The Lagoon Nebula ( Messier 8, NGC 6523 ) in Sagittarius
The Lagoon Nebula ( Messier 8, NGC 6523 ) in the constellation Sagittarius - by Mike O'Day ( https://500px.com/mikeoday )
The Laboon Nebula ( M8 ) is visible to the naked eye under dark skies from most latitudes except the far north. Seemingly covering an area about three times that of the full Moon, M8 actually covers an area somewhat greater than 110 light years and is around 4300 light years from Earth in the Sagittarius-Carina spiral arm of the Milkyway galaxy.

re-processed 24 April 2016 to include the additional subs ( the first version only made use of the 23 x 240 sec ISO 200 subs ) and putting use the processing lessons I have learnt over the past year.
Canon 1100D astro-modified.
For sale, excellent condition (no marks on the body) very low shutter count under 4000. The IR cut filter has been removed for more response on red (spectrum) emission nebula. Comes with battery and charger, and cable to connect to computer.
Full computer control with software like APT, live view, 12 mega pixel, the camera also feels lighter than its previous model 1000D.

Attempt #2 at imaging Jupiter!
Attempt number 2 at processing Jupiter. Finding it incredibly frustrating trying to image with my current set up, so have invested in 'Making Every Photon Count' to help me decide what I should upgrade to!
Composite image of Jupiter and 3 of its Galilean moons
Canon 70d, 8" Dobsonian (prime focus and manually tracked)
1 x 30 sec video, stacked, for Jupiter
I attempted eyepiece projection, but couldn't achieve focus... no doubt I am doing something wrong, but couldn't work out what!
