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).
