The Feb Issue of Astronomy Mag came out today, featuring my image of SH2-124! Thanks, Astronomy Mag! See the imaging project for this image here: cosgrovescosmos.com/projects/sh2-1… #astrophotography

NGC 2174 — the Monkey Head Nebula — is live on Cosgrove’s Cosmos. 5.1 Hours in SHO. Captured as a “bonus target” after my primary target set - love those long Oct nights! Full capture details + processing walkthrough here: cosgrovescosmos.com/projects/ngc21… #Astrophotography

A companion video to my post on transforming the N wall of my Whispering Skies Observatory has now been published on my YouTube Channel! This describes the background to this build & shows the build itself! See it here: youtu.be/01tFTLSVj3U #astrophotography #observatory

🚀 Cosgrove’s Cosmos Resource Hub is upgraded! Cleaner layout + focused sections for observers & imagers: targets/catalogs, sky events, gear, software/processing, and more! Bookmark it: cosgrovescosmos.com/resource-hub #astronomy #astrophotography

Why 4 telescopes? One is never enough, Eight is… a problem. 😄 Building my four-platform observatory “arsenal” — the role of each scope & how the set covers everything from wide nebulae to tight galaxy framing. cosgrovescosmos.com/astrogear/over… #astrophotography #observatory

Less Saw Dust, More Photons! You've seen my build videos for the Whispering Skies Observatory. This one is an overview of the final product. cosgrovescosmos.com/astrogear/whis… #astrophotography #Observatory

Astrophotographers - Help Needed! I've been building an astronomy & astrophotography resource list for years now. I recently curated a 'quick start' list for beginning imagers. Could you review & suggest improvements? URL: cosgrovescosmos.com/resources/star… Thanks! #astrophotography

I have also created a Quick Start Resource Guide for those new to Astronomy. You can see that here: cosgrovescosmos.com/resources/star… Please review & suggest improvements! Thanks!

I just upgraded my Askar FRA400 Telescope platform with a new ASI2600MM-Pro Camera & a Wanderer Astro V4-EC 125mm Motorized Cover. A full post documenting the upgrade process can be seen here: cosgrovescosmos.com/astrogear/fpa4… #astrophotography

What Kind of Astrophotographer Am I? (What Kind Are You?) I was trying to find a way to summarize this for myself, and I ended up w/ a little summary panel & Radar Plot. See this here & see what you think - make one for yourself! cosgrovescosmos.com/what-kind-of-a… #astrophotography

Upgrading my Astro-Physics 130mm EDT f/8.35 platform to its big brother, the Astro-Pysics 155mm EDFS w/0.75X reducer @ f/5.3. I also added a Wanderer Cover V4 EC 190mm to this. See the build sequence here: cosgrovescosmos.com/astrogear/ap15… #Astrophotography

New tool on Cosgrove’s Cosmos: The Telescope Platform Card Builder! Create a polished downloadable card for your imaging rig w/ gear details, images, & computed values. Free to use, and I’d appreciate feedback. You can see it here: cosgrovescosmos.com/astrogear/plat… #astrophotography

I recently shared details of the countertops & cabinets I installed on the N wall of my observatory. Some thought this was overkill. Not at all! Here is my first project on it, converting my AP130 platform over to an AP155! Just big enough! #astrophotography

W/ my project to convert my AP130 platform to the AP155, I began to dial in the scope. scope config. Then - loud fan noise & physical vibrations from my ASI2600MM-Pro! Investigation showed the fan had thrown a blade! Replacement is 3+ weeks out! #Astrophotography

New video on Cosgrove’s Cosmos: I converted my AP130 imaging platform into an AP155 platform — this turned into more than a simple scope swap. If you enjoy the gear side of astrophotography, this one is for you. youtu.be/oqLwUUrGWow #astrophotography #telescope
