The 130SLT + the $75 Celestron wifi module = awesome. As a beginner, after a couple times I was able to do a 3 star alignment quickly (under 5 min) with this scope using my iPhone. Optics are great, split double stars and Hercules cluster looked great, can see the bands on Jupiter and it's moons. Earth's moon looks incredible!!Pro's:-light weight easy to travel with-good optics even with 5" primary mirror-great Goto accuracy with 3 star alignment-super easy to collimate primary mirror-easy setup, 10x easier than a GEMCon's:-the OTA is bit much for the mount to handle. If using on a deck you will need to get vibration suppression pads!-Alt az mount is limited to like 70 degrees up so no looking near the zenith of the sky.-need lots of extra parts for a good setup, see recommended list below.Recommended need to have extras:-Celestron Skyportal app (free)-Celestron power tank ($60) for use at dark sites-Celestron Power adapter ($20 if using near a power source)-Celestron Wifi dongle ($75)-2x Barlow for planetary and moon-moon filter so you can observe the moon ($20)Nice to have accessories:-Orion Accufocus $80 (stops shaking of OTA when you manual try to focus and dials in precise fine focus)-Skyglow light pollution filter if using in a light polluted area-Mead 12-24mm zoom eyepiece-vibration suppression pads ($25)-reticle laser eyepiece for centering stars during alignment ($40)Tips n tricks:-the "grease" that comes stock on the focuses is terrible, practically glue like. Carefully disassemble focuser (easy) clean and re-grease. I used Phil Wood's bearing grease I already had for my bikes. Removes most of the "slop" and "stiction" in the focuser.-make a 4" dew shield if viewing in areas with stray light pollution to improve contrast-place a 5lb weight on the tray to stabilize the mount-get vibration suppression pads if using on a deck or concrete!!!-my wifi module or AUX port was not making a good connection, not sure which so I returned the scope and upgraded to an AVX with CN8. If you get this problem, use a rubber band to pull the wifi module tighter into the AUX port-instead of getting a $50 illuminated reticle eyepiece for centering stars during alignment, you can defocus the star instead and make it large to center in the FoVIn the end I upgraded to an 8" reflector with an AVX GEM mount. However, the 5" 130SLT was like 10x easier to use and setup... if I had to do it again for visual use I would look at the 8 or 10" Orion GoTo Dobsonian's for sure! A GEM + Newtonian scope don't mix, bad combo. For the price tho and ease of use, the 130SLT scope is awesome. However, for it to be fun to use you need to spend about $100-150 in extras.

I’m using these indoors as satellite / rear speakers in a 5.1 setup - the front left/right are also Moukey, bigger shelf sitting models. In this use case they are an excellent upgrade from my prior Sony speakers. With multiple drivers and lower impedance, they create a powerful but clear sound. They were easy to mount (I was able to use the existing universal mounts I had used to wall mount the Sony speakers) - the wiring is all the same as typical speakers - red and black speaker wire, the higher quality the better.They do have multiple mounting options - they come with a swing bracket attached that can easily be used - because I have the universal mounts already tied into studs, I didn’t end up using them - if you remove them, you can access a typical “keyhole” type mounting system integrated into the back of each speaker which is what I’m using.Because I’m using these indoors, I can’t really comment on the waterproof capabilities (or lack thereof) but they do seem to be at least as well weatherproofed as the outdoor speakers that I currently use so I think they’d hold up just fine as long as you can protect the wiring connections from getting wet.Overall, nice speakers and a decent value at the current price - definitely give these a look if you’re in the market for new speakers!

I ordered the 52mm filter because the 30mm f1.4 sigma lens for sony e-mount cameras has a 52mm thread but after lens arrived, I couldn't fit it on.But after-service support was pretty helpful in telling me this

Light works well but it small. I was hoping I would be able to mount my Sony a 6400 in the center but it’s too small. You would definitely need a very tiny camera. I have my camera on it’s own tripod behind the light in my photo attached. Light has a nice brightness, multiple settings and does the job.

