I decided to do some research on the options to connect my Canon DSLR to the Meade LX70 Refractor. I had a special adapter for the ETX 90EC that allows the Canon to connect along with a T-mount adapter. So, I first searched for adapters for the LX70 but didn’t find any. I did find that Meade sold a camera adapter that connected to a DSLR and then went in the 1.25” eyepiece holder. This sounded like a great idea because I could then use it will all my telescopes.
I did some more research and found a great article about taking lunar photos through a telescope. The article mentioned three ways. One way was afocal photography which I was aware of. The camera adapter would enable eyepiece-projection photography. This was interesting because it actual uses an eyepiece so would allow for different magnifications. But the drawback in the images are dimmer.
The third option was prime-focus photography. I guess this is what I am doing with the Canon and ETX. The article mentioned you could buy adapters for many telescopes so started doing that research. I found a number of options including adapters that already had the T-mount. But, then I had a thought. There was a part in the box for the LX70 Refractor that I didn’t know what it was. I took the T-mount adapter and tried to screw it on to the mysterious adapter. It worked. I then put in on the diagonal and it all works. I added the Canon and tried to focus on a distant power pole. I couldn’t get focus similar to what happened on my Lunt. I guess it was time to research extension tubes.
But, then I had a thought. The diagonal was removable so I took it off and added the DSLR and adapter to the back of the refractor and it all worked. I was able to get a focused. So, guess I already have everything I need to use the DSLR with the LX70 Refractor.

The night before was clear but I forgot to take out the ETX to cool before getting back from walking the dogs. But tonight I took it out during dinner. I connected the Canon after dinner and looked for Saturn. It was in the southwest and was almost behind the tree. I moved the tripod and took some images. I struggled trying to remember the settings on the Canon and accidently erased the memory card. Opps!!
But, I did get images of Saturn and the Moon. I looked at the images on the computer and Saturn was blurry but the moon wasn’t that bad.

I went to Madras, Oregon to view the total solar eclipse at Oregon Solarfest.
I setup a couple of cameras. The first was using a solar filter over a telephoto lens on my Canon. I took a couple of shots during the first contact phase. The main effort was using the Lunt and ZWO to try to capture totality. The last was using the Canon to record a video during the event pointed at the horizon. The results are located in the articles wiki for astrophotography events for the total solar eclipse.
The video of using the Lunt and ZWO didn’t turn out. The still images are great but the video needed some different type of exposure settings. The view from the Canon was fine but the video of the event using the Canon was great. Like I read, it was great to record the surroundings and our reactions to the event.
The total solar eclipse itself was incredible to see with my own eyes. I am sure with more practice I could figure out the exposure settings but it was just incredible to experience though way too short. I was also amazed by the temperature change. Didn’t expect that.
Lastly, here are some news videos for the place we camped and nearby:

I recently attended the Table Mountain Star Party. With the dark skies, I was able to try to take some night sky photos of the Milky Way. I read the book Photography: Night Sky: A Field Guide to Shooting after Dark by Jennifer Wu and James Martin. One of the chapter is the book is Stars as Points of Light. I used this chapter as guidance to set my Canon T3i. I created an article explaining my camera settings to take a night sky photo.

I experimented with connecting a Canon T3i to an ETX-90EC. I purchase the necessary T-apdater for the ETX along with the T-mount for the Canon. The connections all went fine. I focused in the eyepiece and the flipped the mirror. I add to refocus for the camera. The first images were okay.
I looked up in the Canon manual how to get the Live View not to turn off too quickly. I then read the section on Live View and learned how to manually focus. It was much better once I learned how to zoom in on the Live View. The automatic focuser was great but still not sensitive enough. Later, I found out there are speed settings on the focuser so will have to try that.
Overall, the configuration worked fine and ready to test on astronomy objects.

In my planning for future purchases, I wanted to eventually get a CCD camera but I knew that is a ways off. In the short-term, I wanted to get a starter astrophotography camera but decided to go the more traditional route and use a DSLR with a telescope. I did some research and found the Canon T3i to be a good starter camera that would work with the ETX-90 and also work for a family camera.
I added to my Amazon wish list and monitored the price. Over the winter holidays, the camera went on sales as a bundle with a telephoto lens so I purchased it.
The camera out the box was great. The manual had a bunch of controls and settings but the auto mode worked fine too. I purchased a view accessories right away:
- carry bag
- small tripod
- lens cleaning kit
- memory cards
- spare battery
- camera pouch
- book about camera
