Deep-Sky Winner: 11 - IC1805 / Heart Nebula - Jeff Donaldson

$28 - Aristoteles and Eudoxus, the 'Bike Wheel' lunar craters. SS Aristoteles and Eudoxus, the “Bike Wheel” lunar craters.•\tThe Aristoteles and Eudoxus craters.•\tAristoteles and Eudoxus craters are prominent; however, the image also shows some of Mare Frigoris and the northern part of the Caucasus Mountains and Mare Serenitatis, including the impressive Posidonius crater. Aristoteles and the smaller Eudoxus are a distinctive pair of craters joined by an arc of mountains. Together, these two craters and mountains resemble a bicycle and rider. .•\tCaptured at 05:16 on 7 September 2020 at Halifax, NS. Equipment consisted of a Celestron C8 200mm f/10 Schmidt-Cassegrain telescope, SkyWatcher EQ6R mount, and a ZWO ASI290MM CMOS camera (gain 200, 0.0125-second exposures, MONO8/SER format) with an IR 850nm pass filter at prime focus. SharpCap was used to capture 4000 frames of video, the best 200 of which were selected and stacked with AutoStakkert 2. Registax 6 was used for wavelets. Levels, sharpness, contrast, highlights and shadows were tweaked using Photoshop CS2 and Microsoft Photo.$ Solar System Winner: 28 - Aristoteles and Eudoxus, the 'Bike Wheel' lunar craters - David Hoskin.

$13 - The Heart Nebula melts my Heart Image Title: The Heart Nebula melts my Heart..Object: The Heart Nebula (IC 1805)..Pertinent Details: This was my 1st target with my new Triad Ultra Quad Narrow band filter and I had no idea how it would perform, particularly as the 1st night of shooting was under a nearly full moon. I love photographing things we normally can't see and this is clearly that type of target...Capture Details: Image sub-frames consisted of\t56@300 sec + 14@600 sec + 23@900 sec, for a total of 12.75 hours. Shot at ISO 800 on a Nikon Z7 [8856 x 5504] using a Skywatcher Esprit 120mm Refractor with a Radian Triad Ultra Quad-Band Narrowband Filter (H-beta, OIII, H-alpha, and SII). Guiding used Phd2 via a ZWO 224MC on an Orion 60x240mm Guide scope. The image sequence was controlled using Kstars on an Odroid-N2 (Raspberry Pi clone) in suburban Nova Scotia between 2020-06-16 and 2020-09-05. PixInsight Processing consisted of the following processes: the WeightedBatchPreprocessing Script for calibration, registration and integration (integration used the Generalized Extreme Studentized Deviate rejection algorithm), Dynamic Crop, Automatic Background Extractor, ColourCalibration (both saturation and hue), MultiscaleLinearTransform, HistogramTransform, CurvesTransformation, LocalHistogramEquilization and ColourProfile. Further tweaking for colour was performed in Lightroom. Sorry about the saturation, but that's the way I like it.$ 13 - The Heart Nebula melts my Heart

$26 - The Iris Nebula (NGC 7023) DS NGC 7023.•\tThe Iris Nebula (NGC 7023).•\tThe Iris Nebula is a bright reflection nebula located in the constellation Cepheus.

DeepSkyStacker was used to debayer and stack 30 x 4-minute subs, 30 darks, and 30 flats. Photoshop CS2 with Astronomy Tools Action Set was used to adjust levels, stretch data, increase saturation, and remove noise. ImagesPlus was used for star reduction. Microsoft Photo was used to tweak clarity, contrast, highlights and shadows in the final image.$ 26 - The Iris Nebula (NGC 7023)

$14 - The Eagle watches over us Image Title: The Eagle watches over us..Object: The Eagle Nebula (M16)..Pertinent Details: The Hubble version of this target featuring the 'Pillars of Creation' has always been the most stunning astro image I've encountered. With a new Triad Ultra Quad Narrow band filter, I wanted to see what I could capture from light polluted skies. This young open cluster of stars, gas and dust draws me into its center...Capture Details: Image sub-frames consisted of\t6@300 sec + 1@600 sec + 12@900 sec for a total of 8.25 hours. Shot at ISO 800 on a Nikon Z7 [8856 x 5504] using a Skywatcher Esprit 120mm Refractor with a Radian Triad Ultra Quad-Band Narrowband Filter (H-beta, OIII, H-alpha, and SII). Guiding used Phd2 via a ZWO 224MC on an Orion 60x240mm Guide scope.
