Comparing the Sky-Watcher 190MN Pro and Altair Wave 115ED with 0.79x Reducer/Flattener
A rare combination of clear skies, stable atmospherics and no moon last night finally provided me with an opportunity to fully test the potential of the Altair Wave 115 ED Triplet Refractor, combined with the Planostar 0.79x Reducer/Flattener - and boy was it worth the wait!
I wanted to compare the results to my previous scope - the extremely capable Sky-Watcher Explorer 190MN Pro Mak-Newtonian Astrograph. So I chose one of my all-time favourite subjects - M42, the Great Orion Nebula and Running Man. The image I captured using my 190MN was the first of my own astro-photos that made me go wow! The image comprised of 10 x 300s, 10 x 200s and 25 x 45s exposures, captured and stacked using Nebulosity 3 and processed using Photoshop CS6. The final result is now framed and has pride of place on the wall above my desk. I was convinced it was going to be hard to beat.

In an attempt to compensate for the smaller aperture and slightly slower Focal Ratio, I increased the length of the exposures to allow as much light to reach the camera's sensor as possible. The final image, which you can see below, is the result of 14 x 600s and 15 x 30s exposures, captured and stacked using Nebulosity 4 and processed using Photoshop CS6. Some may say this is an unfair comparison, but all I wanted to do was see if the Altair Wave 115ED was capable of achieving similar results to the Sky-Watcher Explorer 190MN Pro. The answer is yes - definitely! But that is my opinion - let me know what you think.
