Have a look at my AP's Ive posted here . I use what I have which is an EPM-2 Olympus 4/3. Its a smaller field , thats for sure however I have been able to capture some well known Obs with a different look to the wide fields typically with each sub between 2 and 5 seconds. Granted my primary is 20"
Give it a shot and see what comes. Cheers Zubenel.
