Quick links. What I'd like to do now is to take advantage of Sequence Generator Pro auto-focus feature. Is it possible to use SGP auto-focus within Sharpcap features, I mean using Sharpcap for images capturingprocessing and live stacking, and using SGP in the same time for auto-focussing?
Any help appreciated.
What’s New in SharpCap 3.0
If you absolutely must have fully automated focusing, then you'll need to switch between programs disconnecting and reconnecting the camera accordingly.
If not, you might also find semi automated focusing in Sharpcap to be more to your liking. Give it a try and see for yourself. I'll follow your advice and try Sharpcap semi automated routine next time.Hobby resin casting
If there is no other solution than switching between programs, which means disconnecting and reconnecting the camera, this is something I really do not want to test while imaging! I've tested it back to back and get pretty consistent results vs my mask.

I hope in a future version you can auto select go to best score or position so it will automatically finish. Also a pre-selected start value so it will start without moving the focuser to a specific location. If focus is around steps have it know to start around for example.
I believe the next version of SC will be set up to have sequencing I suspect the focus routing might have more options. Now the best would be that the next version of SC would integrate a full automatic focusing feature, as the step seems not so big to implement it! Also a pre-selected start value to avoid having to move the focuser to a specific location, as suggested by Chongo Robin please, what's your position about this question?
I suppose that taking the ideal starting position a bit further might help — if the focus position was limited to a band of values that the user configured then autofocus might be more reliable — basically in the configuration you would set up that the best focus point was between and and that would give SharpCap both a good starting point and an idea of what range it should be looking within.SharpCap is an easy-to-use and powerful astronomy camera capture tool.

Flexible File Naming.SharpCap 3. The use of an orange colour for text and controls instead of the more traditional red makes text legibility much better without adding significantly to the screen brightness. You may notice that a couple of things are not changed into a dark colour scheme — in particular scrollbars and the window title bar.
This has been quite a popular user request — the ability to show all the controls on one monitor and show just the captured image on a second monitor. As you can see below, two monitor view is particularly helpful in Live Stacking mode because it allows room for the various Live Stack control and information tabs to be split up so that more than one is visible at a time.
It also has a pair of testing simulated cameras that can be used to try out the features of the program on cloudy nights. The Folder Monitor Virtual Camera adds another way to get images into SharpCap — it can read existing or newly added image files from a directory opening up new ways to use SharpCap.
As a couple of examples:. The resolution and colour space values are also determined by the contents of the image files being loaded and cannot be changed. Additionally dark subtraction and flat frame correction can be applied and the frame rate limit can be set. Image files are always processed in date order starting with the oldest first.
The resolution and colour space values are selected from the first frame processed, and files that have different resolutions or colour space settings will be skipped.
If SharpCap runs out of files in the folder or if there are no image files in the folder initially then it will wait for new image files to be added and load them when they appear. Many EAA Electronically Assisted Astronomy enthusiasts are now keen to run their entire imaging session within a live stacking tool such as SharpCap — they are also often keen to avoid any post-processing in other applications. The Gaussian Blur noise reduction and Unsharp Mask sharpening are basic tools which you would find in most image manipulation applications.
They are relatively quick to calculate. With careful adjustment of the parameters, these simple tools can suffice to give useful image improvements in many cases. Bilateral Filter noise reduction which can lower noise with less blurring effect than the Gaussian Blur option. This tool will tend to remove noise within areas of similar colour without blurring an area of one colour into an adjacent area of another colour.
The radius option selects over how large an area in pixels the smoothing is effective while the luminance tolerance specifies how different colours have to be for the algorithm to try to preserve the differences between them. Setting the luminance tolerance too high will make this algorithm give results similar to the gaussian blur option. Weiner Deconvolution is an advanced image sharpening algorithm that uses an estimate of the PSF point spread function of the image to try to correct for blurring introduced by optics, seeing and stacking.
The estimate of the PSF is calculated from the shapes of detected stars in the stacked image so this sharpening feature will only work for images containing stars. Note that both of the advanced algorithms require more computation than the simple ones, so using a fast PC is advisable, particularly for high resolution cameras.
