Attempt at M42 after finally figuring it all out

Finally getting my setup all working correctly and in order i figured i share this single shot i took of M42.

Spent most of the night experimenting and learning my new setup, but now i am confident i can do it again all time every time.

Currently 4 min (slight drift), ISO 800.

Next goal is to image at 5 min without drift at iso 400 and 800 (to capture the dimer stuff) then stack.

Wish me luck.

Nice shot. You will be amazed with how much of the faint data you can actually pull out even with 4 minute subs. The trick is to take _lots_ of them to try and bring the signal above the noise.

You also have some kind of reflection at the top of the image.

Nice first shot! What processing sw do you have? Take a few sec shots for the core and the longer ones for the neb. If you use PS, here's a good tutorial:

M42 is a hard one to process due to its high dynamic range. Why not try on an easier object? I'm sure someone will suggest a good one. Have a look here:

Onwards and upwards!

Glad you like!

Don't go for emission nebs as your camera's unmodded. Sorry if you already knew that! :grin:

Hehehe i been trying to get that browser added to the useful links page for months now http://stargazerslounge.com/topic/220950-deep-space-object-online-browser/ with no luck :)

Otherwise thanks guys.

Using PS, trying to decide on Nebulosity or DSS for stacking. Still tweaking my PA as i always pack up every night (can't setup pier yet), so that is biggest bane.
