It's been a while since I posted an update on the Whispering Skies observatory project—for good reason: I've been busy imaging! But here's a recent update on some small projects and future ones planned: youtu.be/n2PlMcR0enE #astrophotography #observatory #astronomy

A new Imaging Project has been published on my website! Barnard 150 - The Seahorse Nebula (18.3 hrs LRGB) This was a bear to process because I used the wrong scope for this target! Full details, including process walkthu here: cosgrovescosmos.com/projects/b15... #astrophotography #astronomy

I'm pleased to share that two of my recent images were published in the Fall 2025 Issue of Amateur Astronomy Magazine: my shot of LDN 1235 - The Shark Nebula in LRGB, and my shot of M17 in SHOrgb! #astrophotography #astronomy

Thanks, BBC Sky At Night, for publishing my image of SH2-54m in the Serpent Nebula in their October 2025 issue! The original project post with all details can be seen here: cosgrovescosmos.com/projects/sh2... #astrophotography #astronomy

A new imaging Project has been posted to my Website! SH2-155 - The Cave Nebula - 13.5 hrs SHO (my 150th project!) Shot on my Sharpstar SCA260V2 & ASI2600MM-Pro & IOptron CEM70 mount. Full story and detailed processing walkthru: cosgrovescosmos.com/projects/sh2... #astrophotography #astronomy

A new imaging project has just been published on my website! LDN 1251 - The Rotten Fish Nebula (19 hrs in LRGB) Shot on my Askar FRA400 Platform w/ASI1600MM-Pro Camera & AM5 mount. Full story & detailed processing walkthru: cosgrovescosmos.com/projects/ldn... #Astrophotography #astronomy

IC 5070 - The Pelican Nebula (18.75 hrs in SHO) Just published on my website! I had 21+ hrs but thin clouds caused me to cull a full 2+ hours! Ouch! Full story and processing walkthru here: cosgrovescosmos.com/projects/ic5... #Astrophotography #astronomy

A new imaging project has been published on my website! Got to love a supernova! NGC 7331 and the Deer Lick Group w/ Supernova SN2025rbs (4.7 hours in LRGB) Shot on my Sharpstar SCA260 V2 Full story & complete processing details: cosgrovescosmos.com/projects/ngc... #astrophotography

Thanks Astronomy Magazine for choosing my recent image of SH2-124 as your "Image of the Day" I am honored! www.astronomy.com/picture-of-t... #astrophotography #Astronomy

Installed a new SkyAlert system for my Whispering Skies Observatory. It integrates with my SkyRoof System. See my post on this here: cosgrovescosmos.com/astrogear/sk... #Astrophotography #observatory #astronomy

SH2-124 is a faint HII emission nebula located 8,500 ly away in Cygnus. Little known & little studied, I found this region to be facinating. 14.2 hrs SHOrgb on FRA400 scope. Details & Process walkthru: cosgrovescosmos.com/projects/sh2... #Astrophotography #astronomy

A new Imaging Project has been published on my website! IC 5068 - The Forsaken Nebula and the “Black Waterfall”- (11.9 hours in SHOrgb) Must be seen full screen to appreciate the Black Waterfall! Full story & processing walk-through: cosgrovescosmos.com/projects/ic5... #Astrophotography

NGC 6543 - The Cat's Eye Nebula w/ NGC 6552 (14.6 hrs LRGB). Cat's Eye - 3000 lys. NGC 6552 - 390 M lys! Shot on SCA260 V2. Processing was a nightmare & stopped when I got tired of working on it! Full story & Process walkthu here: cosgrovescosmos.com/projects/ngc... #Astrophotography

M17 - the Omega Nebula. 17 hrs in SHOrgb. Disaster! 2 full nights of subs removed due to a focus glitch! AHH! Recovery: Skimmed a few hrs here & there & got it back up to 17 hrs! Full story with processing walk-thru here: cosgrovescosmos.com/projects/m17... #Astrophotography

Cool weather is ideal for some outside projects for the observatory! Painted the steel framework and mounted the shutters... #Astrophotography #observatory #astronomy

A new imaging project has been published on my website! LDN 1235 - The Shark Nebula - my 1st Dark Nebula target (7.4 hrs LRGB) Taken with my FRA400 Platform w/ASI1600MM-Pro. Full story and detailed processing walkthrough available here: cosgrovescosmos.com/projects/ldn... #astrophotography

I've been asked about how I made the sign for my Observatory. I have a new post that covers this topic here: cosgrovescosmos.com/observatory/... #astrophotography #observatory #astronomy

Ran a quick test of the Sharpstar SCA260 V2 on narrowband: 4.75 hours of SHO on M16. Ran into some SXT issues and some diffraction rings on 2 bright stars - see details here: cosgrovescosmos.com/projects/m16... #astrophotography #astronomy

The observatory is done. Now - what about finishing the outside perimeter & restoring the lawn? A new video on this effort can be seen here: youtu.be/GgWzij_EQtA #Astrophotography #astronomy #observatory

SH2-54, an HII complex in Serpens, resulting from 8.9 hours of SHO. Shot w/ my AP130/ASI2600MM-Pro platform from Whispering Skies Observatory. Full story & detailed processing walkthru at: cosgrovescosmos.com/projects/sh2... #Astrophotography #astronomy

Finally - after all of the clouds and smoke, we had a beautiful, clear, Moon-free night! Here, all of the scopes are programmed and waiting for dark and the rise of their respective targets! These are short nights - don't want to wait a moment of darkness! #astrophotograpy #astronomy

The sign is now mounted on the observatory, and the grass on the newly seeded lawn was mowed for the first time! Next: shutters, painting the door and steel! #Astrophotography #observatory #astronomy

