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

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
