Thread compatibility, focus extension, and focus must be checked for each combination. Accessories are sold separately.<\/p>\n<p>In astrophotography, a DayStar tilt adapter can help reduce Newton's rings. The results depend on the camera and the settings; see the <a href=\"https:\/\/www.daystarfilters.com\/interference-eliminator\/\" target=\"_blank\" rel=\"noopener\">Manufacturer's installation instructions<\/a> to choose the right adapter.<\/p>\n<h3>Do you have a project for your club or school?<\/h3>\n<p>DayStar has been developing solar equipment for over 50 years.
