Baader Solar Filter – the Standard
Mounted Filters with Baader AstroSolar Safety Film OD 5.0
After 15 years of offering AstroSolar film sheets as a DIY product, this system of Baader Solar Filters™ is designed to retain the true optical quality of the diffraction-limited AstroSolar Safety Film.
Baader Solar Filters provide a professional and secure solution to observe and image the Sun using AstroSolar® Safety Film OD 5.0. Many ready-made filters stretch the filter material like a drumhead to make it look like a piece of glass – this reduces image quality, rendering the film useless for high-magnification work. AstroSolar must be mounted entirely stress-free to perform like a high-precision planeoptical window. It sounds like a contradiction with the traditional perception of quality, but AstroSolar must show slight ripples!
- Safe for solar observation and photography with all high-end telescopes and extreme tele-lenses. Suitable for high magnifications and detailed observation of individual sunspots
- AstroSolar Safety Film OD 5.0, mounted stress-free in temperature-compensated cell
- No astigmatism during winter observation or with temperature changes in summer
Scope of supply: Each ASTF Filter with apertures from 80 to 180mm (200 – 280mm not yet available) includes two sets of centring bolts in 38mm length. Three bolts with 10mm diameter and three with 20mm diameter, adjustable to the tube diameter of your telescope or dew cap. In addition, they include three safety straps with glue pads and three rubber plugs to cover the holes that are not used—as well as mounting instructions.

Baader ASTF-140 OD5.0 Solar Filter 17 June 2024 | Steve
Product is well made and extremely easy to assemble & fit. It is light in weight so does not stress the front hood when extended.
I have only been able to use it twice so far (when the weather conditions we suitable ie late morning and good seeing).
Results were above expectation for white light imaging at F/7 & F/14.
I coupled this item with a Baader Continuum filter and that did improve the contrast and detail even more (again ... as expected.
This is a very worthwhile product to get into Solar imaging with your existing equipment without out going down the dedicated options ... Lunt etc, That will come much later.
Thanks again FLO for your advice and confirming fitting dimensions along with the quick delivery.
