How do you autoguide a telescope?
Autoguiding is accomplished by sending small corrections to your telescope mount via an ST-4 cable communicating from your guide camera to the mount. You can also autoguide using the pulse-guiding method that utilizes a direct connection from your PC to the telescope mount.
How do you autoguide with PHD2?
Using PHD2 Guiding
- Hit the loop button and look at the available stars, adjusting focus if necessary. Move the mount or adjust the exposure duration as needed to find a suitable guide star.
- Click the ‘Auto-Select Star’ icon to choose the best guide star candidate.
- Press the PHD2 Guide button.
Do I need an autoguider for astrophotography?
No, there is no need. Guide cameras usually guide on stars at or near the center of the field of view where the image is good enough with just about any guidescope.
What is an off-axis guider?
What is an Off-Axis Guider (OAG)? An off-axis guider (OAG) sends starlight to your guide camera using an internal pick-off prism that collects light running off of the telescope axis. An OAG allows you to utilize your primary imaging camera and telescope for autoguiding, without the need for an additional guide scope.
What is a telescope autoguider?
An autoguider is an automatic electronic guidance tool used in astronomy to keep a telescope pointed precisely at an object being observed. This prevents the object from drifting across the field of view during long-exposures which would create a blurred or elongated image.
What is a Celestron autoguider?
The NexGuide Autoguider from Celestron is a stand-alone system that eliminates the necessity of tethering it to a laptop computer for finding or tracking your celestial targets with a motorized alt-az or equatorial mount. A Aptina MT9V034C12STM CMOS sensor allows the tracking of even faint stars, and the larger 5.6×4.
What is a Celestron Autoguider?
What does PHD2 stand for?
PHD2 is telescope guiding software that simplifies the process of tracking a guide star, letting you concentrate on other aspects of deep-sky imaging or spectroscopy.
Do I need an auto guider?
Even if you get a perfect polar alignment, periodic error is still an issue. Your cge-pro will have lower periodic error than many mounts, but so does my Mach1 and I still autoguide. So unless you are imaging with a very wide field or want to stay with shorter exposures, I would say yes you need autoguiding.
Why do you need a guidescope?
The guidescope is a small refractor or even a modified finderscope that is mounted along with the imaging telescope and camera and its job is to capture an image of a single star using its own small camera and then to analyse the movement of that star in the field of view using guiding software.
Can you use an OAG with a DSLR?
I contacted them, twice, they answered that it’s not compatible with dslr.
What is an equatorial telescope mount?
An equatorial mount is a mount for instruments that compensates for Earth’s rotation by having one rotational axis, the polar axis, parallel to the Earth’s axis of rotation. This type of mount is used for astronomical telescopes and cameras.
What is off-axis guiding with the ioptron skyguider pro?
Off-axis guiding with the iOptron SkyGuider Pro. What is an Off-Axis Guider (OAG)? An off-axis guider (OAG) sends starlight to your guide camera using an internal pick-off prism that collects light running off of the telescope axis.
How does the Celestron off-axis guider work?
The Celestron Off-Axis Guider uses a prism to intercept a small portion of the telescope’s focal plane (outside the field of view of the main imaging camera) to locate a guide star. Any movement seen by the guide star will be the exact same movement seen by the imaging camera.
What makes a good guide star telescope?
Providing a large 12.5 mm prism that can be adjusted to move closer to the center of the telescope’s focal plane, depending on the size of the imaging camera. This results in brighter guide stars, with the help of the large prism to fully illuminate the autoguider sensor. Featuring a high-quality, fixed-orientation Helical focuser.
Why is my autoguiding not working with my telescope?
Any flexure in the telescope focuser or optical tube will create a mismatch between your autoguiding system and your imaging train. Those using a compact refractor with a secure and robust focuser likely won’t have this issue, but a large Newtonian with a stock focuser might.
