Currently some products are out of stock due to COVID delays in manufacturing and supply chains. Unfortunately, we cannot predict delivery times and have many thousands of customers, which we cannot inform individually when a product is available. Therefore we have developed two automatic tools which we would like to ask you to use.
2nd "Notification Tool"
On the page of items that are currently not available, there is a field "Notify me when the product is available".
If you enter your email address there you will be informed as soon as the product is in stock.
Thanks for your understanding!

I have a fast newtonian Astrograph (F/3) and a moderately fast Refractor (F/4.5) Would the UNB f/2 filters proved acceptable transmission with the F/4.5? Can you provide a number for transmisison of the filter set for a F/4.5 telescope? Would you recommend the normal UNB filters instead?
For f/4.5 we can only recommend the regular ultra-narrowbands – the f/2 family will not work.
We will not speculate on possible transmission of f/2 filters when used at f/4.5, because any loss of s/n will be bad.
