CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!

M8 Lagoon Neb

Post by Astrosiao »

Hi All,

Following the horrible weather we have been having (and probably will continue to have), last evening was reasonably clear.

So, together with buddy cknjj, went out for a spot of late night imaging.

I have not been able to drift align so far, but managed to last night, its actually not too difficult.

So here is the result:

Scope: ES 127 APO
Mount: CG-5
Canon 5D M1
Non guided.
15 lights
2 darks (i actually forgot to take some in the excitement, these were done when i reached home)

Thanks.

Hi,
Nice... you should have taken more lights. What setting are you using??

Thanks for sharing.

Have a nice day.

Hi Weixing,

Thanks.
Each shot was only 30 secs at iso1000.

Could not manage longer exposures without trailing.

Also should add in a UHC filter.

had fun doing it though.

Did another round of imaging on friday.

Combined total 34 lights over 2 nights to yield this.

I think I have reached the limits of my scope/mount setup.

time to upgrade the mount...

Also, perhaps try some guiding.

Hi,
Is your CG-5 a GOTO mount? If you can't go "long", go "many"... I mean took lots of sub frames... basically use hard disk space to "achieve" longer exposure. Although many sub frames of shorter exposure can't really replace longer exposure, but it'll still make your image look better.

Also, how many dark did you use? Try to use more dark frames... I usually use 25 dark frames.

Happy shooting and have a nice day.

Hi Weixing,

1) I wanted to capture more lights but the conditions started getting worse. Anyway, I achieved somewhat my objective that evening which was to try and get polar aligned by drift method. Almost there...

2) I used 5 dark frames here.

Is there a relation on number of lights vs flats/bias vs darks?

Thanks.

Nice work! Keep it up!
8 to 10 darks will be good enough, same goes to flats and bias. Can do with more, but there will be diminishing returns. :P
