Description

INTRODUCTION & BACKGROUNN- One of the best parts about being a teacher is having the summers off. A little over a year ago I decided to commit to a new hobby, I spent all of last summer learning about amature astrophotography, building my first imaging setup, and taking my first images through a telescope. It was an amazing and productive 3 months. Having all that dedicated time allowed me to become fully invested in the difficult process of imaging the cosmos. It is now a year later and I wanted to celebrate by sharing something that I really could be proud of. Most nights I can collect enough data to put together a decent photo. However, I wanted to capture something special this time, something that was new that challenging. I also wanted to integrate everything that I've learned this past year through tons of research, practice, meticulous & frustrating troubleshooting, trial & error, and the help & support from you guys; the Astrobin community. This image features the core region of my second favorite DSO, Messier 8. I recently shared my true color image of the large Lagoon nebula which is a common target for Astrophotographers. However, these wide view images never seemed to do justice for me especially after being blown away by Hubble's 28th anniversary release of the Hourglass within M8 (https://www.spacetelescope.org/news/heic1808/). The structures and detail within this area are much smaller and difficult to resolve. The glaring full moon also posed a challenge by restricting me to narrowband imaging, something I have never tried or was even equipped yet to attempt. I decided to try using a new dual band pass filter with my OSC camera to acquire the data needed to create this image. I had strictly used the Optolong L-pro filter for the past year and after my first night using the L-eNhance it because apparent that I would have to completely revise my usual acquisition and post processing work flow process. After a week of trial and error in both of these stages I finally got it! So I am happy to share with you guys, my "One Year of Astrophotography" image, "The Hourglass".

Thanks everyone for your love and support,
John Michael Bellisario
