Hi all, last night was the best night I have had for astro for many months, calm, cloud free and low humidity. I was keen to try out the UHCs filter I had puchased a few weeks ago. I have never used filters, and thought they were only for light polluted sky conditions. Well I was very impressed with the results. I took some images of the same area without the filter and there was no comparison. The contrast and extra colour this filter revealed in the Veil nebula has convinced me to use it more often than not.
This is only 4 x 5 minute exposures taken with Astro 40D at ISO 1600 and Takahashi 160mm Epsilon Astrograph F3.3 .
Stacked in DSS and processed in Photoshop.