I just received the sign for the new observatory! 36"x36" on 6mm DiBond. Printed with UV-resistant inkjet with a matte UV layer on top of that! #astrophotography #observatory #astronomy

A new video companion: "Setting Up My New Galaxy Scope: The Sharpstar SCA260 V2!" has been published on my YouTube channel. This augments my earlier blog post on this topic. It can be seen here: youtu.be/WvM6h8y2G90 #astrophotography

That's no Star Cluster! That's the Coma Cluster of Galaxies - over 1000 galaxies about 320 M lys away! Zoom & explore! 8.2 hrs of LRGB from William Optics 132 scope Full post here - w/ target details & processing details here: cosgrovescosmos.com/projects/com... #Astrophotography #astronomy

I recently did a presentation on my Whispering Skies Observatory Project for our local IS&T Chapter. It took the form of a video tour & interview - produced by Wayne Prentice. You can see it here: cosgrovescosmos.com/talks-presen... Hope you enjoy it! #astrophotography #astronomy

The NGC 5364 Group in Virgo. 6.3 hrs in LRGB taken with AP130 scope. 3rd image from my new Whispering Skies Observatory! Interesting collection of galaxy morphologies. Just wish the frame center wasn't empty! All the details: cosgrovescosmos.com/projects/ngc... #astrophotography

I was recently asked to give a talk to the St Albans Camera Club in the UK. The topic was "What it takes to make great images of the Deep Sky" A video of that Zoom Presentation can be seen here: youtu.be/GzWCEL2dr-0 Thanks, St Albans Camera Club! #astrophotography #astronomy

Markarian's Chain - 4.6 hrs LRGB taken on my Askar FRA400 platform. This is the 2nd image from my new Whispering Skies Observatory! Full details & processing walkthru at: cosgrovescosmos.com/projects/mar... #Astrophotography

Cosgrove's Comos has a massive curated resources page covering information concerning Astronomy & Astrophotography. Take a look: cosgrovescosmos.com/resources If there is a resource that you would like to add, let me know! #astronomy #astrophtography

While building the Whispering Skies Observatory, I placed a GoPro on a tripod every day and created a timelapse that boils months of construction down to 15 minutes! You can see it here: youtu.be/uMuLu-qIBDo #Astrophotography #observatory

M106 - 10 hours in HaLRGB. First light on the Sharpstar SCA260V2 and Whispering Skies Observatory! The full post, telling the full story - including detailed processing can be seen here: cosgrovescosmos.com/projects/m10... See full size for best effect! #Astrophotography

Hi Folks, I just published a post on the initial setup of my new "Galaxy" scope: Sharpstar SCA260 V2, IOptron CEM70, & ASI2600MM-Pro Camera. I even show a huge screw up I made. Learn from it! This post can be seen here: cosgrovescosmos.com/astrogear/sc... Thanks, Pat #astrophotography

First Light was had for the Whispering Skies Observatory on Tuesday night. As a maiden voyage, I expected some rough seas - there were some. But by midnight, all 4 scopes were gathering data. Good to be back in the GAME! #astrophotography

The construction phase of Whispering Skies Observatory is now Complete!! I just published a video on this on: youtu.be/hiqW-i8aQr8 While I have more projects planned for the observatory, my focus will now be on imaging!! #astrophotography

A video companion to my Blog post on stalling the Piers and Telescopes into the Whispering Skies Observatory has been published on my YouTube Channel. You can see it here: youtu.be/cs-clYQxmJM #astrophotography

The initial construction phase for the Whispering Skies Observatory is now Complete! Here is a quick drone video showing its current state: youtu.be/gAIoVmIWIsA Need clear skies to finish the setup & start imaging! More posts coming... #Astrophotography

A new post has been published on my Observatory Project! Whispering Skies Observatory: Installing the Piers and Scopes! This can be seen here: cosgrovescosmos.com/observatory/... #Astrophotography

Another update on the Whispering Skies Observatory Project has been posted! The work now is focused on the exterior and trim. As well as installing the telescopes. The update can be seen here: cosgrovescosmos.com/observatory/... #observatory #astronomy #astrophotography

Update on the Whispering Skies Observatory Project! I just mounted my new Galaxy scope on the 4th Pier! (Sharpstar SCA260 + IOptron CEM70) seen to the extreme left. It still needs a guiding system and a better camera - but that will be coming! #Astrophotography #Telescopes #Observatory

After my last post, I chose the OTA setup for my new Galaxy Scope but not my Mount. This new post explores my mount decision in more depth. It can be seen here: cosgrovescosmos.com/astrogear/4t... #astrophotography #telescopes #astronomy

I recently posted an article exploring my desire to put together a "Galaxy" scope for my new observatory to fill out the 4th Pier. You can see that post here: cosgrovescosmos.com/astrogear/4t... #astrophotography #Telescopes #Astronomy

A special milestone for the Whispering Skies Observatory! 3 of my scopes have now been mounted on their piers! Special thanks to Gary Villa & Glenn Cummings, who helped w/ the move & the setup! The 4th Scope awaits its mount before being installed! #astrophotography #Observatory #astronomy

Just getting back into town - before I left I tried getting my piers up to the observatory on my own - but they were too heavy! Especially in he heavy snow! Trying again later this week with the help of friends! #astrophotography #observatory

Cosgrove's Comos is beginning a shift from X over to Bluesky! Stay tuned for my future posts on the Whispering Skies Observatory Project and new posts - Website: CosgrovesCosmos.com YouTube Channel: www.youtube.com/@cosgrovesco... #astrophotography
