Good ventilation to dissipate heat may cause subject movement if the subject is not heavy. If the subject is heat sensitive you can easily melt your project or make it turn brown, black or dead. I have experienced all of the above.

when looking through a 10x peak loup, i can see the grid of the ground glass (there is a fresnel attached) which somewhat blurs the image at 3:1.

A friend of me adviced me to create a setup where a plain glass is positioned (at the right location) which gives a bright image when looked throug a loup for focusing.
