The Orion 0.8x Imaging Focal Reducer's fully multi-coated, 38 mm clear aperture optics are housed in a sleek, all-machined, anodized aluminum body. Internal glare-threads provide maximum image contrast and brightness. It is ...
What is a focal reducer for a telescope? Focal Length of a Telescope: In general, the longer the focal length of a telescope, the smaller the section of the sky it is able to see. This is ideal when looking at distant, dim objects, but makes it difficult to view larger objects such...
Unfortunately, no. The Antares f/6.3 SCT reducer is actually a reducer/corrector, meaning it works to correct the coma and curvature inherent in SCT images. As the ACF design you have already corrects for coma and partially for curvature, using this reduc" Yes, I seen the same thing when ...
We describe the scheme and design features of the new IFU unit (Integral Field Unit) meant to perform integral-field spectroscopy as a part of SCORPIO-2 focal reducer, which is mounted in the prime focus of the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of...
No, I don't have a DSLR. Do you have an example of a quality reducer for a Newtonian? It gets very expensive. Paracorr 2 Explore Scientific Starizona Nexus I own the Starizona Nexus, it works 100% but also cost nearly as much as the Newtonian telescope I'm using it with. ...
What is a focal reducer for a telescope? What is the focal plane of a telescope? What kind of spectra does a Hubble Telescope have? Is the Hubble Space Telescope an x-ray telescope? What is the diameter of the James Webb Space Telescope?
I could have used a 0.7x reducer and gone down to about f/5 and reduced imaging time by half, but I really wanted the additional detail in the image so I stuck with my f/7 for the additional focal length. I'm not sure where you're located, but your available time is going to ...
52 (1986). The experience gained with EFOSCtype instruments at the 3.6-m telescope and at the Nl7 then led ESO to propose in the VLT Instrumentation Plan of June 1989 the construction of two dioptric focal reducer/low dispersion spectrographs for deep-imaging, low-resolution and multi-object...
