Darks and bias frames

[Pankaj]

Hi all. I hv just finished imaging m 45 at 50 sec, iso 800 along with its darks at 50sec and iso 800 and bias frames at 1/4000, iso 800. After this I started session for m42 immediately. The capture settings of light frames is similar to previous session I.e. 50 sec, iso 800. Do I need to take the darks and biased frames again or can I use the ones I took for m45, since the temperature remains the same. Urgent advice needed

They will be fine if the temperature is the same. To be honest you should try using and not using the darks when you stack because the true chip temperature for each sub can still vary.

An interesting video just posted by Avocette. I am no expert so won't comment, but it was an interesting watch.
