Had a go at sveral objects last night to check out several procedures. One was a new polar alignment method and to see if a 102mm achro scope was any good for imaging with a new Lumicon focal reducer.
All photos are a stack of 50 x 10 second subs with dark frames removed. Then into PS for levels adjustment, except for M42 which had a slight unsharp mask applied. NGC 4945 was taken sans the FR.
Was surprised at how some of these turned out but as far as I'm concerned Ill stick to the camera as a guiding camera. It would be interesting to see how deep it can go at a dark site.
promising photos, did you use an IR blocking filter? Why not try taking 2-300 pics and see the difference.You might be suprised.To reduce the noise you will need to take 2-300 dark frames as well.

IR filter used on all shots except that of ngc495. I removed it without thinking when I removed the focal reducer. I was interested to see if a cheap achromat could be useful for deepsky work with the watec 120N+. Will have to go deeper but I figure I'm wasting my time in a light poluted area with such short exposures (10 sec).
