Stacked image of i-have-no-clue-which-bit-of-sky...
« on: 15:15:13, 28 December, 2016 »
Hi!

Glad to find a forum where I can (hopefully) improve my astro photos.

Started a few days ago, using a Canon EOS 100D with the 18-55mm standard with a focal length of 18mm and f3.5 and 15 sec exposures and 800ISO.

Just looking to get some nice starry images to start with (was going to go for Betelgeuse and Orion but blocked by the treeline!!!)

Here's the photo I made yesterday with DSS. About 5mins of exposure and a few dark frames.

Quite underwhelming. Anyone got any ideas on how to improve? I cant increase the exposure without getting star trails and I'm not about to invest in a tracker...


Thanks!!!

Really you need some sort of tracker / mount for the longer exposures.     Have you tried star trails ?  pointing the lens as the northstar and taking lots and lots of 1-3 mins exposures,  They can be very attractive if you can get a good foreground object like a old tree or church steeple

Thanks, I'll give that a try soon. Currently waiting for DSS to stack my photos of orion... Hopefully they'll turn out okay!

With regards to your first image posting of " I have no clue which bit of sky"..... You have the constellation of Auriga to the upper right of frame with Gemini at lower right.
I do some widefield imaging using the Canon 1100d which will ramp ISO upto 6400. Unsure offhand what your 100d will got to, but as a first thought, experiment with some high end ISO shots at your short exposure times. Images may get slightly grainy but stacking will help here.
Best wishes,
Les
