Default Additional 60 Minutes of exposure on M100

Again with DSI and LX90 @ F/5

30 minutes of colour and 30 mins of mono have been added to this image:

The result (now 84 Mins) is:

Most of the battle is filtering the light polution from the images. The
signal to noise ratio is pretty poor and strangely wasn't really worth doing
in Mono (probably mixes the color of the Light Polution into the now single
plane?). I'll keep adding to it if the weather permits and perhaps with a
few hours exposure the image should show both less noise and more signal.

Also managed to get in M91 which shows the faint bar structure of the Galaxy
but alas; also needs about another hour or so before bragging about it.
