Celestron Solar Filters are made with Baader Astro Solar Safety Film, and yield bright, sharp images high in contrast.
Astro Solar Safety Film is clear and homogenous, attaining the optical performance of high quality plane-parallel glass filters, and is diffraction-limited! The double-sided metal coatings have uniform density and good color balance across the entire field to ensure edge-to-edge sharp imagery.
When using the solar filter, the Sun appears in its real color neutral white-not blue or orange-and the sky adjacent to the solar limb is jet black. You'll see detail in sunspots, bright faculae near the limb and the mottled areas known as granules. The Sun's constant changes keep observing interesting and fun, even with small-apertures scopes.
The film is completely safe and durable, not breaking like glass if dropped. It transmits 1/100,000th of visible light (0.001%) while reflecting 99.999% of unwanted light.
Adding a #21 orange color filter on your eyepiece gives truer solar color renditions.

Comments about Celestron Solar Filter for use with the C102, NexStar 102 SLT & Other Telescopes:
Works as advertised. I bought this shortly after I purchased my 1st telescope, and the images are stunning. I've been able to see sunspots and some coronal mass ejections. I would highly recommend this product; particularly with the onset of a new solar cycle this year.

Comments about Celestron Solar Filter for use with the C102, NexStar 102 SLT & Other Telescopes:
I can't really give this an accurate rating because it doesn't fit the telescope it was purchased for. We have a Nexstar 4 SE and this website shows this filter as an accessory for that telescope but it does not fit it. Be careful to check for yourself rather than to rely on B&H's suggestions for accessories for your equipment.
Now I have to pay a 15% restocking fee and return shipping to return an item that I bought as a gift for my husband. I suppose I should have opened the gift first and then given it to my husband but I believed what I read here on this site. I have spent a lot of money here and am very disappointed that they will not make good on this item to make me a happy customer when the whole situation is due to their inaccuracy.
