determine any star’s OBAFGKM star type and temperature from its spectra curve.Notice that the red curve has dips exactly where the blue lines predict: The blue calibration lines show where we’d expect to see dips due to the star’s Hydrogen absorbing light. The red line is an intensity graph of the star’s spectrum. This spectrum was displayed in real-time with our RSpec software. The observing location for this spectrum was just 4 miles from the center of a large metropolitan city. Your FITS or DSLR camera would, of course, be even more sensitive. We’re happy to coach you on how to acquire these skills: contact form link.īelow is a real-time view of the spectrum of Vega made with a Star Analyser, an 8″ SCT, and just a $50 webcam. If you don’t have those skills, you will need to acquire them before successfully using a Star Analyser. And you will need to be able to point your telescope at those stars and capture images that are properly exposed, well-focused, and not smeared by star-movement through the sky. This means you will need to locate specific stars in the sky. Note: To use a Star Analyser grating, you need to capture images of deep space objects. We have gratings in stock and we can ship you one today - see our online store: link. We have customers using these gratings on webcams, DSLRs, modern video astronomy cameras, and of course FITS images from cooled or uncooled astronomical CCDs. to capture and understand the spectra of stars! With our gratings and software, it’s amazingly easy. The grating is durably mounted in a standard 1.25″ filter cell and is protected on both sides with anti-reflection coated glass. The $195 Star Analyser 100 is a diffraction grating with grooves that are spaced at 100 lines/mm. The video below shows some exciting examples of what you can do with a Star Analyser:Īlso, check out our samples page ( link) for some great sample work done by amateur spectroscopers. Capturing the spectrum of a star is easy! Use our grating, a DSLR or small telescope, and our award-winning software. It can be mounted on your telescope just like any other 1.25″ filter. It’s is easy to use and works with most cameras. Our Star Analyser 100 (SA-100) grating is designed specifically for amateur astronomical spectroscopy. So if you want to buy from them, make sure it is absolutely 1000% going to work for your setup, otherwise you might lose a few hundred bucks on a return.The Star Analyser 100 grating screws onto your camera nose or filter wheel But there's plenty of other shops out there like Starizona who will accept a returned item, no questions asked. Not sure how this is possible considering I never even attached the camera to my guidescope. When they got the item back, even though i had never used it, they claimed it had shown signs of "wear" and added the restocking fee. I tried to return an ASI 290mm in exchange for an ASI 174mm. For instance, you can't be sure that your guide camera/scope can work with your setup. However in astronomy, a very technical hobby where items don't always work, returns are often needed. I understand smaller shops have to compensate for lost $ with opened items. This is a problem, especially if you're buying very expensive items, that 10-20% restocking fee can quickly add up to hundreds of dollars. They also charge 10-15% above market value on amazon to compensate for amazons cut. On amazon, they will slap on a restocking fee even if you returned the item unopened. However, they do NOT like when you return things, and will often slap a 15% restocking fee onto whatever you returned, no matter the condition. Items were shipped quickly and they were very efficient. The first several times I bought from them, I had 0 problems. They seem to be a popular vendor on Amazon as well as in the astronomy community. Just wanted to warn everyone about buying from Agena Astro.
