Some Late Summer DSO's with a DSLR

[Roy Foreman]

My cooled astro camera is playing up, so when a rare clear night occurred recently I reverted to imaging with my trusty Nikon D810a - an amazing camera that is so much more than just a stock DSLR with a modified filter.

Image details are as follows :-

 

North America Nebula

Stella Mira 90 EDT at f/4.8 - 20 x 30 sec at ISO 6400 plus IDAS NB1 Tri Band Filter

 

Dumbell Nebula

16" Reflector at F/4.5 - 20 x 45 sec at ISO 1600, no filters

 

Ring Nebula

16" Reflector at F/4.5 - 20 x 30 sec at ISO 1600, no filters

 

For what its worth, I've imaged all of these objects with my ASI 6200 MC with total exposure times four times longer than these, but results hardly any better. Can't explain why, but food for thought.

Hope these are of interest, especially to those who are imaging with a DSLR.

Thank you Peter. Having just posted these I now need to figure out why the colour balance looks different to the originals !!

have you checked the colour profile is srgb for the web? TBH I have found images do vary from website to website.

I will check that out. Thanks for that Peter
