NGC 3293 with modified Sony NEX-5 and 22" Dob

[alexch (Alex)]

Hi All,

SPSP was very enjoyable and on the way back we stopped at a dark site near Albury for some more imaging and observing.

The Gem cluster is my daughter's favourite and I wanted to image it for a while. The new modified (with UV-IR cutoff filter) Sony NEX-5 performed well.

The ServoCat driven Dob works best with objects at around 45 degrees altitude and I was able to get 92 good subs out of 150. Below is a very quick processing in DeepSkyStacker and curves adjustment in Photoshop. I am sure I will re-process this image when I get more time and get to know the modified sensor better.

NGC 3293: 22" SDM Dob, Sony NEX-5-A, 92x15sec ISO 3200.
Image scale: 23.2'x34.8'
I attached the small image and the full-size image is here:

Cheers,
Alex

Not bad for 15 sec subs through a dob with a non-DSLR camera!! Nice one!

Cheers, Marcus

PS: Congrats on your SPSP 1st place for your "3 Galaxies and Meteor Shower" shot!

The smaller size looks excellent, lovely colours and nice subtle hues.

Thanks, Doug. I can't wait to process the rest of the data I acquired during the three nights but will not be able to do that for about two weeks due to work commitments

Thanks Marcus!

The sensor in NEX-5 is the same they put in the DSLRs, it just does not have a mirror. I would rate Sony NEX series up there with latest APS-C DSLR cameras.

Thanks, Marc. The modified sensor delivers much better colours than before.
