M88.
Taken using a ten inch F/.8 reflector, a vixen atlux mount PHD auto guiding, An Atik 383L mono CCD camera and a set of Astronomik RGB filters.
The data was taken on two separate evenings under poor sky conditions with intermittent cloud cover. I was only able to capture 60 second sub frames in the breaks between the clouds.
The total exposure time was ten minutes using a red filter, twelve minutes using a blue filter and fifteen minutes using a green filter.
M99.
Taken using a ten inch F/4.8 reflector, a Vixen Atlux mount, PHD auto guiding, an Atik 383L mono CCD camera and a set of Astronomik RGB filters.
I captured five minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image.
The total exposure time was 30 minutes for each filter.
