    The Lagoon Nebula ( Messier 8, NGC 6523 ) in the constellation Sagittarius - by Mike O'Day ( https://500px.com/mikeoday ) The Laboon Nebula ( M8 ) is visible to the naked eye under dark skies from most latitudes except the far north.

  4. Also known as the Theta Carinae Cluster, The Southen Pleiades is a very bright open cluster in the Carina constellation. It was discovered by Abbe Lacaille during his visit to South Africa in 1752. Containing around 60 stars, IC 2602 shines with an overall magnitude of 1.9 and its brightest member is Theta Carinae with a visual magnitude of 2.7. This cluster of young blue stars is relatively close to us at "only" 479 light years. 5 May 2018 The Southern Pleiades ( IC 2602 ) in Carina ( please click / tap on image to see larger and sharper ) .........

  5. The Jewel Box ( NGC 4755 ) is an open cluster of mostly hot young blue-white stars that appears to the unaided eye as a bright 4th magnitude star close to the Southern Cross. Only visible from southern latitudes, the Jewel Box was first recorded by Nicolas Louis de Lacaille during his visit to South Africa in 1751 and was later described by Sir John Herschel as "a casket of variously coloured precious stones" - hence the name "Jewel Box".

This led me to wonder if there was a way I could display my images on a single page together with a few notes on the target object as well as few technical details of the capture for those who might be interested. What I came up with a "scrapbook" like page that combines all of these three elements in a single PDF sheet ( or jpeg image) that ultimately I might combine together to form a PDF book that I can share online or send to friends and family. In the meantime, I thought I might post in this thread each page of my work-in-progress towards volume 1 of my Astrophotography Scrapbook. Any and all comments, observations, suggestions and constructive criticisms will be warmly received. Cheers Mike ps. The pages have been sized to fit full screen on an IPAD

  17. Re-processed 3rd March 2018 - no luck so far getting any more data; I will try again when the moon goes away ....... With my unmodified D5300 DSLR, the HII nebula Gum 15 is barely brighter than the surrounding diffuse red glow that surrounds it and it all sits way down in the noise. I decided to share this small WIP version as I think it may be a while before I can get the data I need to impove it. This one has way too much noise ( and hence quite heavy noise reduction / smoothing ) as the detail is very faint and I needed a massive stretch to pull it out - more data will help with that I think.

  18. NGC 2014 and Dragon's Head nebula in the Magellanic Cloud ( LMC ) not far from the Tarantula Nebula by Mike O'Day ( 500px.com/MikeODay ). This image shows multiple bright nebula and star clusters in an area adjacent to the The Tarantula Nebula ( NGC 2070 ) in the nearby irregular galaxy, the Large Magellanic Cloud ( LMC ). The largest of these are the bright pink nebula in the mid-right part of the image ( NGC 2014 ) and the blue nebula in the lower middle ( NGC 2030 ). ..... Updated image - reprocessed to impove colour balance ( April 15th ) ( please click / tap on image to see it larger and sharper ) .... Original: ( click on image to see larger and clearer ( grrr... image compression in version above )) ---------- This is the first image captured as part of a new image capture and processing workflow I am trying out... Roger Clark ( http://www.clarkvision.com/articles/index.html ) has a number of articles addressing colour processing and the performance of modern DSLR sensors. The "take homes" for me have been: 1. With a modern sensor ( one with on-sensor dark current suppression technology ) one may not need to capture dark frames ( in order to remove the now non-significant pattern noise ). 2. "Correct" white balance processing should start by using "daylight" RBG channel multipliers ( to get the star colour 'right') and any histogram adjustment to improve white balance of darker parts of the image should involve aligning the left side of histogram curves ( ie. not the peaks ) So, the workflow to produce the image above involves calibraiton with Superbias & Master Flat but no dark frame subtraction (neither post nor in-camera). Roger Clark speaks of using a "bad pixel map" as the basis of reducing hot pixels. I have not figured out how to produce one yet. However, with a little bit of dithering during guiding ( and the very busy image ) the hot pixels that are in the image below are not too overwhelming. With regard to colour balance; I tried using the "daylight" factors reported by the camera but these resulted in an image and stars that were quite blue. This image was based on the factors reported by DXOMark for the Nikon D5300 ( R x 2.12, G x 1, B x 1.49 ( D50 standard )). This was better but I still felt the need for a final tweak in Photoshop ( colourBalance Highlights +15 Cyan/Red, -5 Magenta/Green ) to improve the colour in the stars and mid-tones. { DXOMark "white balance scales" for D5300 found at: https://www.dxomark.com/Cameras/Nikon/D5300---Measurements on the "color response" tab } --------- Details: Bright Nebulae: NGC 2014 ( upper right, pink) size 30 x 20 arcmin Mag +8 NGC 2020 size 2.0 arcmin ( small blue-green oval nebula ) NGC 2030 NGC 2032 ( Dragon's Head nebula - blue, central bottom of image ) NGC 2035 size 3.0 x 3.0 arcmin NGC 2040 size 3.0 x 3.0 arcmin Open clusters: NGC 2004 size 2.7 arcmin Mag +9.6 NGC 2011 size 1 arcmin Mag +10.6 NGC 2021 size 0.9 arcmin Mag +12.1 Annotated : Image centre RA 05h 33m 32.362s, Dec -67° 32' 18.145" (nova.astrometry.net) Orientation: up is west, right is South Field of view (arcmin): 58.8 x 39.2 Scale (full size image) 0.585 arcsec/pixel Telescope: Orion Optics CT12 Newtonian ( mirror 300mm, fl 120mm, f4 ).
