (Thomas M.
QUEEN CASSIOPEIA ISO
The image is a stack of 20 six-minute exposures, taken with a filter-modified Canon 5D Mark II at ISO 800. On northern autumn nights this region of the sky and Milky Way lies high overhead. The Soul Nebula lies 6,500 light years away in the Perseus Arm, the next spiral arm out from ours in the Milky Way. I like this image for its variety of subtle colours, not only the reds and magentas in the bright nebula, but also in the dark sky around it from dim dust adding faint yellows, browns and even a touch of green. Here I’m framing just the Soul, taking in some of the faint nebulosity to the left of the main nebula, including a tiny object called IC 289, a star-like planetary nebula at upper left. Both shine on the eastern side of Cassiopeia the Queen. It is often depicted framed with a companion nebula just “off camera” here to the right, called the Heart Nebula. I shot this image last night, capturing an object prosaically known as IC 1848, but more popularly called the Soul Nebula. The Soul Nebula glows from within the constellation of Cassiopeia the Queen. It really brings out the diversity in star colours, and sky colours, from the dusty orange-brown region at left, to the inky dark dustless region at far right. In all, it’s the best image I’ve taken of this much-shot area of the sky. All processing was in Photoshop, including the mosaic assembly. I used the filter-modified Canon 5D MkII and shot through the TMB 92mm apo refractor at f/4.4. Plus I shot two others to span the region of the Milky Way that is about seven degrees long, a binocular field.Įach of the 3 segments is a stack of 12 frames, with each frame a 6-minute exposure. I shot the frames for this 3-segment mosaic over two nights, with one segment taken from the frames that made up the previous post.
QUEEN CASSIOPEIA PATCH
The separate patch of nebulosity at upper right is NGC 896. Amid the swirls of nebulosity are numerous clusters of stars, such as NGC 1027 just above centre. They are otherwise respectively called IC 1805 and IC 1848. Now, here is the matching Heart Nebula, in a mosaic of the glorious region of the Milky Way called the Heart and Soul Nebulas located in the constellation of Cassiopeia. Two days ago I posted an image of the Soul Nebula. Here are both the heart and the soul of Cassiopeia the Queen.
