The Spindle Galaxy as seen by RCT


NGC5866 in the H_alpha filter

Some of you might have noticed this week that we have cleared some space in the queue to allow a couple of students to take data for their Astronomical Observational Techniques class.

Jason Leszczewicz, a Physics major at WKU, took this image of galaxy NGC 5866 for his project to determine the star formation rates of a sample of galaxies. This image is a raw 300s exposure taken in the H_alpha_continuum (6444A) filter.

NGC 5866 (also called the Spindle Galaxy or Messier 102) is a relatively bright lenticular or spiral galaxy in the constellation Draco. As clearly seen in this image, it’s most prominent feature is it’s edge-on dust disc.

It was so pretty I thought everyone should see it.

Let me know if you have any similarly pretty images taken with the RCT!



Pointing Error

Hi Folks,
It looks as if we were slightly off in our pointing for some observations last night resulting in acquire errors for some guided targets. Observers who did obtain data, can you let me know if you also saw a slight offset in your pointing. Any other comments about data quality you’d like to add?
