M83 from Mt Kent

[peter_4059]

Spent Saturday and Sunday nights at Mt Kent trying to image galaxies but the wind, dew and poor polar alignment got in the way of capturing some really long exposures. Despite all that here's my latest attempt at M83 using the DSI and 10" newt. This is a stack of about 50 x 30 sec subs.

Hi Peter, a great looking image with the DSI, nice detail and the extensions of the spiral arms are well extended.

A fine effort, are you thinking of adding any colour to this image?

Cheers

That is a very nice image of M83 Peter. Lovely detail in the galaxy structure - well done!

Cheers

Cheers Ric and Dennis.

I had set out to do a colour image but ended up having a lot of trouble getting the images to stack in Envisage so settled for only the red. I will give tri-colour another try from home but don't expect to get the same result with all the light polution here.

Looking good Peter. You captured a lot of detail in the Galaxy.

What is the reason for 30 second subs? Did I miss something?

Matt,

I just go for the longest sub I can get away with given how accurate the alignment is, how much time I have etc. Meade recommend at least 50 subs stacked to get good signal to noise so the longer sub means longer total duration.
