Nice work Martin ..as always.
Make yourself a baffled dew tube you will find that the light next door will go away and also it eliminates stray light from stars, planes, even minimises the sky glow...look at Hubble...tube extended well past secondary and it is baffled...I have not got one on the 115 mm yet and I noticed last night a circle of light..oh no what the heck...mmm Jupiter..now if I had the "stray light inhibitor tube" I would not have had that light worrying me...now you notice Jupiter but you don't notice the stray light running around and finally hitting the sensor...the more you can do the better will be your contrast...if you don't want to go to the trouble of baffles at least try a roll of cardboard with sawdust paint ..make it two and a half feet...maybe two.
