3.0 de un máximo de 5 estrellas Amaze your family and friends! Even with modest equipment, this camera produces excellent planetary images. 6 de julio de 2016
Por J. Palmer - Publicado en Amazon.com

UPDATE 3/31: I removed a couple stars because after one year of careful use, the glass popped out of place. This let dust and dirt fall inside, and ruined future captures, even after gluing the glass back in place. I didn't drop or smack the camera in any way, and it was always carried in a padded case. I took it apart a 2nd time to clean the glass and sensor, and I saw that the sensor now had a scratch from the loose glass. When I cleaned the dust off of the sensor with dedicated sensor cleaning supplies, it scratched terribly. This all happened at the worst possible time, as I was working hard to capture Jupiter near the time of 2017 opposition. Since this happened after a year, and some of the damage was caused by my own actions, I had no choice but to replace the camera. Very disappointed.

Original Review:

Before I bought this camera, I was learning how to do Astrophotography one step at a time. First, I was snapping single frames with my Alpha A57 on a 130mm reflector. I could scarcely see a gap between Saturn and its rings, or see any type of detail on Jupiter's surface. Next, I learned how to take many pictures and stack them together. Now, I was getting little closer, but I was still very discouraged. Next came some video on a 8" SCT with my A57, followed with stacking in Registax, which produced some decent beginner images. After seeing some examples online of others' images, I knew I had to make the leap to a dedicated astro camera, if I were to make any progress. I've been very happy with that decision! Although it takes a little more planning to carry a laptop outside with me, it's completely worth it.

The camera is surprisingly small and lightweight. It functions like a 5mm eyepiece, so I generally center the object with a low magnification eyepiece, then add the barlow and recenter, then add a high power eyepiece and recenter, then insert the camera. On the computer, select a large video size and adjust the exposure and focus the telescope until it comes into view. Then, you can begin adjusting the video size and make you final videos. I always do a couple videos for each combination of settings.

Here are a few other suggestions based upon what I've learned so far about planetary imaging:

1. The best quality to file size ratio I've seen has been with the Y800 format.
2. I have to leave myself a lot of space around the planet, so that I can keep the disk away from any visible specks in the telescope.
3. I've had the best detail with a 3X barlow, with no binning. This is with an 8" Celestron SCT.
4. Quality is 60% seeing conditions, 30% post processing, and 20% telescope. If the planet is high in the sky and it's standing still, you're going to get a fantastic video. You will not be able to get a good final image if the planet is too wobbly. You just can't. I tried many times before I had the sense to just try again on another night.
5. Visit ClearSkyAlarmClock.com to generate customized advance notifications of good seeing conditions. If I didn't have that, I would have missed my best pictures!
6. Framerate is your friend; make it as high as you can by reducing the dimensions and using a faster shutter speed.
7. Use the histogram feature in iCap to ensure you're not overexposing.
8. The best viewing occurs near opposition and/or perigee, when the planet is brightest and/or closest, and only when the planet is high in the sky.

4.0 de un máximo de 5 estrellas Nice package with a couple of minor annoyances. 18 de febrero de 2015
Por Rick Evans - Publicado en Amazon.com

Acquired the NexImage 5 MP to do Solar System imaging with a Celestron 8 SCT on an AVX mount. You cannot ignore the equipment you mate the imager to when judging its performance. The laptop I use is a duel core 2.16 Mhz laptop equipped with USB 2.0 and 3.0 ports.

The imager includes a screw in 1.25 inch nosepiece along with a screw in dust cap and a heavy duty USB cable. Also included is iCap acquisition software and Registax 6 freeware for processing videos into still images. You don't have to use the included software if you can find something you like better.

The target market for NexImage 5 are hobbyists which means you're expected to figure things out without much hand holding. iCap includes a help file to get you started acquiring. But it doesn't offer tips on how to set gain and exposure, how to get the best focus or how many frames or how long to run the video. I run iCap on Windows 7 64bit. iCap provides a variety of settings and if a feature is not available it is disabled. You can also add or remove tool bars that are disabled or you don't use.

Imaging can be done in color or monochrome and there are 9 image size formats for the non-binned mode. There are two binning modes 2x2 and 4x4. This review doesn't deal with those. This review does deal with acquisition. Registax 6 processing software is third party software that was not written by the manufacturer.

The number of frames acquired per second is limited by the image size. On my setup this is typically as slow as 6 fps for the largest format (2592x1944). I only use this format in live view to help get a target into the field. I drop down to one of the lower resolutions that depends on what I'm imaging. iCap help won't give you much guidance on what gain, exposure or number of frames to take. The software provides a histogram function which should typically be set to be as wide as possible without hitting the 255 level.

Clear nights with excellent seeing are rare in New England or the Mid Atlantic States where I do my imaging.But I have had some success imaging the moon, Jupiter and Saturn and Mars. I'm amazed at how the combination of the NexImage 5 with Registax 6 processing can yield quite nice images even when seeing is mediocre. My imaging has been between 300 and 600 frames where 50% of the best frames are selected by Registax 6 for averaging.

