Comet Academy
All of the content is found by scrolling down this page.
Horizons subscribers can access the videos below. New customers can purchase the standalone Comet Academy for $75 - (<- follow link) If you like Comet Academy and are considering a Horizons subscription, you can apply the full $75 to unlock all videos in Horizons. Please one credit towards Horizons only. HERE IS THE CODE (available after purchase).
Reminder: It is recommended to watch the Fundamentals videos for a complete understanding of all image processing in Horizons. |

Explanation of Comet Subtraction Alignments |
If you want to take your planning and observations to the next level, consider joining the: |
DSLR Comet Example (C/2023 Tsuchinshan-ATLAS Guide and Processing Demonstration)
CFA/OSC (This astrophotograph became a NASA Astronomy Picture of the Day!)
The Use of Russ Croman XT software is a central part of the processing workflow. Buy the software from the links below. (SXT is minimum requirement.) |

Found below are demonstrations and complete PDF guides with data to follow along. Currently there are 5 examples below and two additional at the bottom of the page-- more to be added. Please watch BOTH CometAlignment explanations above before proceeding. |
Standard Comet StarTracked, Mono, RGB, Background Nebula/Galaxy, Comet Subtraction

C/2021 S3 (PanStarrs)
This comet is particularly challenging because it is moving against a background of nebulae that will not cleanly reject during the creation of a comet-only image. Special considerations demonstrated and section 4 below regarding Structure Removal are key. Data available below. |
