I decided to buy SVBONY SV305 Pro to test it for lunar imaging and planetary imaging. On the paper, it looks promising and is also affordable for beginners as an upgrade from a webcam or cheap planetary cameras. It is the same camera as standard SV305 but with the USB3.0 interface.

SVBONY SV305 Pro is a high-speed 2-megapixel planetary camera using a SONY IMX290 CMOS color sensor. The PRO version of the SV305 has a USB3.0 for high FPS. It is compatible with Windows, Mac OS, and Linux operating systems. The camera can be used for lunar imaging, planetary imaging, and as a guiding camera. 

You can buy SVBONY SV305 Pro camera on Amazon.

What’s In The Box?

SVBONY SV305 Pro comes in a nice box with everything you need to start using it right away. Here is the list of items you can find in the package:

  • SV305 Pro Camera
  • Dust Cap
  • C-Mount to 1.25 inches adapters
  • USB 3.0 Cable A-Male to B-Male Adapter Cord (2 meters/6.5 feet)
  • ST4 compatible autoguider cable (1.5 meters/5 feet)
  • User Manual (EN/JP/RU/FR/DE/IT/ES)
  • CD with Software and Drivers (can be downloaded online)
  • Cleaning Cloth

SVBONY SV305 Pro Build Quality

I expected a bigger camera, but after I opened the box, I found a little lightweight camera made from machined aluminum with a dark grey finish. The case of the camera is one sturdy piece with a back cover attached by bolts.

The first impression of holding the camera was surprisingly good. The build quality is excellent, and there are no plastic parts which I like. On the backside are the USB3.0 port and ST4 port for auto-guiding. Cables and adapters are also high quality.

The SV305 Pro features a built-in 128MB DDR Buffer. The buffer will cache the image and transfer it to the computer when the USB is not busy so the frames will not be lost. It is also beneficial for slower computers with USB3.0 to capture frames in high FPS without any loss.

SVBONY SV305 PRO Drivers and Sofware

SV305 Pro drivers are available online on the SVBONY website. They also come on the CD in the package but who is using CDs these days. I recommend downloading current drivers online here:

The camera also supports the ASCOM Platform, and it can be used on all operating systems, but you need the right software that supports the SV305 Pro. The camera is also compatible with the PHD2 for auto-guiding. Here is the recommended software for each operating system:

SVBONY SV305 PRO Settings

The settings for the SV305 Pro will be different for every telescope and object you want to capture. But I want to explain the main settings, so you get an idea when setting the camera.


The camera offers 8-bit and 12-bit output. There is also an RGB24 setting. Don’t be surprised when shooting in the RAW 8 or 12-bit mode. The image will be black and white, and you have to process it to get colors. 

Choosing the RGB24 will produce a color image right away. However, you always want to shoot in RAW mode. I use the RGB24 only for all-sky time lapses with a wide-angle lens. 

For planets and the moon, I use 8bit RAW mode. It will give you more FPS than 12bit mode, and it is sufficient. The 12bit mode is better for Electronically Assisted Astronomy(EAA) capturing the deep sky objects because it has a higher dynamic range than 8bit.


Gain settings are different from other cameras, and the range is from 0 to 30. SVBONY explains this as an “easier to understand range.” 

Basically, the number zero is minimum Gain, 30 is 30x brighter than 0 Gain, 15 is 15x brighter than 0 Gain, and so on.

Exposure Time

You can set exposure time from 1ms to 30s. The higher the exposure time is, the lower FPS you will get. So try to use as low exposure time as possible and give it more Gain. 

The Gain will bring more noise to the picture as well. You have to play with it because it varies from telescope to telescope, and it also depends on what object you are trying to capture. 


The big plus of the SV305 Pro is that it supports the ROI or Region Of Interest. It essentially captures only the part of the sensor you choose. This feature is needed when capturing the planets because if you use a smaller ROI, you will get more FPS.

The full resolution is 1920×1080, and you can go as low as 360×240 if the planet is tiny on the sensor. You don’t need to capture all pixels on the sensor, and the FPS will increase rapidly with a smaller ROI.

FPS with USB3.0 vs. USB2.0

Measuring the FPS for each camera resolution is hard because you would be using different settings each time. So, to get a baseline, I decided to do it like this. To measure the maximum FPS, I’m using 0 Gain and 1ms exposure time with the dust cap on the camera. 

Keep in mind that you can’t get this kind of result in real situations. The FPS will be lower by increasing the Gain and exposure time. So here is the table of maximum FPS for some resolutions in SharpCap and AstroDMx over USB3.0. 

