First light Star Adventurer 2i and LMC

[Marko of Oz (Mark)]

Polar alignment could have been better and the focus was off a bit I think and maybe the iso was a bit high? but I like it.

40 x 2 min exposures
250mm F5.6 canon kit lens
800 iso

Looks pretty impressive. Great light effect and somewhat eerie..

Good job Mark, tracking fine, focus fine, and ISO ideal. All DSLRs have an
ISO sweet spot where the two types of noise intersect on a graph. My 600D
is 800, so I imagine your 700D will be the same. My 1100D was 1600.

Mark,

Nice image I like it as well.

Might try a similar set up myself for multiple
Images for a stacking trial.

Thanks.
Will stacking with Darks and or Bias frames improve this kind of shot or is it a case of try and see?

cheers

Hi Mark, you have an advantage living in Tassie[ I used to live in Rosebery],
with its generally moderate to cool temperatures. I have found that if the
ambient temp when imaging widefields is below 10 deg, darks confer no significant benefit if you take at least 20-30 lights, but the benefit rapidly increases as the temp rises into the teens. I have found that if you have a good dark site, flats are of limited value.
If you take darks at the same ISO and ambient temp as the lights, then biases are superfluous as darks contain bias information.

Thanks for the info Raymo.
