M81 and M82


Recommended Posts

Hi every one, whilst I was waiting for m78 to get past the house, I thought I would have a quick go at

m81 and 82 with the  SW reducer Flattener, that gives a shorter focal length and slightly faster optics

on the f4 Quattro  brining it down to f3.6..

I normally struggle a bit with the optics on the Quattro at the best of times so I was a bit hesitant on using it.

The picture is a result of 48 minutes worth of subs a mixture of 500 second and 300 second subs.

A little noisy and the stars are not 100% especially going towards the corners but I don't think it is to bad,

I might be able to tune the Quattro a little more but inevitably the stars will never be as good as using  the correct flattener.

Software used :PI and DSS and PE
