The Telescope

Comet Neowise and the Great Conjuction in 2020 made me think about the telescope I’ve had in the closet for many years. I’m happy with the images I made of those two events, but I regret not trying to use the scope to photograph them.

I’d only ever used it for observing. Photographing through a telescope requires a much higher level of knowledge and technical skill. In addition to knowing how to set up and align the scope and camera, you have to understand and balance many more factors: camera (ISO, aperture, exposure time, focus, …), astro (atmosphere, alignment / tracking, field rotation, …) and post processing. So I thought I’d try a couple of shots to see what it could do.

Moon
Earth’s natural satellite. Using a Sony DSC-RX100M3 camera (1″ sensor), afocal through Celestron NexStar6 SE scope and 40mm eyepiece; Thirteen frames, manually aligned in photoshop and blended with smart stack mode median.

I used the moon to get everything set up and tested. Next I wanted to try to photograph a Deep sky object. They’re plentiful, but harder to find or even see. I picked the Orion Nebula as my second target – it’s probably the easiest DSO. Even here in my back yard, Orion’s belt stands out.

Orion Nebula. Same setup as above, using six frames instead of thirteen.

I know these aren’t Hubble level images or even very good amateur astronomer images. But I’m pleased with how they turned out. I want to continue exploring photography with the telescope and see how well it can work in my urban (and light polluted) environment. If I make some progress, I’ll share the images with you.

Thanks for stopping by and reading my blog. Take care of yourselves and each other. And if you can – make some (astro) photos!
