  1. The whole of Delphinus

    Here is the Noel Carboni version. Greg
  2. The whole of Delphinus

    Got this 2 nights ago with the 200mm lenses and 2600MC Pro CMOS cameras. 28 x 10-minute subs on the Delphinus region. Greg
  3. Noel Carboni has been applying Russ Croman's StarXTerminator software to some of my old data. Here is an extremely interesting example of what can be done. This is the region from the Gamma Cass nebulosity down to the PacMan nebula in Cassiopeia. In the starry image you can only make out the brightest parts of the Gamma Cass nebula. In the highly reduced stars image you can actually see the full extent of the crashing wave. I find this result quite remarkable. It shows that in the right hands Russ Croman's StarXTerminator can completely revolutionise your nebula image processing. Greg
  4. StarXTerminator as a processing tool

    For his demo of STarXTerminator Russ Croman uses the Veil Nebula. The attached image shows why this one is a good choice. Greg
  5. The Horsehead nebula and the Belt Stars of Orion region. This is a 2-frame mosaic using a single Sky90 and a single M25C OSC CCD. H-alpha and OIII data was also included. Imaging time around 4-hours (or more) per frame. This version is with the star reduction app that works with Russ Croman's StarXTerminator Greg.
  6. Detailed Image of Dragonfly Eye November 21, 2022 You saw it on here first Greg https://epod.usra.edu/blog/2022/11/image-of-dragonfly-eye.html
  7. Star reduced IC410/405

    My free trial of Russ Croman's StarXTerminator ran out, so I just bought the full licence In celebration I ran it on an old Sky90/SX M26C image of IC410/IC405 which was 34 subs at 20-minutes per sub. In this version the tadpoles are clearly seen top-left of the left hand nebula Greg.
  8. Star reduced IC410/405

    It was 76 x 15-minute subs on the 200mm lenses, so it's 29-hours and NOT 39-hours for the total exposure time. Greg
  9. Star reduced IC410/405

    And this is a composite image comprising 34 x 20-minute subs on the Sky90s and 74 x 20-minute subs on the 200mm lenses. A pretty mediocre looking image seeing as there's 39-hours worth of data in there!! Maybe Noel Carboni can turn out something a bit better. Greg
  10. StarXTerminator as a processing tool

    Very nice Tim! Greg
  11. Processing DSS images

    Attached is an image of the Sadr region I processed this afternoon from DSS data. Making your own images like this is EASY. Go to the Skyview Query Form and download the Red and Blue FITS files from DSS2. Using Noel Carboni's Astronomy Actions there's a "Create RGB image from FITS channel files", this needs you to have FITS Liberator talking to Photoshop which can be a project in itself. Having created an RBB image (you put the blue channel into the green channel as there is no green filter for DSS data), you then go to "Create a synthetic green channel" in Noel's actions and you will end up with a fairly decent RGB rendering of your object. Then it's just a matter of doing your usual image processing steps to tart up the image. Good luck. Greg
  12. Star reduced Great Orion Nebula

    As per the title Greg
  13. Star reduced Jellyfish nebula

    As the title says Greg
  14. Star reduced Veil nebula

    This time the Veil nebula in Cygnus gets the star reduction. Greg
  15. Star reduced IC1396

    As per title, Greg
  16. Star reduced IC410/IC405

    You may (or may not remember) that quite a while back I took an image of the IC410/IC405 region using the 200mm lenses and 76 x 15-minute subs - and I was very disappointed with the result. Well Noel Carboni ran the star reduction routine on it using Russ Croman's StarXTerminator - and this was the much more acceptable result. Greg
  17. Hah - no Ray, I am not set up for that - these are all commercially available pre-prepared slides. Greg
  18. Another pair of photomicromosaics (no focus-stacking). This time a Thyroid Gland (unknown creature) with 9 frames and a magnification of x20, and a Spinal Chord (again, creature unknown) with 19 frames and a magnification of x50 Greg
  19. Here's a rather unique blast from the past. This is a microscope stereoscopic view of Cabbage White Butterfly eggs. Mag x20, single frame, top illumination using fibre-optic lamps. The stereo image was assembled by Dr. Brian May (the Queen guitarist) who is also a stereoscopy expert. You can view the image either by using Brian's OWL glasses, the prism glasses from the Widescreen Centre, or by the "cross-eyed" method. Greg
  20. Star reduced Cygnus Wall

    DSS image replacement. Greg
  21. Star reduced Cygnus Wall

    Here is a star reduced Cygnus Wall image. And yes I've cheated The easiest way to produce a nice image of the Cygnus Wall with tiny stars is to process some DSS data. Greg
  22. Star reduced Cygnus Wall

    My awful image has been replaced with a beautiful DSS image Greg
  23. Star reduced M31

    Using Russ Croman's StarXTerminator to remove stars from an image so you can the create just a star image to work on (drastically reduce the stars) allows you to turn a rather busy M31 image - into this Greg
  24. Here is another double water drop collision captured in 10-microseconds. Greg
