New Never Used Altair GPCAM3 287M Mono USB3 Camera. RVO has purchased this camera but it has never been out of the box or used. 3 months warranty.

The Altair GPCAM3 287M is a specialist solar, planetary and guiding camera with an extremely fast frame rate and Global shutter. 

The frame rate can reach a maximum 540fps on a high-end laptop, earning it the nickname of Baby Shark. 

The 0.4mp sensor has 6.9µm pixels in a 720x540 pixel array to suit long focal length telescopes. 

This camera is of particular interest to planetary, lunar and solar imagers, especially for long focal length, high resolution imaging. We recommend this camera for advanced users, who are familiar with long focal length imaging with a crop factor.

 

The pixel size is well suited to refractors of 115mm or larger, and the Altair Solar Wedge and 2-3X Flat Field Barlow, or the DayStar Quark, as well as reflectors of larger aperture using Baader Astro Solar Film and the Altair NUV 395nm filter.

Auto Guiding:

Another application is guiding with an OAG or Off Axis Guider, where the relatively large pixel size would be ideal for guiding at the full focal length of the main imaging scope. The camera has an ST4 auto-guiding port, and can be used to auto-guide directly with mounts from all the major manufacturers.

Lunar and planetary imaging: Not only is the GPCAM287M ideal for high speed Mono planetary imaging with filters, but also delivers impressive high power lunar imaging results with large reflectors. 

File formats: The camera supports 8bit or 12bit ADC output. The camera can be fully controlled in AltairCapture and SharpCap to output uncompressed .AVI and .SER video files for solar system imaging, compressed MP4 files for social media uploads, as well as all common still image formats such as .JPEG .PNG (12bit) .TIFF (12bit) .BMP, and .FITS (12bit) for deepsky imaging.

Included in the box:

Camera body with dual USB3.0/2.0 socket and ST4 guide port.

1.5m High-speed USB3.0 cable.

1.5m ST4 guide cable.

1.25 inch x nosepiece with female 1.25" filter thread on the front.

Why Buy Anything Else
27 June 2019  | 

Firstly, great service by the RVO team yet again and super fast delivery, cheers team

I bought this camera following weeks of research and many discussions on astronomy forums. It is literally a mine field out there of which camera is best and should you go DSLR, CCD or CMOS also USB 2 versus USB 3, and various debates on deepsky cameras versus planetary and so on etc etc.

I came to this camera because I have heard good things about it from experienced and seasoned astronomers. The camera is a good 'one for all unit'.

On receiving the camera it took a few minutes to download the Altair drivers and within five minutes I had live images on my screen, took single shot images and also video within 10 minutes of having the camera on screen. The Altair site is also very useful with easy to follow instructions to get the camera working out of the box.

Read the Altair details on this camera, they concur to what the experienced astronomers have told me, that this camera is a good all rounder for Deep sky, planetary and solar imaging and the USB 2 interface is by no means a problem and does not impede operation or performance.

For me this camera is perfect, great value for money and something to which I can grow with and evolve. The full package with the wide angle meteor lens is worth the 20 extra too if you can stretch to it, but you can always buy these at a later date if not.

The main thing is to get out there and use it

Zygo Interferometer Testing For ED Refractor Telescopes!

We are extremely pleased to announce our Zygo Interferometer is now installed and ready for use! Our experienced staff can test refractor lenses up to 120mm aperture and provide a comprehensive 2 page report showing the optical quality and Strehl ratio, plus much more information. We are using the very latest Zygo MX software to provide a more detailed report compared to other standard reports.

 

The interferometer is essentially a measuring instrument. Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen. From this, we can adjust the position of the test optic and the reference sphere to obtain a perfectly calibrated system. The more central the laser to the test optic and then on return, the better and more accurate reading and measurement we can take. This takes a lot of adjustment to get the best results from the optical surface. Once the measurement has been taken, we are provided with a series of results that show the optical quality of the surface plus other information. Continue reading for an explanation of the individual values and you can also see a test report that was done on one of our RVO Horizon 60 OTAs. 

We are offering certain telescopes with a Zygo test at an extra cost. Mainly ED doublets and triplets. All available telescopes with a Zygo test report are listed here. Just select Zygo Test Report from the drop down box at the top of the listing and we will test the optics in house and provide a full 2 page report with your scope. This will show you the optical quality of your telescope optics. We can also offer this service on your refractor telescope. Please get in touch for more details about this. 

At Rother Valley Optics, one thing we pride ourselves on is customer service and quality of our equipment. When we test your telescope, we will ensure that it is of the highest quality otherwise, we will reject the scope under our strict quality control and test another model for your peace of mind. One of the main values to look at when testing a refractor is the Strehl ratio. The higher this number, the higher quality lens you have. At Rother Valley Optics, we will guarantee the highest possible Strehl ratio for your telescope.  We will aim to provide 0.95 Strehl or higher on Takahashi, RVO Horizon, William Optics and many more! Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument. 

Other measurements such as the PV and RMS are important too. With these measurements, the lower the number the better as it shows less curvature on the lens. The flatter an optical lens, the better it will perform. The PV rating (Peak To Valley) is a measurement from the highest point (Peak) to the lowest point (Valley). From this we get the RMS (Root, Mean, Square). This is a similar figure to the PV and measured exactly the same way. The RMS is basically an average height difference from the PV so again, the lower the better. As you can see form the example below, we measured an RMS of just 0.027 wave which is a very good value.

We also measure the Power with our systems which is essentially the error from the reference sphere to the test optic. The reference sphere we use on our system is a very high quality sphere so the closer to zero the Power, the less error between the 2 elements thus ensuring a higher quality optical surface. 

You will also see some more values such as Astigmatism and Coma. Again, these are measured by the interferometer when we take measurements of the optical surface after adjustment. These are values which ideally would be at 0 but as our test optics are all curved lenses, there will always be astigmatism and coma present. The lower the number, the less of these aberations you will effectively see but with most refractors, you can buy field flatteners which will compensate for the coma anyway. The astigmatisms value is explaining the error between the symmetrical curvature of the lens. Basically, no lens will be perfectly symmetrical, the lower the astigmatism, the more symmetrical the lens surface is. 

Once the Zygo test report has been completed, the optical alignment is thoroughly tested and tuned to ensure they are spot on before they leave us. 

All available telescopes are on the website at the link below and ones we've tested already that are available straight away are also listed.

Here is an example of the test what we provide. This was a test on one of our Horizon 60 ED OTA's.
