Intriguing object spotted while looking at Saturn Friday evening

October 07, 2017 @ 01:44 By: gordon Category: Astronomy

I was up at Champlain Lookout in Gatineau Park Friday evening with my telescope to do some astrophotography. I was looking at Saturn and all of a sudden something very bright moved across the field of view from left to right (in the eyepiece). There are only two plausible explanations I can come up with…

  1. Satellite
  2. Meteor

Whatever it was, it’s definitely the most intriguing thing I’ve seen through a telescope.

Ring Nebula (M57)

Yesterday evening was a beautiful evening to be out with a telescope. I decided to go after the Ring Nebula (M57), which was visible high in the sky.

This is an extract from one of the images I captured. The rest are being stacked as we speak.

Andromeda galaxy (M31) – first attempt

September 10, 2017 @ 11:13 By: gordon Category: Astronomy, Photography

I headed out yesterday evening to see what I could see. One of the things visible in the sky last night was the Andromeda Galaxy (M31). I put my camera on the back of the telescope and took a number of images. After aligning the images and working on them in Photoshop, I have an image where you can start to see some of the structure in the galaxy.

There’s specialized software for processing astrophotographs. For this image, I used one to figure out the image offset between the 8 images that went into it and then used Photoshop to manually align them. Then I converted the layers into a smart object, stacked them and applied some curves, exposure, level, and brightness/contrast adjustments.

For a first attempt, I’m happy with the results. I want to explore some of the other astrophotography software out there to see what works best for me.

Totality

I headed to Glendo State Park in Wyoming today to watch the eclipse with some friends. Here’s a quick photo of totality…

Jupiter

I shot this with my Tamron SP 500mm lens earlier this evening. With a bit of noise reduction in Lightroom, you can make out 4 of the moons.

A few photos from the WGS-9 launch this evening

I arrived in Jupiter, Florida earlier today. This evening, there was a launch of a military communications satellite, known as WGS-9, from the Kennedy Space Center. My parents and I headed out onto the balcony in front of the place they’re renting to see if we could see it.

Happily, we could…

For those wondering about the technical details of the photos: Canon 70D, Tamron SP 500mm, 1/160s, f/8, ISO 12800.
