Solomark Webcam Adapter for Telescope 1.25inch Thread(with Good Paint)- Good for Taking Videos and Capture of Moon and Planets

This was advertised somewhere in an astronomy site as fitting most cheap webcams for use in an astronomical telescope. Unfortunately, it seems that most webcams being sold today no longer have the compatible lens screw thread, as they've gone to small fixed lenses mounted directly on the camera circuit board, and mounted in a case that's more stylish than practical. I was able to fit this on a Logitech C270 by doing some minor surgery, but it is not a simple screw-on process. If you want to put a webcam on a telescope, I've since learned that there are apparently now some cheap Chinese ones specifically designed to slide into a 1-1/4" eyepiece holder--costing under $30. This price range will give you a lunar or planetary image--not deep space objects (stars, nebula).

This is a well made device with clean threads and an internal graduated conical light baffling surface. This is an excellent way to mount a 'bullet' camera to your telescope. A standard 'bullet' camera is designed to produce a correct left to right and up to down image with a 'simple' lens like the objective lens of your telescope. I used my old UNITRON 114 Refractor Telescope with a 900 mm focal length 60 mm diameter objective lens with this attachment and a color CCD bullet camera [0.5 LUX sensitivity] and was able to read the fine print [about 1/8" tall font] and dials on the gas meter of a neighbors house at about 150 feet away on my large screen TV without using any other lenses or optics. I assume that it will work well with a Newtonian reflector type telescope except that the diagonal mirror may reverse the image. You can rotate this adapter with the CCD camera attached for a correct up to down image in either case. The 'bullet' camera is nice since its output signal can go directly to your TV via the RCA video jack - no other electronics or computer are required. Note that some black and white bullet cameras have exceptional light sensitivity at a detection level of 0.05 LUX or better. For less than $100 you can get these bullet cameras that will allow you to see in the dark by themselves and to see very faint luminous objects with your telescope without having to buy overpriced CCD cameras made by telescope companies. Remember that these bullet cameras are really 'live' video cameras without frame capture. If you want to save images you can record them off your TV by photographic means [digital or analog film] or use video software to save and edit them - you can also capture them with computer software - I prefer the simple approach of having a 'live' view for daytime spotting of big ships far out on the water and nighttime viewing of astronomical objects for other to enjoy on a big screen TV indoors or outdoors withe a small color monitor with RCA jack inputs. You can also record these images with an old VCR is you want to go 'retro' analog!

This adaptor is frequently purchased with the Logitech C270 webcam. I've seen several online recommendations for this combination. The threads are not the right size. They are not even close! I found a YouTube video offering a workaround: Drill out the hole in the webcam cover to fit the adaptor threads. I tried that, and it fits, BUT that moves the sensor too far from the focal point, so it's impossible to focus and image on the sensor. A great adaptor for whatever webcams it fits, but completely useless for the C270.

I used this with a 1/3" CCD color board video camera with a Sony chip. I unscrewed the lens from the board camera and the webcam adapter screwed in perfectly. I attached it to my Nexstar 6 with the 1.25" eyepiece adapter and it worked. I did get some reflected rings of light. I'm not sure where they were coming from. It seams to be a well made adapter.

The product itself was great, it did not fit the webcam. I had to drill out the case of the webcam and use CA glue to hold it in place.

Works like it says it does used it for astro photograpy the thread did not fit the cam amazon suggested on frequently baught together though i had to crazy glue it the 720 cam suggested has a smaller thread then 12m amazon should suggest a cam that fits the 12m thread.

Works fine, solidly made and gives me more options for my scopes. I recommend using a small and light webcam.

Fit my Philips toUcam PRO II webcam like a glove. No negative that I could find.
