Received the secondary heater for the RC today. Installed as per instruction and gave it a rip tonight to see what its like. It certainly keeps the dew off but the fit isnt so good and now my star shapes are horrendous. Examples are a 10 min shot from a while ago and varying length shots tonight. The original shot has nice round stars but tonights all have weird flaring, I believe it is because the outer edge of the secondary heater slightly protrudes into the light path. Not sure if I can trim it so there is no protrusion or not. These pics have only had a stretch. Any suggestions appreciated, especially from those that have added the secondary heater to their RC's in the past.
