Description

Revision C- December 2022:

Following up on the original upload 12 months ago, I have reshot this view of the sky. I will try and keep re-updating this in 12 month intervals as I hopefully get better at the hobby

This years photo still uses a Samyang 135mm. This time its twin Samyang 135/2 lens paired with twin Canon 6Ds, on a Skywatcher EQ6R. The integration is around 420x2 minute sub exposures, from my backyard. Total exposure therefore around 14hours.

Compared to the 2021 image, the equipment is a bit better, and the integration time much longer. The far worse sky conditions in my backyard compared with the darker skies in 2021 is a great equaliser though. 


Revision A- December 2021:

This image is a blend of images shoot at 135mm and 200mm around New Years Eve 2021.

It is approximately 3.5 hours of sub-exposures using a Tamron 70-200mm f2.8 A009 lens (at 200mm), and 1 hour of sub exposures using a Samyang 135mm f2.

The camera was a Fujifilm XT-1 full spectrum modified, on a Skywatcher Star Adventurer. Bortle 3/4 Skies

This was a first time using a tracker on Orion, and the first time using the XT-1 for astrophotography. Unfortunately, the XT-1 (purchased used) appears to have a slightly tilted sensor. As such, it has been retired from astrophotgraphy duties. It is now used exclusively for daytime infrared photography, which is not demanding on sensor orthogonality.

I'm not super happy with how this image turned out, but I think its important to publish as a yardstick for future attempts. At the end of this year, I'll definitely be trying again to shoot of this region. I'd like to get more total exposure time (weather permitting, by a factor of 4x) and cover a slightly wider field of view.