I knocked off one star because of two annoyances. Often while focusing live view simply stops forcing me to restart it. The second annoyance is sometimes vertical red lines appear in the final image. They can be eliminated with careful adjustment of wavelets noise reduction. Otherwise I'm quite happy with the NexImage 5. A prime focus Jupiter image taken in January is attached.

5.0 de un máximo de 5 estrellas It works if you have a nice mount 23 de julio de 2012
Por WarmWeatherGuy - Publicado en Amazon.com
Astrophotography is not as easy as some people would like it to be. There are two basic classes of astro cameras. One for dim objects and one for bright objects. For dim objects you might need an exposure of 5 to 10 minutes. For bright objects you might need an exposure of 1/30 of a second.

This camera is for bright objects like the Sun (with proper Sun filter), Moon, Jupiter, Saturn, Mars, and Venus. You won't be taking any pictures of galaxies, nebulae, or star clusters with this camera.

Planets are small with an angular size of maybe 20 arc seconds. Ideally you don't want to use any eyepiece. The image of Saturn (for example) as projected by most amateur telescopes will be very small so they build the camera with a detector with very tiny pixels all packed together. This way the image of Saturn will be spread across a few hundred pixels instead of just 5 pixels. Consequently the field of view will be very small and your telescope mount needs to be high quality. I have gotten a nice picture of Saturn using my NexStar 5SE but it is much easier with the CGEM mount. If you have a shaky tripod you're out of luck.

Focusing is extremely important. I use a Bahtinov mask. I point the telescope at a bright star and focus with the Bahtinov mask and then point the telescope at Saturn. Unless you have a really good mount with an accurate finder it will be very hard to find Saturn with the very small field of view you get with this camera. If you use an eyepiece to find Saturn and then switch to the camera you won't be able to get an accurate focus except by chance.

I have used the original NexImage and now the NexImage 5. The NexImage 5 allows me to get nice pictures of Saturn without having to use a Barlow lens. With the older NexImage I would need a 2X or 2.5X Barlow to get Saturn to be the size (in terms of number of pixels) as I get with the newer NexImage 5. Also, with the NexImage 5 I can presumably get 50 frames per second. I say presumably because I can't do it with the cheap laptop computer I am currently using but I can with my desktop computer. I now need to buy a new laptop. High frame rate is important to remove atmospheric disturbance with RegiStax, the stacking software you must learn to use to get really good pictures.

To see what is possible I suggest visiting the "Solar System Imaging & Processing" forum at Cloudy Nights (cloudynights.com). If you're a complete beginner I would recommend getting the original NexImage first. They are discontinued but used ones still show up on eBay. Or you can modify a web cam.

5.0 de un máximo de 5 estrellas Great intro to astrophotography, minus the headache 4 de febrero de 2015
Por Viniguez - Publicado en Amazon.com

I’ll begin this review by stating that it would be unfair to compare thousand dollar CCD cameras, apples to apples, with this product.  Instead, I will review it for what it is and that is an affordable and easy to use introductory camera for planetary imaging, aka, astrophotography.  With that said,
this camera is anything but a lemon. 

I’ve recently felt the need to properly review this product after hearing people disparage the use of such “cheap” cameras to beginners at star parties.  Astrophotography is by far the most daunting hobby I’ve ever started. I stumbled to where I am now thanks to the help and experience of others.  There are plenty of online resources you can scour before making your first imaging camera purchase.  However, most people stop at the purchasing recommendations and don’t find out about the challenges involved with complicated cameras until after they’ve already purchased the camera and hit a road block.  This is where this camera shines.

This is by far the simplest and most enjoyable camera I’ve used for planetary imaging.  While you won’t get as clear and high definition of an image as you could with the Skyris monochrome series, this is more than enough sensor for any beginner.  At this price point, you are getting a great piece of camera that won’t hurt your wallet should you reach the conclusion that astrophotography is not for you. You don’t need to spend thousands of dollars to figure that out.  No matter what that one guy at the star party

Either way, I hope this review helps anyone considering this as their first astrophotography camera. This is a difficult and humbling hobby to pick up but by far the most fulfilling. 

Clear Skies,

Victor I.

5.0 de un máximo de 5 estrellas Windows 8.1 ready! 13 de febrero de 2015
Por Scott - Publicado en Amazon.com

I just had to post this ASAP. I have not used it for imaging but I just wanted to make it clear that this works with Windows 8.1 out of the box. I have a Windows 8.1 laptop and was a little nervous about compatibility, especially after reading some reviews. Well don't sweat it. I loaded the DVD and then installed Registax and iCap. I then connected the camera up with the included USB cable and pressed the 'install driver' button, it proceeded to load the drivers. I had to grant permission to load them after I got a Widows security prompt and bam, the cam worked in icap. I'll update this review after I get to use it, but I don't anticipate it will give any trouble and will yield excellent results.
