SV305 Longer Exposure Time 1800S

SV305 Longer Exposure Time 1800S

SV305 Longer Exposure Time 1800S

Customer(C): Is SV305 camera a deep sky camera?

Svbony (S): Nope, Svbony SV305 is a planetary camera.

C: What’s the exposure time of your SV305 camera?

S: How long exposure time do you need?

C: 3mins is enough.

S: We design 30mins for people using it. People could try it to capture the object they want. Maybe could get some bright deep sky object. But please remember SV305 camera is a planetary camera, it doesn’t have a cooler. So please don’t judge it as a deep sky camera. Thanks very much!


Why SV305 camera has 1800s exposure time?

As we all known, the Svbony SV105 and SV205 only have 1000ms exposure time. People always say is there any way to make it longer? Svbony is still working on that. We are making the upgrade firmware trying to make it longer exposure time. But depend on the CMOS sensor and the total project, this is not that easy. But the 1 minute firmware is in the testing now. well be release soon.

Meanwhile, we are producing a new SV305 camera. and we designed it new camera with a total new project, and a better CMOS sensor. The sensor could support over one hour exposure time. In order to give customer the best astronomy experience, we only support the SV305 30mins, 1800s exposure time. The longer exposure, the hotter the camera will be, and there will be more read noise on the image. So 1800s is enough.

I asked this question on Facebook, “How long exposure time do you respect on SV305 camera?” many people told me 3mins will be enough. And some people also said 10mins will satisfy them. So we are trying to make it longer exposure time and also give quality image. And there is the longest 30mins exposure time.

How many read noise when exposure 1200s?

Here is a picture of the testing results.

Do you think the 1800s (30mins) is long enough for astronomers to capture the planetary? 

Welcome all your ideas to help us to be better. Please send email to info@svbony.com. Thanks very much for your reading!

Hi I purchased a SV105 a year ago and works great for planetary imaging but yeah would be nice too have a bit more exposure time than .5 sec. I am part of the svbony group on facebook. I noticed and read above back in 2019 that there was progress on a firmware update to possibly increase exposure time to 1 min or even 30 sec for the SV105 and SV205. Which would be great for M42 and other bright steller objects. What ever happened to this development? I understand that these are UVC cameras but would be nice if there was also custom windows driver you could install to incrase the exposure a bit? Can you send me this development firmware for testing to me?

I think SVBony are doing a very good job at making quality products for astronomers! Well done! Please, we would like to see the firmware upgrade to SV105 for exposure (even if only 30seconds). Do you know when this firmware will be released? Many thanks Paul

You really need to clean up your written material. One one hand it looked as if developing a 1 min exposure firmware was a work in progress BUT later you mention that you have indeed developed a 30 min exposure device. I need to have at least a 180 second SINGLE EXPOSURE setting. Like this, I need to take upto 25 such exposures. I have placed an order for the product BUT saw reviews that the product cannot have exposure more than 1/2 second. So I am not sure which is true. Hopefully I don't have to return it

Hi, if you read the article that Rita wrote carefully, you will know that the 1min is for the SV105 and SV205 camera. You can check again.

You made some really good points there. I checked on the net for more information about the issue and found most individuals will go along with your viuews onn this site. туры в дубай из москвы дубай погода по месяцам дубай мечеть
