Version and other question

Question

I was able to install the 3.1.16 trial. The documentation (help) is for version 3.0.3. In version 3.1.16 there is the ASCOM Teloscope section. What role does this section have? Does integration with ASCOM for Drift Align Center integrate or Dither? Need another application (PHD for example) for guide or it can to use ASCOM directly?

If I do not have the options for ASCOM Filter and ACOM Focuser yet, which will be done manually yet, will the application work?

If after installing the application on a computer I change my mind and want to install to another I can use the same license? Or do I have to buy another license?
Do we access to updates to new patch's and releases?

Yes, the documentation is getting a bit out of date.

The ASCOM Telescope control was originally added to allow a Premium or Trial user to jog their telescope with the 4 chevron buttons ( up, down, left, right). To my knowledge the Telescope control section does not integrate with the Drift Alignment for automatic centering of the star, but you can use the Telescope section yourself to center the star. However, the Telescope control functionality does integrate with BYE's Imaging to allow you to configure direct ASCOM Dithering (without PHD or MetaGuide actively guiding the mount). You only need to select ASCOM as the Dithering Provider, set the parameters appropriately, enable dithering, and connect BYE to your telescope before starting imaging.

I had thought that there was a way to tell BYE to park the telescope when the imaging plan finished, but I no longer see the control that used to exist for that purpose. I guess that it was removed.

Yes, BYE will work perfectly well without any of the ASCOM functionality enabled/turned on/connected, so you do not need an ASCOM controllable focuser or filter wheel.

The End User License Agreement is installed with the User Guide. This gives you the right to install BYE or BYN on multiple computers, as long as you only use it on one PC at a time.

Downloads are available from the Downloads tab at the top of this page. You must be logged onto the site with the same username that you used to get your Trial or paid license. BYE Version 3.1.17 RC2 is available for download from the Pre-Release section. It has a few fixes, and support for new cameras. It has been available for a few months and seems to be stable.

I hope this answers your questions.

Hello,

Thank you for these answers.

I bought a newton 300/1500 skywatcher with goto EQ6 and a Canon 77D. For now I'm still learning to use them and I'm trying to gather as much information as possible for this hobby.

II believe that positioning on certain stars and galaxies I will be done through Cartes du ciel or World Wide telescope applications that integrate with ASCOM and the synscan drivers for windows OS and for android with SkySafaryPro. (Here you can give me more suggestions if you have)

But for the astrofotografie part I did a software analysis on the market and I try to make the best choice so that I have fewer investments (for first, as amateur). From the analysis I chose the BackYardEOS application. There is also the APT application but I have not been able to test it. (Here you can give me more suggestions if you have)
But for astrophotography is extra autoguider needed? Do I have to buy another camera and finder to attach to the telescope to do this?Can not I use the same camera for autoguider and use BYE as software?
Thanks in advance

In order to have round stars in long exposure astrophotographs, you must autoguide. Autoguiding makes very small adjustments to the mount's position while you are imaging. So in addition to the imaging camera, you must have another camera for guiding. That camera must also be attached to a telescope, but the telescope can be smaller and have a shorter focal length from the imaging camera.

However there is a lot of astrophotography that you can do that does not require autoguiding. Some examples are wide field imaging with a camera and lens piggybacked on your telescope, such as nightscapes; images of the moon; planetary imaging. I am probably forgetting some.

I would suggest that you try some of these other techniques while learning to use your new equipment and also learn about the equipment and techniques for long duration astrophotography.

Hello

Thank you for these answers.

I already have everything we need to mount the camera in the telescope's focus. But I did not know that there was a need for autoguide. I'll try use until I learn how to use them. I ask these questions to figure out what is technically and financially dimensions.
In the BYE application, there are PHD or ASCOM options with which small adjustments are made from autoguides (I'm thinking). What's the difference between them?

The options in BYE for PHD or ASCOM are for dithering. Dithering is different from autoguiding. Autoguiding works while you are imaging to keep the guide star in exactly the same place. Dithering is performed between images to shift the guide star by a few pixels. Dithering is used to help reduce the appearance and to make it easier to remove them during image processing.

When PHD is used to autoguide, BYE can request PHD to perform dithering. BYE can be configured to do this after an image has been captured, but before the next image capture starts.

For Premium (or Trial) users of BYE or BYN, BYE or BYN can also do direct ASCOM dithering. This would only be used when you are NOT using PHD for autoguiding. In this case, BYE sends commands to the mount between image captures to move the mount by a few pixels, just like PHD does.

If you are able to autoguide, then you should dither through PHD. I only mentioned it in my previous note because you asked about integration between BYE and the mount via ASCOM.

As you surely know, the goal of all GEM Mounts is to counteract the Earth's Rotation so that one can accurately and steadily perform Exposures long enough to capture the Dim elements of a DSO.  Much of that ability is based on an Accurate Polar Alignment, and Accurate Movement of the Mount's RA Axis.  Unfortunately, very few Users and their Mounts can provide the levels of Accuracy needed for this effort.  This is where AutoGuiding comes in.  While the Imaging Camera is busy performing a minutes-long Exposure, the Guiding System is taking 1-2 second Images which the AutoGuider software uses to determine small additional Movement Commands that will keep the Target Stars steady for the Imaging Camera.  The AutoGuiding Software is separate from BYE/BYN, and the most common Programs are PHD2 and the older PHD (and Meta-Guide is a 3rd program).

Dithering is different from AutoGuiding - it actually performs a small random movement of the Mount intended to ensure that the Target DSO is moved to different Pixels (allowing for better Noise Reduction during Stacking).  Dithering is associated with BYE/BYN because it is BYE/BYN which requests the AutoGuiding Software perform a Dither with specific Parameters, and makes that request immediately after an Imaging Exposure is Completed and Downloaded, and monitors the post-Dither Guiding Results before initiating the next Exposure.  As you will find in the Settings, BYE/BYN is capable of interfacing with 3x AutoGuiding Programs (PHD2/PHD and MetaGuide and ASCOM-Dither).

Will you want/need to setup and run AutoGuiding??  Yes, eventually.  You can realistically start your exploration of AP Imaging without adding this additional Element.  You'll need to limit your Exposure Lengths (based on your skills at Polar Alignment and the native accuracy of your specific GEM); and that limit will in turn limit the DSOs which you can successfully Image.

You have chosen some significant and capable AP Imaging Gear, and you will eventually (soon?) want/need to add AutoGuiding to that Equipment.  When you do, know that BYE/BYN will work well with that addition.

Hi,

I install new my notebook with all drivers and software (ASCOM, Drivers for may telescope etc.). I try to install BackYardEOS Trial and the section of Ascom Telescope no longer appears ... I hope this is not a problem :( and do the same after buying it.
