A Wide-Field View of Eastern Cassiopeia

Below is an image of Eastern Cassiopeia taken on a November evening with a thin cloud layer high in the sky, giving the sub-frames a light orange glow. After processing, I kind of like the effect it had on the stars. At the time though, I packed it in early because of the high clouds and the orange color in the subs….. if I had processed a few images right away, I would have taken several hours of imaging.

This is a 10-minute total exposure using a Canon 6D, Canon 100mm f/2.8L, iOptron ZEQ25 mount, 60-second subs at ISO 3200. How many deepsky objects can you find in this image? Scroll down for a labelled version of this image.

Andromeda and the Pinwheel Panorama

I’ve been working over the last several months in building a large panorama of the Northern Milky Way. I thought I would clip out a piece of the large panorama and see how it looks, this is a snip from the larger view showing the Andromeda Galaxy (M31, on the left) and the Pinwheel Galaxy (M33, on the right). If you look close at Andromeda you will also notice M110 and M32 elliptical galaxies nearby.

Imaging done in November/December 2015 using a Canon 6D and Canon 100mm lens. These were mounted on an iOptron ZEQ25 mount, images were 60 seconds each x 15 images. Each process TIF file was then stitched together using Microsoft Image Composer. I’ll share the larger pano when I am farther along.

My wide-field setup for this image (just replace the 400mm lens with a 100mm).

Tiffen Star Point Filter and Venus

Ran across this Tiffen 67mm 4-Point Star Filter (2mm) and thought I would try it out on my 100mm lens. Here is a test shot from this morning using Venus and some trees in my backyard. Looking forward to trying this filter out on a panorama image.
