Boxing Day Night - fun in Mono


I took full advantage of the clear night on the 26th of December and managed to capture 3 deepsky objects - an unheard of feat at Welford Observatory :-)

The first result was from the Wizard Nebula discussed in my previous post


As discussed in that post I was less than impressed with the results. Good guidance from Stargazer's Lounge forum advised that I need a lot more data on this to get good results.

The other two objects I imaged were much more rewarding.

This is the California Nebula. I've always enjoyed imaging this object whereas most imagers I talk to say they don't like it. I love the billowing nebulosity caused by the star Menkib exciting the H-beta line.




The shot above consists of 24x5min subs fully calibrated and processed in PixInsight with MaskedStretch, a bit of CurvesTransformation and AtrouWavesTransformation for noise reduction. I'll be capturing even more data on this in the month to come so this is really a work in progress.

Finally I managed to grab 14x5min Ha subs on the Horsehead and Flame Nebulae in Orion. 


Fully calibrated and processed in PixInsight with HistogramTransformation, a bit of CurvesTransformation and AtrouWavesTransformation for noise reduction. 

Hanging off the left most star in Orions belt this collection of nebulosity has fascinated me since I started imaging in 2010. I was surprised at the results with such a small number of subs - looking forward to capturing more soon.
