Turn your 50mm finder scope into a Guiding Scope with this helical focuser. The focuser has 50mm threads(same as your guide scope) on one side and regular 1.25″ eyepiece holder on the other. It has brass compression type tension so it won’t mark your camera.
In the same way How do you improve guiding accuracy?
10 Quick Tips on Guiding
- Polar align. Accurate polar alignment is an essential part of guiding. …
- Don’t overload your mount. …
- Check your connections. …
- Watch out for vibrations. …
- Brightest isn’t always best. …
- Don’t be afraid to defocus. …
- Don’t overcompensate. …
- Try guiding in just one axis.
Subsequently, What does an equatorial mount do? An equatorial mount is a mount for instruments that compensates for Earth’s rotation by having one rotational axis parallel to the Earth’s axis of rotation. This type of mount is used for astronomical telescopes and cameras.
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 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 good guiding astrophotography?
Several factors and trade-offs make for a good guidescope for astrophotography including: A sufficiently large aperture to detect faint guide stars in a nearly any field of view anywhere in the sky and to minimize autoguider exposure time, yet a small enough size and weight to prevent taxing the mount.
What is PHD2 guiding?
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.
How do you use PhD guiding?
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 does AZ mean on a telescope?
ALT / AZ. Alt Az (short for altitude-azimuth) is the simplest of all telescope mountings. It’s designed to allow the telescope to point up and down and left and right.
What is a SkyWatcher mount?
The SkyWatcher Star Adventurer is a user friendly modular mount designed for wide field astrophotography and time-lapse photography. … It is a precise, portable and stable celestial tracking platform for sidereal, solar and lunar tracking with automatic DSLR shutter release control.
Which is better Alt azimuth or equatorial?
Alt-az mounts are considered superior for visual astronomy because they provide such comfortable viewing positions at the eyepiece. Many experienced visual astronomers recommend alt-az mounts for this reason. All in all, equatorial mounts are designed with the astrophotographer in mind.
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.
Where can I post astrophotography?
AstroBin is the answer.” “AstroBin is by far the most accessible astrophotography image hosting platform around. Regardless of shooting with a DSLR, mirrorless camera, a backyard telescope, or a deep-space observatory, AstroBin is the place to be.”
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.
Can you use an autoguider in Alt AZ?
Technically, yes, it will work. Many modern autoguiders can keep up with the guide rates involved.
How do you focus a guidescope?
– point your main and guidescope to somthing at least a mile away and try focus. Remember the position or put a piece of tape on it, etc. – play with gain and exposure time until you see something at least. The pinpoint or not question depends on a few factor, so I think both may lead to a good result.
How long does it take PHD2 to calibrate?
It takes PHD2 almost 30 minutes to calibrate. Once it does, my guiding is superb. I realize the exposure time effects how long the calibration will take, so I have been keeping exposure time to 1 second while calibrating, and then I bump it up to 2 seconds for guiding.
Does PHD2 have plate solving?
So PHD2 has no use for plate solving. There are free plate solving programs out there.
Where should you calibrate PHD2?
I normally calibrate PHD2 near the celestial equator to the South East at an altitude of around 30 degrees. But I usually pick targets at a higher elevation if I can, where there is less light pollution.
Does PHD2 work on Mac?
1. PHD2 runs on a Mac. Probably the easiest to get working. If your camera and/or mount isn’t directly supported you can use INDI.
What is an ST4 cable?
ST4 guiding refers in part by the type of cable used in most cases and connects to the guide port on the mount from the camera. Usually a phone type cable that goes from the camera to the mount.
Do I need an equatorial mount?
An equatorial mount solves this problem. It can perfectly track the stars as they move during the night, and you only need to adjust one axis. … Of course, if you want to do any long-exposure photography, like longer than a few minutes in a photo, you absolutely have to have an equatorial mount.
What does f10 mean on a telescope?
Wide field telescopes have a focal ratio of f/7 or less. Focal ratio also influences the brightness of extended objects like a nebula or galaxy. For example, a telescope with focal ratio of f/5 will show an image of four times the brightness as a telescope with focal ratio of f/10, all other things being equal.
What does OTA stand for in telescopes?
The Optical Tube Assembly, or OTA, is the main part of the telescope. It gathers light and it’s where the eyepiece and all optical accessories go. The Mount is what the OTA is attached to and is responsible for the how the user aligns, moves, and tracks celestial objects.
