Thank you.  Is that a protostar?

Binged it - a galaxy with a central bulge.  Very nice shot!

Hi guys this is alex with another noob question...I hope you enjoy this one...
Milky way season has started so I had my first shooting with a tracker.It went great exept that
as the galaxy rotated, light polution low at the horizon crept in from the bottom right.The galaxy
has the framing I wanted but the light polution is tilted.Any solutions to that?Post or while shooting?
Here's the image

nice shot, light pollution is par for the course..  you can get a clip in filter for the DSLR  such as

http://www.rothervalleyoptics.co.uk/astronomik-cls-ccd-deep-sky-light-pollution-filter-canon-eos-clip-fit.html

(not connection, just googled clip in light polliution filters, I knew they were out there)

There are various programs that do a good job removing things like this.  I still use IRIS which is a nightmare to learn.  I've tried photoshop but if you care about reality in your astro shots (I do) then it really feels like cheating (IRIS is good at getting a real data, rather than pretty pictures).  Pixinsight is very good and when my scope gets back up and running will be what I migrate to for the pretty stuff.

thanks for taking the time to reply rfdesigner
unfortunately I can not use the clip on filters as they are not ef-s compatible and my lenses are all ef-s.The image I posted is a not the final but a quick stretch to show the problem and it will be used as a background for a composite.To be honest I don't mind the LP near the horizon for landscape astro stuff but my problem is the tilt

Yet another 'clearly hacked into the Hubble feed' shot.  Thank you for showing the enormity and beauty of the universe.
