Re: SharpCap 4.0 - Low FPS

Hi Robin, had it set to mono 8 and down to around 4m/s, didn't make any difference if I set exposure all the way down and I had USB speed all the way up. I've now managed to get it on USB 3 as I've a new desk top PC and I've transferred Pixinsight, PhotoShop and some other bits of software to that f...

SharpCap 4.0 - Low FPS

Hi all, I've been using my ALTAIR290M3 with version 3.2 and getting high FPS and it uses the USB3 quite happily. I've downloaded version 4 and the camera goes straight to USB2 with FPS of single figures or just over 10. I used both versions today in the same session, I ended up just using version 3....

Re: Low Frame Rate with Altair 183C v2

Hi Robin, Thanks for looking at that and it explains quite a lot. I remember a solar session when I used SharpCap and AltairCapture on the same features. I managed to use the "high" FPS in Altair capture and the detail looked nothing like the same capture at a "lower" FPS in Shar...

Re: Low Frame Rate with Altair 183C v2

Hi Robin, thanks for the help and I'll contact Altair. One additional point, I had another check in Altaircapture for FPS. If I start live stack at 5440 x 3648 I hit 17 fps, if I then reduce the resolution to those tested it hits 35 fps at 1824 x 1216 and remains at that for all the others. If I sta...

Re: Low Frame Rate with Altair 183C v2

Hi Robin,

I'll do as you suggest and report back. One observation, your settings are USB speed 3. I'm assuming that's the setting in SharpCap? If so my highest setting is 2.

Cheers

Re: Low Frame Rate with Altair 183C v2

Hi Robin, thanks for the reply and after performing the test you suggested it appears I don't have a write to disk problem. The number of frames remained low and even when it went it up (on the 290M) they were buffered and saved. I did this on the 183C and the 290M, the 183C didn't buffer no matter ...

Re: Low Frame Rate with Altair 183C v2

Hi, to continue asking a few more questions on this. I've since increased my RAM to 16GB and dug around the laptop specs. It has a WD Blue 2.5" (2004) 1TB HDD with a AMD A6 - 9220 processor. The latest speed test in SharpCap yields 78Mb/s, I'm now thinking of changing the HDD to a 500GB or 1TB ...

Re: A brief introduction to the SharpCap Sequencer

Hi Robin,

First go today, I've selected the Gain Value block but cannot set a value don't know if it's me or not!

I've also not spotted anywhere to set USB speed, is there one?

Cheers

Re: Low Frame Rate with Altair 183C v2

Hi Dave,

Thanks for taking the time to look at this, I'll probably try another cable as it's cheaper than another camera! If I do buy another camera I'm going to connect it to my laptop before I buy it in the shop!

Cheers
