(1) The motor (left) side part of the shaft adapter is .625" aluminum rod with a 5mm center bore and set screw to secure the motor shaft. When enabled, on Run will try to measure the focuser backlash. I'm curious why you can't get the coupler over the flat on the shaft? I have a Pegasus Focuser and Run Nina B13 (b14 just came out). If your scope has external focuser you can measure it easily. Using a CCD or DSLR camera can be done, just get the right T-adapter for your DSLR and possibly a Barlow lens to get . With this optical design, the guider camera is looking through a 'tilted window' and this causes a slight but useful distortion of the guide star image. I think maybe I need to decrease the step size a bit? The book is illustrated with more than 150 color photographs and includes a full table of contents and index. FocusMax is routinely used worldwide with unattended, all-night robotic-telescope operations including, asteroid and supernova searches, astrometry, photometry, astro- imaging, and more. Over the years, my work has been published, awarded, and shared widely. The new Auto Focusing Aid that comes with APT 3.88 and later is combined effort of Stephen King, Benjamin Schulz, Jim Hunt, Ivaylo and Maria Stoynovs. and looked up the software´s autofocus routine. This is very important value and depends on the, Default value: 35. We provide manual and fully automated options. Stephen suggested the method of hyperbola fit for finding the exact focus point by exploring a range of data points and made the "prove of concept" tests. Focuser: ZWO EAF The horizontal is the focuser position, the vertical is the measured HFD/FWHM. FocusMax was designed to aid astronomers in the difficult task of focusing CCD-based telescopes. APT user also trying out NINA because of the auto focus. Don't know what your current software suite consists of, but if looking for a complete imaging suite, SGP is a very efficient and cost effective solution. 1. That comes to a total price of just £415 (without . APT gives way to calculate the CFZ measured in microns. I have no knowledge of 3D printing though. Credit: ZWO. Allows speeding-up the image download by reading part of the sensor pixels. Camera: ZWO ASI 183MM pro As such, it does not include any kind of physical remote controller. Askar ACL200 lens is specifically designed for astrophotography. The IR Pass filter is what we would traditionally open our cameras up to remove.

Lunt LS80THa/B1800FTPT/DSII. Carl Zeiss Distagon 35mm, Carl Zeiss Otus 55mm. For example, nina stops guiding when focusing and as a result my object drifts across the field of view over the course of the night. • Can be used in both autofocus and manual modes. In other hand if we move with step much smaller than the CFZ we will get very small changes in the HFD/FWHM readings and usually these changes will be affected by the atmosphere turbulence. Switching back to the sii filter with the binning, I tried again...and success! by DeepSkyDad. At the end the calculated offset will be reported and you can apply the values in the. Found inside – Page 3If you are using an autofocus SLR camera or an autoexposure camera , if possible , set the focus and exposure manually . Automatic focus and automatic metering generally do not work well for astrophotography . Star Trails . My guess is that this has something to do with the Sii filter and that I may need way longer exposure times. I image with N.I.N.A. A popular DIY ASCOM focuser with more than 106,000+ downloads. ZWO offers unparalleled, one-of-a-kind innovations for astrophotography cameras and accessories.Browse through a wide variety of CMOS cameras, ideal for deep sky, widefield and planetary imaging. Building from the framework that is the Canon EOS R - a full frame mirrorless camera - Canon decided to re-enter the astrophotography camera scene again and have announced the Canon EOS Ra. The default value is 1. And how are you attaching everything to your mount (in my case it would be to a Star Adventurer).

Astrophotography is an exception to this but then it's also a more specialised area of photography. zoom lenses the maximum ... Too small, and the star HFR analysis might not be able to discern a meaningful difference between two successive frames or be able to "see" past poor seeing. NINA error message "mount driver needs valid epoch", This is not recommended for shared computers, Zenithstar73-Which screes need to be loosen? It's hard work: it takes practice and proper equipment, and it will take you quite some time and effort to become good at it. I was recently selected to be a part of a program in which ZWO recruited astrophotographers to be "Experience Officers" who are to test and review a device called the ASIAir Plus. Either way, you gain control over your entire astrophotography setup. Our True-2™ UltraWide Adapter is a true 2" prime focus adapter that takes you directly from the bayonet mount to a 2" barrel with as few wasted photons as possible, adding as much as 10mm additional clear aperture over legacy adapters! Another thing you can do if your getting a poor V curve is to set it to take two images for each point. Autofocuser, drawtube-focuser clash considerations in N.I.N.A. SGP has a good autofocus routine built in (though it does struggle with Globular Clusters, but that's a whole different thread.!). Previously owned: Coronado ST 70/400 SolarMax III BF10 (0.7Å Hα) Imaging cameras: ZWO ASI 1600MM Cool. Defines the default ISO for auto-focusing. It may also be relevant to point out that a couple days ago the motor shaft came loose from the coupler attaching it to the telescope focuser. I am using the 76mm ZWO camera clamp at the back of the camera and a 50mm guide scope ring just infront of the filter wheel. Which ones have you tried to autofocus with? Either way though things are working now so I’m not gonna ask questions. Fits ALL Nikon SLR & DSLR Cameras. Use night with stable atmosphere and star or area well above the horizon. Keep in mind that all scopes (even my F/2 RASA) will have a small zone where the focus is as small as it's going to be. I've since switched from NINA to Kstars/Ekos so that I could run my rig semi remotely, but I used the following settings with great success: From those settings you may want to tweak the backlash depending on how everything works for you, as well as the crop ratio settings if you don't have circular stars all the way to the edges. I decided to switch to the oiii filter and I got a reasonable curve and focus, but still not as successful as before. Before you start measuring the focuser's backlash make sure that you have disabled all features that can cause unwanted motor movements. Forget having to haul your heavy equatorial mount far from home. $84.99. Think of step size as a sampling rate. Image of Jupiter taken with a Celestron C14 at f/27. This tool is an electronic focuser that enables precise and dynamic focus control during sessions of planetary and deep-sky imaging. It should work for well with 12, The button Auto calculates the Focuser Move Step based on. You can then multiple that % miss by your backlash and use that to tune in. Additionally, I have found the following settings to be helpful. It is specially designed to fit on all Schmit-Cassegrain telescopes. This is exactly what I was wondering! It's a very well made piece of equipment in comparison to the Lakeside controls I was using before. Select a comet from the object guiding catalogue, point your telescope, and start photographing.

The Astrodymium Ring System is an all in one mounting & autofocusing solution to using the popular Samyang/Rokinon 135mm F2 lens for astrophotography.. With the included autofocuser adapter, and a ZWO EAF, it will be possible to electronically control the focus on the 135mm lens, which allows you to automate your imaging sessions. . Several colors forms are used to display various data: - dots are used to display the data from the first pass, - small rings used to display data from the second pass, - small squares are used to display data ignored via backlash detection, - purple dots / rings are the data used for hyperbola fit, - red dots / rings are the ignored post ions not for hyperbola fit, - green line is the position of the hyperbola minimum. The Standard EAF works with all capture software that is supported by the ASCOM platform. We use cookies to ensure that we give you the best experience on our website.

Play around with the step size such that the first measurement that NINA takes ends up being around ~2-2.5 times +/- the lowest measurement. When enabled, will store the results of all successful focusing runs in log file. You have to make a bit bigger second move in order to compensate the backlash. So if NINA's best focus is an HFR of 3, then you want your highest HFR point up around 6-8ish.