Like the white balance controls, saturation adjustment is a SharpCap Pro feature.Privacy Terms. Quick links. Focuser mod to improve Sharpcap Autofocus Anything that doesn't fit into any of the other forums. I have found that the friction is not perfect even after adjustment and during the course of an evening there is always a small amount of slippage within the mechanism. This is compounded when using the autofocus in Sharpcap with multi star FWHM in my case as the calculated position may not be correct when Sharpcap moves to it due to this random slippage.
To create a more absolute repeatable process for the focusing I have made a ball screw focuser drive, this is controlled by my original sesto senso focus motor. I machined the ball screw so that the shaft runs through a bearing block which the sesto clamps to between the sesto shaft and the ball screw shaft I have a flexible coupling to deal with any slight misalignment.
The brass thumb wheel allows manual movement when the sesto is not powered Tonight we tried it for the first time on actual stars using the autofocus routine and I had a nice focus curve from out of focus through focus and back out of focus and the move to best position command worked flawlessly so I will now be using this method of focusing in future, and also plan to use it to work out the offset positions between filters and also assess thermal movement in relation to atmospheric temperature change to get an idea of refocusing intervals.
You do not have the required permissions to view the files attached to this post.You can use the tool to measure your polar alignment accuracy without having a SharpCap Pro license, but with a Pro license you will be able to see live updates on screen showing the current polar alignment error as you adjust your mounts altitude and azimuth.
New in SharpCap 3. Planetary and Lunar images will benefit from using live flat frame correction too as it eliminates dust donuts caused by specks of dust on the sensor, camera window or filter.
Of course, you can use the flat frame correction feature while deep sky imaging in SharpCap too — for example while Live Stacking to correct for uneven illumination of the sensor due to vignetting.
Not only will SharpCap apply flat frame correction to every frame that comes from the camera, it will also assist you through the process of capturing a master flat frame by capturing and averaging a series of flat sub frames.
Dark subtraction is another feature, like Polar Alignment, that has been improved in SharpCap 3. Just like the flat frame creation tool, SharpCap has a dark frame creation tool that will help you create averaged master dark frames and store them in a dark frame library. Previous versions of SharpCap had a range of tools to help measure the quality of focus of the image to assist with focusing and accurate focusing can be one of the hardest parts of Astrophotography.
Now in SharpCap 3. The first new feature is the ability to make SharpCap perform an automated focus scan over a user-definable number of steps. The result will be a graph — like the one shown below — showing how the focus varied with the focuser position.
These buttons are the second focus related SharpCap Pro feature and they take care of getting back to the best focus position for you and making sure to approach from the same direction used for the scan to avoid backlash issues. In SharpCap 3. Some examples of scripts that have been written by SharpCap users include automation for all-sky cameras, automation of filter wheels for LRGB planetary imaging, automatic image capture with text labels being added to each image after capture and automation of eclipse observing sequences.
Ever wondered whether you are using the right gain or exposure when deep sky imaging? Whether 6x ten minute exposures really do give you more detail than 12x five minute exposures? In combination with the results of Sensor Analysis see belowSharpCap can measure the sky background brightness for you and then perform a mathematical simulation of the impact on final stacked image quality of using different gain and exposure combinations.
You can also see graphs showing the impact of using longer or shorter exposures or lower or higher gain than suggested. An initial calibration step must be performed so that SharpCap can learn which way and how fast the image moves for the various mount movement directions. Feature Tracking is currently experimental — please feel free to test and report any issues.Vott yolo
More feedback on the performance with different mounts and focal lengths is welcome. This is a new application of the image quality measurement techniques that SharpCap has provided to assist focusing for some time.
Instead of helping you find the point of best focus, you can now use the image sharpness measurements to help you capture the moments of clearest seeing without having to sit with your eyes glued to the computer screen at all times. Launched from the Tools Menu, the seeing monitor shows a chart of the recent range of image quality with the most recent values highlighted.
This gives a much more objective measurement of when the seeing is good. An option to run stacks using a sigma clipped algorithm is available to SharpCap Pro users. Sigma clipping helps keep rogue pixel values out of the stacked image — for instance aeroplane and satellite tracks can be much reduced or eliminated by the use of the sigma clipping algorithm.
The mini-histogram and live stack histogram both have auto-stretch buttons which analyze the current frame and set the black, mid and white levels automatically to give a good view of the object being imaged. You can even adjust the intensity of the auto-stretch algorithm in the SharpCap general settings page.
