Description

Wanted to find out how the 8" RASA does with galaxies and what better to image than the Markarian's Chain to take advantage of the wider field. The result is so la la, luminance alone is of course not the final answer, a color camera would be better. I will revive my Altair 183C for the next try, smaller field, but it will be in color. Another BIG problem is that I will need flat files (did not need those with the narrow band filters!), and I am not quite sure how to obtain them with the camera in the front of the scope. I will try the dusk/dawn method, maybe this will be already good enough. The image here was severely processed to get rid of all the gradients. A closer look at the galaxies also reveals that the RASA is not necessarily the best scope for these targets.

Description: Added a few Hα and OIII data to the existing Lum data. Gives at least a little taste of color.
