What is an ST-4 port?
Some computer controlled telescope mounts have an autoguiding port that connects directly to the autoguider (usually referred to as an ST-4 port, which works with analog signals).
What is the Celestron Auto Guide port?
Find out with our basic guide to autoguiding. The autoguider captures regular snapshots of the sky and a computer compares them to detect star drift caused by the apparent movement of stars across the night sky, issuing corrections to the mount via a cable attached to the autoguide port to keep the mount on track.
Is an ST4 cable the same as a phone cable?
ST-4 interfaces use a modular-style connector and jack similar to telephone cabling, but they are different. Telephone cabling is referred to as RJ-11 and it uses four wires, and a six position connector that only has contacts in the middle four positions.
Can you autoguide without a computer?
The SynGuider – stand alone Autoguider can guide an equatorial mount without the help of a PC/Laptop, improving productivity during astro-photography sessions, helping you to obtain perfectly round stars during long exposure times. Supplied with guiding handset & cable, serial cable and battery pack.
How does ST4 Autoguiding work?
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.
Can you use an Autoguider in Alt AZ?
Technically, yes, it will work. Many modern autoguiders can keep up with the guide rates involved.
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.
Do I need an Autoguider for astrophotography?
Overview – The Need for Autoguiding A good equatorial mount is a must-have for astrophotography. These errors are more pronounced in mid-range equatorial mounts than in more expensive mounts, but even the finest mounts available to amateur astronomers will face these tracking imperfections.
Who designed Asiair?
Not only that, but the the PI4 has 4 GB of RAM. This, coupled with the new CPU, means that the Pro version is 30% faster than the PI3. When it comes to slot and port positions, ZWO has designed the ASIAIR Pro so that the M4 and 1/4″ opening on the bottom and side of the body are symmetrical.
Do I need Autoguiding?
Autoguiding is only necessary when taking exposures of at least 30-60 seconds. If you’retaking short images or video clips of bright objects like the Moon or planets, or you’re taking sub-frames (‘subs’) of deep-sky objects of less than 30 seconds, you may not need to guide during your images.
Can you guide an alt az mount?
The guide camera must rotate with the imaging OTA. You cannot guide through a guide telescope that is mounted elsewhere on the alt-az mount (not rotating on the rotator) When you guide an alt-az mount (with or without rotator), the guide software must be set to handle both axis as normal tracking axis.
What is a telescope rotator?
The telescope rOTAtor rotates the entire Optical Tube assembly OTA. This means that any equipment installed on the OTA is rOTAted too. Therefore you can use a piggybacked guide telescope for guiding or take long exposure images with telephoto lenses mounted on top of the OTA.
