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.
What is PHD2 software?
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. Easy-to-use, “push here dummy” guiding for beginners. Sophisticated guiding and analysis tools for experienced users.
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.
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.
What is the purpose of autoguider?
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.
How do you do Autoguiding?
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.
Does PHD2 dither?
‘Spiral mode’ – tells PHD2 to dither with fixed-size amounts in a clockwise spiral pattern. This can be a good choice when the imaging camera has significant fixed-pattern noise or the mount has a troublesome amount of Dec backlash.
How do I connect 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.
What is the purpose of Autoguider?
How do you autoguide a telescope?
What is an off axis guider?
An off-axis guider is a T-shaped camera mount. One short arm of the T threads onto the rear cell of Schmidt-Cassegrains or slips into refractor or reflector focusers. The off-axis guider allows you to guide your telescope through the same optics that are taking the picture.
What kind of software can I use to AutoGuide a telescope?
By using autoguiding software such as PHD2 Guiding, our computer can communicate with the telescope mount. PHD2 Guiding is the successor to PHD Guiding, which I used for several years before upgrading to PHD2. PHD stands for “Push Here Dummy”, and it very easy to use, once everything is set up properly.
How to use the starshoot autoguider on a telescope?
“The StarShoot AutoGuider (SSAG) could not be simpler to use…. Insert the SSAG in the guide scope, connect its USB cable to your computer, and the RJ-12 cable to the guide port on the mount and you are ready to go.
What do you need to start autoguiding astrophotography?
What you need to start Autoguiding. The basic equipment needed to accomplish a successful night of astrophotography with autoguiding is a secondary telescope (guide scope) and a guide camera. The guide scope rides atop your primary imaging telescope and is usually much smaller.
How to AutoGuide a telescope for deep sky astrophotography?
My Process 1 Attach 60mm Guide Scope to finder shoe of the primary imaging telescope 2 Install Altair GPCAM2 camera to the guide scope 3 Connect camera to computer via USB 2.0 A-male to B-male cable 4 Start PHD2 Guiding and Connect to Camera and Mount 5 Slew to your deep-sky target, center, and frame using APT