SharpCap USB3.0

1920×108040 FPS
1440×80070 FPS
800×600168 FPS
640×480260 FPS
320×240260 FPS

AstroDMx USB3.0

1920×108062 FPS
1440×800100 FPS
800×600250 FPS
640×480333 FPS
320×240333 FPS

I’m also including a table of FPS using SV305 Pro with SharpCap over USB2.0. 

SharpCap USB 2.0

1920×108016 FPS
1440×80030 FPS
800×60070 FPS
640×480110 FPS
320×240260 FPS

SVBONY SV305 Pro UV/IR Cut Filter Removal

The one thing I don’t like about this camera is that it has a built-in UV/IR cut filter. I understand the decision to put this filter in the camera; it is marketed as a guiding camera, not a planetary camera.


But this camera has a SONY IMX290 sensor which is great for planetary and lunar imaging. Don’t get me wrong, you can use it to capture the moon or planets with the built-in UV/IR cut filter, but here is my issue.

If you want to do high-resolution planetary/lunar imaging, you need perfect seeing conditions. It doesn’t matter if you have the biggest telescope and the best camera because if there is a lot of atmospheric turbulence, you won’t get a good image with high details.

We use IR pass filters to capture only the infrared light coming through the atmosphere to fight this. The advantage of this method is that the IR light is least affected by atmospheric turbulence. These filters are cheap, and they provide excellent results.

SVBONY IR Pass 685nm Filter

And because the camera has the UV/IR cut filter, you can’t use it with the IR pass filter. The UV/IR cut filter is cutting too much IR light, and the solution is, of course, to remove the built-in filter. Another plus is that the IMX290 sensor is highly sensitive to IR light.

Removing the filter is easy, but you will lose the warranty, and if you are not comfortable with electronics, I don’t recommend you do that. Here is a quick image guide describing the process.

First, remove the bolts at the back and remove the cover. There are 4 small screws on the side at the bottom holding the camera electronics in the case.

To remove the filter, you have to push it out of the housing. I had trouble pushing it out, so I put something of filter size on top and gently hit it from the top.

Don’t worry if you break the filter because you can buy the same UV/IR cut filter for a few bucks on Amazon and screw it on the camera if you need it in the future.

My Experience With SV305 Pro Capturing The Moon

After I removed the UV/IR cut filter, I was ready to try the camera on the moon. I’m using IR Pass 685nm filter also made by SVBONY. The telescope I was using for this test was a SkyWatcher 130P reflector on AZ GoTo mount

I also have a Skywatcher 200P for planets and moon, but the mount is on RMA in Germany, so I could not use it. But even with the 130mm aperture, I was surprised by the results I got from the little camera. Here is the image of the Montes Apenninus on the moon.

Montes Apenninus

I took an AVI video of 5000 frames and stacked them with Autostakkert! and then only applied the de-noise filter in PS. I think the result is nice with this telescope and SVBONY SV305 Pro.  

One interesting takeaway is that using 0 Gain; I got strange artifacts after stacking. But when using some Gain(10-15), the image was free of artifacts and much sharper. So if you have the same problem, use Gain.

Removing the UV/IR cut filter and using IR Pass 685nm filter really helped because I was trying it the night before I removed the UR/IR cut filter, and the result was not very good. 

Here is the picture I took before removing the UV/IR Cut filter, and you can see that there are fewer details in the image. It is a slightly different picture, but I was using the same telescope and SV305 Pro.

Montes Apenninus

Unfortunately, the planets are not visible at the time of writing this review, so keep an eye and subscribe to my YouTube Channel Astrotol, where I will be uploading videos about the SVBONY SV305 Pro camera capturing planets and more.

SVBONY SV305 Pro Astrophotography

This camera is not made for astrophotography, but you can use it for EAA. The problem here is the small sensor which results in a small field of view. It also requires good tracking and autoguiding for long exposures.

It is more suited for galaxies than nebulae. I will be trying to capture some galaxies later for sure with this camera. But I pointed the telescope to M42 and took few exposures, and I also tried Live Stacking in Sharpcap. 

Stacked 20 frames. Exposure 20x8s.

I see potential here, but I have to test it more with different targets. The moon was bright and almost full, so not ideal for this kind of work.


I’m thrilled with the SVBONY SV305 Pro because you get an excellent piece of kit for the price. The ZWO ASI290MC uses the same sensor and is better in some areas because of different electronics and no built-in UV/IR cut filter, but it is also more expensive.

If you are a beginner and want to try planetary or lunar imaging, I recommend the SV305 Pro over the ZWO ASI290MC. You won’t be missing out, and you save money.
