All Gear Posts
In order to “do” astrophotography, you can’t get around the need for gear!
On this page I will document the Telescope Rigs that I use to capture my images. One thing to keep in mind is that these rigs are NEVER static. They change and evolve over time. I will try to document those changes here. This has a few practical goals. First - it will document what state the rig was in when a given set of images were taken. Second, it will give you a feel for how things evolved as I progressed on this journey. Finally, it may give you ideas for your own rig!
In General, I am running three Telescope Platforms - typically all at the same time - to enable my imaging Projects. The First is the William Optics 132mm Platform. This is based on the first scope I used for imaging. The second platform is the Astro-Physics 130mm Platform. This second platform was unplanned and came about through a unique and fortuitous set of circumstances The third and most recent platform is the Askar FPA400 Platform - which was put together to enable both portable operations and more wide field capability.
The stories of these platform is found in this blog along with other pieces of equipment that greatly facilitate my astrophotographic endeavors.
Ever wonder what I go through when setting three telescopes up in my driveway for each night of imaging?
Wonder no more!
I strapped on a GoPro Camera and captured my set up process!
Version 2.0 of my Askar FRA400 Platform consists of a switch in mounts! I have gone from an IOptron CEM26 mount to a new ZWO AM5 Harmonic Drive! This post documents and discusses this change in the platform.
As you assemble and evolve your telescope platform, you can expect to have to deal with routing cables to feed power and USB connection. It’s easy to end up with a rat’s nest of cabling that can have a negative impact on your imaging. With this post, I share how I deal with this problem. Hopefully, it will give you some ideas as your wrestle with your cabling challenges.
I have a powerful desktop computer that I custom-built expressly for Pixinsight image processing. However, I have been spending extended periods out of town and wanted to have a smaller form-factor computer for travel that was just as powerful. This post discusses that built.
Running three telescope platforms at the same time can generate a lot of data. Processing that data with the some of the sophisticated algorithms used by Pixinsight can make great demands on your computer. In response to this, I built a new computer that would be better optimized for Astro image processing and storage and networking strategy that would handle the workflows, data loads, and demands of astrophotography.
When you are running three astrophotography telescopes in the driveway at the same time, you have a lot of gear that has to be moved into position - plus I needed a place for the laptops that control my scopes. I built this Astro Cart and computer desk to help me deal with that. A very simple and useful project!
After much research, and a few phone calls to the helpful friendly folks at Highpoint Scientific , my first rig was on order! Within a week I had everything I needed to start doing astrophotography. But of course, I had no real clue how to actually do ANY of it. I barely knew how to put the pieces together much less make them work. This was the start of my journey.
The start of a second imaging platform - or - how tripped into the deal of a lifetime !
I was still learning to use the main rig, when I soon made my first modification. I was doing the Polar Alignment the old fashioned way - using an illuminated polar scope. This caused me to kneel down on the driveway and look up through the polar axis. This was killing my knees, my back and my neck! I hated it and I was sure I was not getting very good alignments with it…..
Over the winter, I began to get things ready for the second platform. Clearly I had some work to do. I needed to determine what I was going to do for a camera, and I needed to determine what to do get the mount functioning at the precision needed.
Standardizing the base
Finally, the Tri-Pier and the its extension column arrived. This allowed me to standardize the base of the two telescope platforms. There are several reasons that made this useful. First - everything is the same when you are handling things in the dark. And secondly, I was in the process of revolutionizing how I setup at night…..
During August and September I was out shooting every clear night. I had learned a lot of things but I was also noticing several issues that were causing me problems as I did more imaging. I decided to do something to address those issues….
Why a focuser for the Guidescope?
Basically I am making this change to make the platform consistent with the WO132 platform. I would like to be able to focus the guidescope remotely under computer control. I would also like to have the ability to swap camera and use the TV76 as a wide field imager (using the AP130 as the guide scope.
Adding the next generation ZWO ASI2600MM-Pro camera and ZWO EFW 7x36 II EFW to the platform…
During the Summer of 2020, whilst stuck at home because of Covid I became very in improving the automation of the platform and achieving a more precise framing of the shots I made…
For Christmas of 2020, my wife gave me a neat little wide field scope - the Sharpstar 61EDPHII! This little scope came with a Reducer/Flattener and would make a great wide field Astrograph. So I thought about how to use it.
I was very excited to get the ZWO ASI2600MM-Pro camera a while back. I ordered it when it was announced and then prepared to wait a long time to get it. When I did get it - I decided to put it onto the AP130 platform. That meant that I could move the ZWO ASI1600MM-Pro, along with its filter wheel over to my William Optics Platform. This now means that all of the platforms have been moved over to a mono camera and my ZWOASI924MC-Pro is now not in use.
Version 4.0 of the Williams Optics 132mm platform is a major upgrade that involves adding a new 2600 series mono camera, a new 7x36mm EFW and filters, and a new WO Flattener and 0.8X Reducer that will support the larger format sensor and covert the scope to a much faster f/5.5 system.
This post documents the changes and discusses how I planned this change and how it was executed.
This is my third telescope platform - this one is specifically designed for portability and travel.
The portable scope platform is supposed to be, well, portable. That means light and compact. In determining how to pack this platform for travel, I realized that the finder scope mounting rings made no sense in this application and I changed them out with something both more rigid and compact - the William Optics 50mm base-slide ring set.
After doing manual camera rotations to achieve the compositional framing that I plan - using SGP’s Framing and Mosaic Wizard - I finally decided to add a Camera Rotator to this rig to automate the rotation between objects and when getting flat cal frames for images shot with a specific camera rotation. While I had the rig apart, I re-tensioned the declination belt on the mount to reduce declination backlash.
The security camera caught me setting up for a night of Astrophotography running two telescopes simultaneously. Many people have asked me how I go about this and I thought this might be an opportunity to show them. So I accessed the motion triggered video snippets from the security camera and using my non-existant video editing skills - I made my first movie. Its kind of fun to watch and I added a nice montage of some of my work at the end.
I image from my driveway. Setting up two large telescopes for each night’s astrophotographic efforts - and then taking them down again at the end of the evening was too much work. Wit the help of a talented friend, I build a Telescope Lift/Transporter. This device wheels up to my Tri-pier, clamps on to it, lifts it off the ground and then lets me move it to precise points of drive. This way the scope is ready to go at a moments notice. This post describes the design and the build process.
I just moved to a new house that will allow me to finally build the observatory that I have been wanting - and in the process, I ended up having a new large space where I could set up my office. So I used this unexpected opportunity to build my Dream Astrophotography Man Cave! See what I did and how it came together. Maybe you will find a few ideas for your own workspace!
