Objects In The Rear View Mirror Jurassic Park

These radios are amazing. Installed in my Jeep above my rear view mirror and I am stoked about it. It’s small enough to not be in the way but is great for communicating with fellow Jeep’s. I used the ghost antenna so that it didn’t get wiped out by limbs on the trail. I’m thinking of purchasing the 6db antenna to help increase my range. I feel you can’t go wrong with this radio! Will be purchasing another for my sons Jeep.

I have wanted a telescope since middle school, but procrastinated for over 60 years. Now I have a Sky-Watcher 4 Maksutov and life is good. This telescope is the largest size which will work with an iOptron SkyGuider mount, and altogether is portable enough to take out on a whim, or travel by air. The Sky-Watcher is made very well. The construction is solid but not too heavy. The optics are entirely enclosed, except for the opening for an eyepiece or camera. Focusing is by a small knob which moves the primary mirror. There is little or no evidence of wobble in the focusing process. The kit comes with a finder (red dot), star diagonal (mirror), and two eye pieces, 25 mm (52x) and 10 mm (130x), both reasonably good quality Ploessl lenses. The red dot finder (like a gunsight) makes it easy to find objects suitable for the magnification, and is simple to align on a bright object (e.g., Sirius or the moon). With the addition of an inexpensive camera adapter and T-mount, the Sky-Watcher becomes a 1300 mm lens, perfect fo sharing the moon and most Messier objects with friends. The FOV with a FF camera is about 1.2 arc-degrees. A 4 aperture can be used to view objects as dim as Magnitude 12 or 13. A larger scope and eyepiece (2 v 1.25) would be better for viewing or astrophotography, but much heavier and starting at 4x the cost (including mount). Im extremely happy for now, and its something to share with my grandchildren. Best of all, it arrived in time for the Blood Wolf Super Moon eclipse on 1-20-19.

In the mid-1980s I bought a Nikon 7.5mm f5.6 circular fisheye. Being an older design (1966) its rear elements protruded into the mirror box. Fortunately my F3 had a hard physical mirror lockup. The external viewfinder for this lens attached to the camera on the original Nikon F/F2’s proprietary flash shoe. I was able to buy an AS-3 flash adapter for the F3. With the F3s mirror locked up I also had to use an hand-held light meter. With amazing depth of foield focusing was never an issue. The old zoom lens had six filters on a wheel. One was a skylight and the other five were strongly colored for B&W film. While I liked the circular results, using the lens was a hassle. I often had my shoes or forehead in the picture. On a sunny day, my images suffered from solar flares. My new Nikon 8-15mm AF-S fisheye has none of those old problems. It fits on my DSLRs without any problem. It doesn’t need an external finder or separate light meter. At the 8mm setting (and lens hood off) I get a circular image very much like the vintage fisheye. The new lens is faster and focusable. Like my 14mm f2.8 Nikkor, this zoom uses gel filters inserted in the rear of the lens. I really don’t like this arrangement. This fisheye is similar in weight and size to the 14mm lens. I am also not fond of the electronic aperture control first seen on G lenses. Without an aperture ring one cannot use this zoom on older cameras. At the longer end of the zoom range (12-15mm) the image fills the (FX) frame and lens hood stays out of the way. This image is similar to my inexpensive Bower (Samyang?) 8mm fisheye with its fixed lens hood (and DX coverage). So far I haven’t used my new lens much but I think I will like it.

Tripod adaptor was well worth the money. Great way to clearly see objects at a distance without a shaky view.

The 4MM lens gives a better view than the 8MM. I'm using the Arecont Vision AV20275DL to get a 180 view of areas of a park. The smaller lens gives up distance for a better wider viewing angle. I've tested the 2.8, 4, 6 and 8mm, the 4mm seems to be the sweet spot. These are OEM lenses and worked perfectly as a substitution for the 8MM.

This works well as a head strap but it also works if you want to use it to wrap around something that may be easily scratched. This could mean the side view mirror of a car or maybe just to wrap around your pet. Over all, this product is one to have handy.

This rear cam is small enough to not interfere with your view out your back window. The picture quality is great!!!

I purchased the Odyssey (regular, not pro) knowing that the image in the pro model's eyepiece was the same as the image on my iPad Pro. B&H shipped it quickly, and the packaging was terrific by Unistellar. I was able to image Comet 12P, Pons Brooks, easily in the bright skies in my DC suburb. Also was able to image many other objects. My use is EAA, not astrophotography , showing objects that my visual scopes cannot view well in light polluted areas. My grandkids will love sharing the view too. I need to spend more time on various objects, and then post process a bit. Great for galaxy season.

I love macro photography and decided to buy these filters for a different view of objects. I have not been disappointed

I live in a light polluted area and do not have a "Go To"mount. I purchased this eyepiece for the wide field of view and low power which enables me to sweep the sky to find objects. I knew about the wide FOV but have been pleasantly surprised by the color and clarity of the objects I view. I cannot detect any distortion even at the edges. This is an excellent eye piece for wide field viewing needed to search the sky. I recently purchased a 2 inch Barlow lense and am anxious use this eyepiece with higher magnification.
