OPT was the only provider made it available when I needed and I really appreciate their service. The product deserves its price very well because of the following reasons: 1- It is heavy enough to shield against wind and does not cause any sailing effect 2- It is not too heavy and it allows smooth operation of the mount controls and eyepiece changes 3- It is large enough to cover the front of the scope and shield against sunshine and heat 4- It covers your head and back of your head providing darkness that significantly increases visual contrast and quality 5- Insulation of observer increases comfort and results in extended observation time Do not waste your time with any DIY projects. This is the ultimate solution.
This is a solar observing hood to block light and increase contrast of your view .. not a telescope cover. As a large format film photographer I have dark cloths for my view cameras that do the same thing but are much lighter, this is too heavy and shakes my view with my TV-85 if I don’t hold my breath. Not OPT’s fault, OPT’s shipping was lightning fast and the item well packed and factory sealed.
Wow had it in 2 days.
I really like the Velcro closure on the front as it accommodates any size tube. It would be nice to have more Velcro on the bottom to block reflected light from the bottom for better contrast.
Arrived in good order very efficiently.
