Observatory Update: Breaking Ground! Excavation Complete!
Переглядів 338Місяць тому
After a very long effort, my observatory project is now getting under way! We have now broken ground! Over a period of two days, the Excavator did a great job in removing topsoil, creating a level building pad that was 3' larger than the observatory footprint, and laying a bed of compressed gravel! This video attempts to show the work that went on over two days in just a few minutes! Next, we w...

This is a video companion to a blog post I wrote a few days ago about the roof opening system for my observatory project. This blog can be seen here: cosgrovescosmos.com/observatory/opening-the-roof In previous videos, I have talked about hardware selections for the roof tracking system - in this one, I talk about my selection of the SkyRoof System by InteractiveAstronomy.
Observatory Update: Final Roof Track System Hardware Selections!

This video is the next in a series documenting my Rool-Off-Roof Observatory Project. While a previous video showed my initial thinking on hardware selection - continued research caused me to change some of my selections to get a more cost effection and capable set of hardware. Most of this hardware is now in hand, and I wanted to share a quick video showing where this came out. Note that after ...

Переглядів 2262 місяці тому
As part of my Observatory Project, I am building 4 custom telescope piers from Steel. This shot shows the bottom flange and the top plate being cut from 1/2-inch plate steel using a 4000-watt CO2 laser! It does an amazing job with really clean edges! You can see how the piers were designed here: ua-cam.com/video/9KCKRyNYWWA/v-deo.html A full report on the cutting of these parts will be posted i...

This video complements my blog post describing the design of 4 custom piers that I will be making for my observatory build. That blog post can be seen here: cosgrovescosmos.com/observatory/piers-1 In this video, I share my thinking on what piers I will use for the four telescopes that my observatory will support. While I started with concrete piers in my design, I have since shifted to the crea...
Observatory Project: Galvanic Corrosion and a Change in Track Selection!
Переглядів 3473 місяці тому
In my previous video, I talked about my hardware selections for the Roof tracking system. After that, I ended up doing some research on Galvanic Corrosion, which ultimately caused me to change my track hardware selection. This video will discuss what Galvanic Corrosion is and why I changed my track to prevent issues. At one point in the video, I show a table of metals that can cause this effect...

My Observatory Quest: Sucess! The Search for Larger Skies!
Переглядів 4494 місяці тому
In my last video on the Observatory Quest, I shared the design I had developed for a Roll-Off-Roof Observatory. In this video, I will discuss our search for land over two years, how we had a mid-course correction on what we were looking for, and what we ended up with! I hope this might be of some help to others who are starting a similar search. This video is a companion to several blog posts o...
Designing my Roll-Off-Roof Observatory!
Переглядів 8864 місяці тому
For the past two years, I have been on a quest to build my own observatory. This quest was complicated by the fact that I not only had to design the observatory but also needed to find land suitable for this project. We finally found the property that would meet our needs! We have moved, and now I am beginning to move forward with the project. While I have blogged about this effort on my websit...

I have not been creating new content for a while - and that is because my wife and I finally found a new property that would allow me to build my observatory! We placed the offer in mid-October, and since then, we have fallen down the rabbit hole - totally absorbed by the work to close on the new house, packing and moving, prepping the old house for the market, and so on. We are just coming out...
