I've had the ' objective ' lens off the main tube ..... cleaned both sides with
Bintel UHTC cleaning solution .. I removed ' dry swirling ' marks from the front of the Lens and cleaned the rear from general dust using a ' blower ' .
These ' spider trails ' remain and show they are between the ' glass elements '
Both the Outer and Rear ' faces ' of the Lens are clean and free from any dust or smudges ..... the ' spider filaments ' remain in between the glass... you can't get to it.
