[1.25" Eyepiece] Used it one night for shooting the milky way, significant difference in brightness.

[1.25" Eyepiece] Baader makes some great lenses and filters, I have yet to be disappointed and this one is no different.

[1.25" Eyepiece] Bought this and its matching tx. They seem pretty good. You can select different definitions, FHD, HD, SD, and then can assign them to the 3 types, and allocate bit rates for each. Eg you can select HD, send that to SD and a bit rate of 800 and FHD to HD and a bit rate of 2000 etc. It then selects the resolution type, eg 720P. The only limitation I find a bit strange is that the full range of resolutions, are not available all the time. They vary what is available depending on the Hz, 50Hz or 60Hz of the incoming HDMI. I am using 60Hz, and this does not have 1080i, but if I was using 50Hz, then 1080i would be included.
60Hz has 480i, 480P, 720P, 1080P.
50Hz has 576i, 576P, 720P, 1080P, 1080i.
The other strange thing I notice is that if I select a bit rate of 800Kbps, and then monitor the link at the IP level, it seems to be using about 3.5Mbps.
However, for quality and ease of use, these seem to be great devices.

[1.25" Eyepiece] I bought this to see if it would help bring out some color and detail for my astrophotography. I have little light pollution in my area but it this thing really does what it's supposed to. I did some test shots with a colorchecker passport in regular daylight and the difference is definitely noticeable. There's a very clear boost in color and slight boost in contrast, what I mean is that they appear more clearly and saturated. It's magic! I might even start using this for some regular photography too! I have to use step-down adapters to fit these onto my lenses as I am not using it with a telescope (67mm, 58mm, 52mm). I just wish they made these in sizes native to DSLR/Mirrorless lenses! Highly recommend! Also if you are someone purchasing for a DSLR/Mirrorless camera, Get the 2 version of course, and you will need step-down/step-up adapters to 48mm. Even though 2 is not 48mm, that is the threads for this baader filter. I recommend the sensei filter adapters, cheap and very well made. In order to adapt some lens sizes down to 48mm, you might have to buy a couple adapters and stack them. I had to do this for my larger 67mm lenses. There will of course be vignetting when doing this, but its no big deal to me.

[1.25" Eyepiece] There is no better narrowband green filter for astronomical observations and photography. I have been observing since 1974 and this filter has turned my achromatic refractor into an apochromat. Viewing on the Moon cannot be sharper eliminating chromatic aberration by using one wavelength of color and then converting to black and white monochrome. Baader's reputation exceeds itself.

[1.25" Eyepiece] This is one of the most informative books I have seen on Astrophotography! Explained in detail everything you want to know and how to get those amazing,spectacular astrophotography shots you have been dreaming of but thought impossible or out of reach. Very clear and precise directions to the stars, galaxies,planets, and anything else you would want to look to the heavens to capture. Love this and I highly recommend this book to everyone interested in astrophotography!

[1.25" Eyepiece] Good filter

[1.25" Eyepiece] What can I say about an air filter. It appears to be quality made,

[1.25" Eyepiece] They work quite well; no halos or any undesirable behavior which I could notice as of now. They did require an increase in exposure time, but that's expected.

[1.25" Eyepiece] These units are ideal for instant connect up and they work. You can customise the bit rate and it keeps the video smooth. One TX can feed many RX.
