Hi everyone,
Bit of a newbie at this, but took a few photos with the DSLR.
I have a canon 350D with Ha filter and Canon 450D (no mods). I have attached 4 photos (not stacked). Each labelled in file name.
Reasonably chufed I actually got some images at all to be honest and the wife was impressed. I know they will never win any prizes but it feels like a good start!
I actually took most photos through my LX200 8". A couple of questions.
1) How do you set up the DSLR so it has the best focus? I was trying to use the viewfinder and had nothing else. I was told some cameras show it on the back screen. Not sure if these do have an ability to show on screen. i know my photos seem a little out of focus.
2) What is the best ISO range for taking deep sky objects? I was sitting at ISO1600 (think I am recalling correctly!). I took 30 sec, 1 minute and 90 second exposures. Found that over 2 minutes had too much noise in brightness for Orion.
3) Is there a preferred exposure time for DSOs? I understand stacking is better but would like to know length of exposure.
4) Also when accumulating exposures of an object is there a good range or magic number to take for stacking (particularly in these examples)?
Thank you in advance for your help.
