{"product_id":"celestron-m42-spacer-ring-kit","title":"Celestron M42 Spacer Ring Kit","description":"\u003cp\u003eCelestron’s M42 Spacer Ring kit includes three different length spacer rings to achieve the proper back-focus distance with our popular Celestron optical tubes and T-thread camera adapters. To achieve the best astroimages, it is important to attain the proper back-focus distance for your camera relative to the telescope it is being used with. If the back-focus distance your camera consumes is not exact, the performance at the corners of full-frame imaging sensors will suffer—stars will appear elongated and not as pinpoints.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eHow to Use\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eDepending on your method of astrophotography (DSLR or CCD\/CMOS), there are two ways to use the M42 Spacer Ring. If you are using a DSLR, place the desired M42 Spacer Ring between your T-Ring and your T-Adapter for your optical tube. If you are using a CCD or CMOS camera, place the desired M42 Spacer Ring between the camera and the T-Adapter for your optical tube.\u003c\/p\u003e\n\u003ctable height=\"180\" width=\"534\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 170px;\"\u003e\u003cstrong\u003e Spacer Ring Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 348px;\"\u003e\u003cstrong\u003eWorks best with:\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 170px;\"\u003e7.5mm\u003c\/td\u003e\n\u003ctd style=\"width: 348px;\"\u003eProvides proper spacing with RASA 8 for many ZWO cameras\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 170px;\"\u003e\n\u003cp\u003e12mm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 348px;\"\u003eProvides proper spacing with RASA 8 for many Atik cameras\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 170px;\"\u003e30mm\u003c\/td\u003e\n\u003ctd style=\"width: 348px;\"\u003eConverts ZWO camera w\/filter slider to 55mm back-focus standard for use with Schmidt-Cassegrain \u0026amp; EdgeHD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe M42 Spacer Rings are machined aluminum black anodized.
