That is only possible with Ascom or tracking.
I only have Dobsonian telescopes that can be moved manually.
So the point is that I can only hold the planet in the entire field of view of the camera, but without ROI I have very few fps.
With ROI I have high fps, but manually can't manage to keep the planet in the field of view.
Hence the desire for a ROI that moves with the planet in the entire field of view of the camera.
I don't know if and how it works, but since you can already center the planet within the image, it should also be possible to tell the ROI to move throughout the camera's field of view so that the planet stays in the ROI.
Is that possible?

Re: ROI suggestions
Given your setup I don't think that is currently possible for you, and I am not sure it would be possible or at least practical to do without a tracking mount. If you're tracking, at least you have some time for the ROI to move around in the sensor. Without tracking, it would fly off the sensor pretty quickly, depending on your magnification
Re: ROI suggestions
That's why I'm asking here if it's possible.
I can manually track the Dobsonian without any problem so that the planet remains in the entire field of view of the camera sensor, that is no problem.
But I always have to operate the camera in full resolution - Sharpcap centers the planet in the image.
But the fps are very low.
Therefore it would be great if you could shoot with a small ROI and the program would move the ROI field with the planet. Of course, this only works as long as the planet is somewhere on the camera chip, but that would be enough.
You would have to tell the ROI, so to speak, to move to the right as the planet gets closer to the right edge of the ROI, or up as it gets closer to the top edge, and so on.
Whether this is feasible I don't know. But it would be great for filming planets with telescopes without tracking like Dpbson telescopes to use a small ROIs with high fps.

Re: ROI suggestions
Mario you may want to start a new post on this topic to get better attention
Basically you want ROI tracking without connecting to a mount
In the bigger picture, your best solution is to get a tracking mount

Re: ROI suggestions
Thanks!
Tracking mounts for 20'' and bigger dobsonians are very expensive.
Especially with Ascom and/or guiding and in europe.

Re: ROI suggestions
Hi folks,
yes, you can do this - try the following...
1) choose a smaller ROI and get the planet in view
2) Choose 'feature tracking (experimental)' from the tools menu
3) Choose 'Use camera ROI' for movement and 'Use center of mass' for tracking.
4) Press 'Monitor' to start tracking the center of the planet, then 'calibrate' then guide.
SharpCap should now track the planet by moving the ROI. However, I just tested this and can't get calibrate to do anything, so maybe there is a bug there - I will check.
cheers,
Robin

Re: ROI suggestions
Hello Robin,
thank you very much!
I have now tried it once with a simulated (very bright) planet during the day in my dark basement and it did not work.
I always get only the "Low contrast warning".
Please have a look at the video, if I would have done everything right.
But I will try it directly on a planet as soon as I have a clear sky.
CS, Mario

Robin in my experience when i've attempted this, it does not work unless the mount is first connected. If you can remove that requirement, that would be great!
Re: ROI suggestions
Hi Robin
Back to managing ROIs, when choosing "custom" is it possible to at least set the dimensions in the dialog box to the current ROI? It would make editing it a lot easier
thanks for considering!

Re: ROI suggestions
Hi Brian,
if you choose the option to use the camera ROI to make adjustments then there is no need to have the mount connected. Of course this will run out of ROI offset ability at some point, but is much simpler and does not require calibration (you need to press the calibrate button, but it does nothing except enable 'guide'). Note that there was a bug with this option, fixed in today's update.
