I know that going to a dark site would get me better results, but it is what it is...

Imaging from my city backyard, I wonder what techniques you guys use to get better results at shooting galaxies.

It's the galaxy season, isn't it? Bye-bye narrow band and multi-band filters, welcome back my old and trusty friend - UV/IR cut filter.

This is a 3 hour integration of 2 min subs, shot using a 6" RC scope with a 0.67x telecompressor.

Nikon D5300 full spectrum + UV/IR cut filter.

Looks fantastic! Will have to give this target a try once I have my 6SE ready.

Very nice capture!

 

... welcome back my old and trusty friend - UV/IR cut filter.

Good, I just picked up a Optolong UV-IR  cut filter to try and get some spirals.

 

BTW, you live in one my three favorite cities: Vancouver, BC, Hong Kong, and my birthplace, San Francisco. I would love to get another visit to Vancouver.

Very nice <3 . And with a telescope of moderate size.

I see a lot of cool images at CN all the time and the digital evolution in astronomy is amazing since I was shooting old Kodak film like 103A-F, So115, Echtachrome etc. A lot has happend! :)..

The thing that all the time itches my mind when I see the way its done nowadays is all the 'Subs' taken. It often gives nice results and very much less startrailing than it used to 'analog days'. But,-say 100 subs of each 30 secs or more. And sometimes subs taken with days between them.

What 'bothers' me is : What happends in between the subs? Was there a bright flash from a spinning neutronstar or a sudden reflection from a fast asteroid? What is lost in a picture the moment the camera shutter is off. Thats what Im thinking :)

Most excellent!

 

I do all of my imaging from my Bortle 8 backyard and for some reason we have run into a months long stream of poor transparency on top of sky glow. We used to get lensed SQM reading on the order of 18.6, but 18.3 now seems to be the new normal. As you say, it is what it is. Not every image can be a Hubble look-a-like, but it's still amazing what we can see with our cameras. A couple of nights ago I NGC-hopped the Virgo cluster with my 12" and most were no-shows and the rest were just the soft glow of their cores. I luvs my cameras!

 

Nicely done!

Thank you. I use exactly the same Optolong filter.

Welcome to Vancouver, any time after all the craziness settles down a bit :)

I sometimes ask myself the same question. We are not capturing the "moment" and I always see other stuff in the images, like meteors. Those single subs can sometimes be great images on their own.

Thank you! We also have average or below average seeing here almost all the time. Living between the ocean and the mountains has its disadvantages. I actually have the Virgo Cluster on my to-do list and hope I will have time to image it this year.

For anyone who is wondering what a single sub looks like, here it is.

Straight from the camera, unstretched and uncropped.
