Well it seems my Pleiades shot from last Sunday didn't get to remain my favourite Astro effort for very long. I took this last night, The Andromeda galaxy and two of it's satelite galaxies:




12 stacked 1 minute exposures at 300mm F2.8 and ISO 800.

The polar alignment could have been better, I hope to try again soon and get more shots with a longer exposure time, especially since as of today I have a long enough counterweight bar to ballance the mounting properly! (I was having to adjust the motor speed every 5 minutes or so last night. Man this Tamron is heavy!)

Astronomy, what an interesting and gripping discipline!

Your images really are impressive. I like it very much. Like Clarky, I am interested in know more about astronomic photographing.

Congratulations Mongoose, you did an excellent work. Thanks for share so spectacular images. And of course, awaiting for the next Astro photo...




Best regards.

And only a 300mm lens! Very impressed. Unfortunately here I get way too much light pollution

Thanks everyone, very kind. Perhaps I'll post a summary of what I use and how at some point.

Believe it or not, Andromeda is huge. It is several times the size of the full moon, hence the reason you can use a relatively short lens (the above is cropped, but not by as much as you might think, full size ~2400x1400). Only the core is bright enough to be naked eye visible, so without a telescope it doesn't look much bigger than a star, but a longish exposure with a fast lens proves otherwise.

I love astro photography, nature does the composition for you
