Solomark 1.25 Inch UV IR Cut Block Filter Infra Red Filter CCD Camera Interference Uv Filter

This filter is great for its price, it helps with a lot of environmental factors like distortion caused by the telescope and helps with dew on your lens, but it adds a weird round lens distortion depending on the angle, the first image is with the filter and the second is without.

I love astronomy, but my checkbook often finds itself abused by my favorite hobby. I am always looking for that gadget that will do what the high end stuff does with at a much lower cost. More often than not, I end up disappointed. Not this time! This filter is excellent. I live is an area with some light pollution. I can still see a faint glow from the Milky Way on really,really good nights. The major stars in most every constellation are visible almost every clear night, so I am not looking for a light pollution slayer. I wanted to boost contrast... And boost contrast it does. The sky becomes much blacker and the nebulas become much brighter. It is amazing! From my house, I can not see any nebulosity in the eagle nebula. I put this filter on, and the nebulosity became immediately evident. The lagoon nebula is usually just a streak of nebulosity around the two stars next to the cluster. With this filter it became much larger with the dark streak dividing it popping right out. The triffid is usually a challenge, it was easy to spot with this filter. He blinking planetary became very bright and easy to see. It really does work. It will do nothing for galaxies. I tried but it just makes them dimmer. I didn't bother with globular clusters, expecting the same results, but if you like finding nebulas, this is the filter to get.

Blocks uv and ir as advertised but the threads don't screw smoothly into other filters or the nose piece.

I'm very glad I picked up this IR/UV cut filter. While I have yet to use it with my converted webcam against the night sky, I used it during a daylight test against some foliage off in the distance. While the leaves are normally washed out to almost gray color when the webcam is used in one of my telescopes, the addition of the IR/UV allowed the greenery to should up as the vibrant green we see with our eyes. Hopefully soon I'll be able to take it out on a clear night.I did notice it look a bit of force to get the filter to twist when I was attaching it to my webcam adapter, being careful not to cross the threads. It cleared up after a few removals, so I'm going to say it's not the filter's fault but the adapter having too thick of a coating over the threads. All in all, I feel this is a wonderful filter for the price and I'm incredibly happy with my purchase.

Great filter for the cost. Used with my full spectrum modified nikon d5300. This was taken with my sw evostar 80 ed, eq6r pro, 4x5 min subs with a not quite full moon.

I enjoy having this lense with my extensive collection. The lens helps reduce light pollution and moon viewing is slightly better. The lens isn't amazing but, works, I was able to see Orion's Nebula on the constellation's belt. The lens increases visibility of hard to see objects every so slightly. I enjoy using it, not as impressive as I originally thought but, not disappointed either. I also viewed Andromeda's Galaxy with the help of the lens.

For $40 I didn't know what to expect. These can come in at much higher price. I was pleasantly surprised. You will be able to see more detail in some nebulas. Obviously it does not eliminate light pollution, but it does reduce its impact and nebulas will be more extensive and stand out from the background. I cannot compare it to more expensive models, but it works. The difference might be subtle for those new to the hobby, but you'll appreciate the difference as you gain experience.

Does a good job of cutting out light pollution. The sky is much more black than without it. However it does cause a halo. If you turn down the exposure it does go away or weakens up enough not to notice. For the price I can't complain too much. Attached a picture with the exposure turned up to show the halo and one turned down.

Amazing for those who remove the IR cut filter from a color CCD camera in order to get better H-alpha sensitivity. When you want "true colors" from the camera at day, on with this filter. B/W cameras without IR cut will not be as sharp due to the wide bandwidth of the light, the sensitivity has a cost. With this filter - you can have both.

Adds a lot more contrast to camera astro images. Not sure if it is great, as my experience is limited, but can see a large difference in 180 second exposures, far less washed out.

Arrived on time, fits perfectly and definitely makes a difference.
