Polarizer & Neutral Density

Unfortunately we do only offer the items you find on our website

Thanks for your kind words. We can confirm that AstroSolar Safety Film (OD 5.0) in FRONT of your optics is suitable of protecting your instruments and eyes. No need for an additional IR-filter. Please also check out www.astrosolar.com for more informational pages as well as FAQs.

We have not tried this combination but the U filter is very dark wich lead to very long exposure times even with ideal cameras. Furthermore the camera you mention has a colour sensor with bad UV sensitivity. Therefore we doubt that you will create nice images of the Venus clouds with this combination.

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:
1st Newsletter:
If you enter your email address here, you will receive a monthly newsletter with a lot of information about our products and new releases
https://www.baader-planetarium.com/en/newsletter/
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.
