My thought is that you are too magnified (slow scope plus small FOV of the LPI) that even if you did have the DSO centred it will be extereeeeemely faint.
Another point is, can get pull focus?
If you can focus on Saturn you should be OK.

Focal Length is 1400 mm and size is 150mm I am not sure about focal ratio. I could focus on Saturn with the EP all sizes that I have 20mm,12.5 and 9mm as well as using a 3x barlow