When you read reviews you often see things like, not good for "deep space photography" and "too much color." These comments are true...to a point! I have had my Celestron 6" for over 10 years. This review is primarily for the optical tube since mine was used originally on an Celestron ASGT mount, the precursor of today's AVX.The tube is very large! Yard cannon is pretty appropriate! My son brought me my telescope from Oklahoma in the back of a small Nissan. Mount and tube took up most of the space in the car and my sons had to put their bags on top of the optical tube in the backseat. The ASGT mount, which is pretty much the same as an AVX mount, was sturdy and tracked well. The main issue with this scope is that the legs don't go high enough in some positions so you have to lay on the ground to look through the telescope. An extension from Orion solved that issue. The mount is also a bit light for a tube of this length. There is a lot of vibration if touched or bumped. Overall the telescope worked well with with this mount and was was even useable for imaging.The telescope itself was well built and came collimated. The focuser on my tube was marginal. I think Celestron has upgraded this piece in the last few years so don't know if it is still an issue. I was using a heavy SBIG cooled CCD camera and the focuser was not up to the challenge of holding it steady. So I replaced the stock focuser with a 2 speed focuser from GSO. Now it works well for any camera or eyepiece.In a 6" F/8 achromat you do get false color or chromatic aberration, but not as much as expected. It does not affect the views of planets or even the moon, other than a purple halo around bright objects. I now use a Minus V filter along with a UV/IR cutoff filter for imaging. This cuts the CA down to minimal levels. I have never found it to be a big deal but some people do. If you do then this type of scope is not for you. However, for the quality of the view, the cost and the size a little "purple haze" is a small price to pay.You can image deep sky objects. Be prepared to use routines to remove the false color if you use a one shot color camera. However, if you use a monochrome filter and 3 color imaging to make color pictures these things are awesome. Or you can do what I do. Most of my imaging is to do scientific photometry so I use narrowband photometric filters that eliminate the CA. You just have to know the strengths and weaknesses of the telescope to be able to use it effectively!The first image is from an Achromatic 4" with a F/6.5 focal ration. Notice there is little color in the image and it was taken with a one shot color video camera.

V860-IIIS (S stands for Sony). I purchased this flash to mount on to my Sony A7R3, and I am satisfied with the product. Just mount it on the camera and you are good to go, as the set up is as simple as opening a can of soda. I use the TTL auto mode with auto settings and it works great. The front dual option light/flash gives an added versatility of using it as a light, flash or not use it at all. The flash includes an array of coloured cards, which helps a photographer to be creative and experiment with adding colour to flash light. The flash head can be tilted at direction and can be used in combination with other off-camera flashes. A good product!

Very impressed with this camera mount. I don't even feel my Sony camera while hiking. Easy to release when I want to use it. Haven't tried it yet with my heavy Nikon D3 hoping it will also be comfortable and secure.

After researching telescopes, I narrowed the choices down to an SCT (Schmidt-Cassegrain, aka SCT, or "CAT -- for catadioptric), then to anything 8" aperture or larger, and finally chose Celestron over Meade (arguably the top 2 of 3 manufacturers). Celestron has a variety of 8" and larger SCTs. These are powerful, flexible, and ... get this, you can transport this big 'scope to most any site, even at 42 lbs (telescope) and 20 lbs tripod. And when it comes to astronomy, SIZE MATTERS! Try that with a dobsonian 'scope and you will also need a moving van, and friends.I am newly returned to astronomy, and love this machine. System uses GPS and a variety of alignment methods -- read those important instructions FIRST and they do work. In short order I was tracking on a wide variety of objects -- moon, stars, DSO (deep space objects).To learn (and verify) tracking, I found a polar star (stays overhead), and let it track for 6 hours. From the time I centered the star in the eyepiece until the next morning, the CPC 800 kept perfect alignment. The huge object library provides educational "go-to" capability, just understand that the system will limit, and offer to you, what is viewable, not necessarily available.You will receive a 40mm eyepiece, produces 51x magnification. In spite of what you may read, this is a great starter eyepiece, provides a wide field-of-view for amateurs so that you can relate (identify) what you see to what your star chart/planisphere has. I now use a 32mm (x62 mag), and a zoom 8-24mm (250-84 mag). A longer eyepiece focal length makes it easier to see through, but less magnification. The smaller the eyepiece focal length (eg, 6mm) the greater the magnification, but also the more difficult to keep your eye in position (eye-relief), and a much narrower field of view. You will also accumulate color filters for pulling out planetary highlights, and other filters for restricting certain light wavelengths that clutter and obscure your targets. In short, you may likely spend half-again as much on acce$$orie$ !!I bought the Celestron power tank, simplifies power needs no matter where you are, works great. And a DEW SHIELD, to keep moisture off your optical lens. And a 'scope case, and and and.Lots of SCT reading references are available here on Amazon, including anything by Terrenace Dickenson and Alan Dyer, "Turn Left at Orion" (how to find DSO targets), "Choosing and Using a New CAT..." and many others will help you.Bottom line, these are all great things to experiment with, but the basis of your hobby needs to be rock solid, and this CPC 800 is your foundation. It's easy to become frustrated learning astronomy, a trusty 'scope that delivers images beyond our own existence will help keep you engaged, and interested, and may -- even -- help you want to learn more.I am moving up to the CPC 1100 (11 inch monster), so there we are. Dark Skies.ps: if you are looking for astro-photography, the SCT lineups are fabulous for this. But also understand you are taking on 2 serious and expensive hobbies. Not for everyone, just saying.pss: Yes, this telescope is made in China (as are most these days), and the quality is oustanding.
