SmartCooling also prevents any possibility of overheating by backing off power if the heat sink gets too hot – so you don’t need to worry if your camera is baking in a hot observatory during the day.\u003c\/p\u003e\n\u003ch4\u003eAdvanced Software Included\u003c\/h4\u003e\n\u003cp\u003eAll Aluma CCD cameras come with our MaxIm LT software – a $249 value!  MaxIm LT is a special version of our venerable MaxIm DL software that provides complete control of your camera, filter wheel, and autoguider, plus advanced image processing capabilities.  If you wish you can upgrade to MaxIm DL Pro to get complete observatory integration and even more processing and analysis capabilities.\u003c\/p\u003e\n\u003ch4\u003eIncluded Accessories\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/h4\u003e\n\u003cp\u003eEach Aluma CCD camera package includes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaxIm LT software – please use\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/diffractionlimited.com\/maxim-lt-registration\/\"\u003ethis form\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003eto request your license\u003c\/li\u003e\n\u003cli\u003eDeluxe carrying case\u003c\/li\u003e\n\u003cli\u003eUniversal power supply (110V \/ 220V, 50-60 Hz)\u003c\/li\u003e\n\u003cli\u003e2″ Nosepiece adapter\u003c\/li\u003e\n\u003cli\u003eUSB flash drive containing software, drivers, and documentation\u003c\/li\u003e\n\u003cli\u003e15 foot (4.5 m) USB cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eOptional Micron-Precision Filter Wheel\u003c\/h4\u003e\n\u003cp\u003eThe optional FW8S-Aluma 8-position filter wheel includes a positive centering mechanism that precisely centers each filter in the exact same position every time.

SmartCooling also prevents any possibility of overheating by backing off power if the heat sink gets too hot – so you don’t need to worry if your camera is baking in a hot observatory during the day.\u003c\/p\u003e\n\u003ch2\u003eAdvanced Software Included\u003c\/h2\u003e\n\u003cp\u003eAll SBIG cameras come with our MaxIm LT software – a $249 value!  MaxIm LT is a special version of our venerable MaxIm DL software that provides complete control of your camera, filter wheel, and autoguider, plus advanced image processing capabilities.  If you wish you can upgrade to MaxIm DL Pro to get complete observatory integration and even more processing and analysis capabilities.\u003c\/p\u003e\n\u003ch2\u003eIncluded Accessories\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/h2\u003e\n\u003cp\u003eEach Aluma camera package includes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaxIm LT software – please use\u003cspan\u003e \u003c\/span\u003ethis form\u003cspan\u003e \u003c\/span\u003eto request your license\u003c\/li\u003e\n\u003cli\u003eDeluxe carrying case\u003c\/li\u003e\n\u003cli\u003eUniversal power supply (110V \/ 220V, 50-60 Hz)\u003c\/li\u003e\n\u003cli\u003e2″ Nosepiece adapter\u003c\/li\u003e\n\u003cli\u003eUSB flash drive containing software, drivers, and documentation\u003c\/li\u003e\n\u003cli\u003e15 foot (4.5 m) USB cable\u003c\/li\u003e\n\u003cli\u003eTracking interface cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eOptional Micron-Precision Filter Wheel\u003c\/h2\u003e\n\u003cp\u003eThe optional FW8S-Aluma 8-position filter wheel includes a positive centering mechanism that precisely centers each filter in the exact same position every time.

those with a permanent installation, but also useful for those who must set up each night to take astro images.  By reporting and charting the seeing from night to night and from hour to hour, the user can determine the optimum time to attempt high resolution images and the times when perhaps equipment better suited to wide field, lower resolution imaging would be advisable.  The Seeing Monitor integrates necessary hardware in a weatherproof box and includes custom software.  The seeing is displayed in units of the zenith Full Width Half Maximum (FWHM) in arcseconds expected for a long exposure star image.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTheory of operation\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMost professional observatories use the Differential Image Motion Monitor (DIMM) technique to measure seeing. This technique is implemented in hardware by using a two hole mask over an 8 to 11 inch Schmidt-Cassegrain telescope aperture, and measuring the root mean square (rms) fluctuation of the spacing of the two spots seen when a bright star is imaged a little bit out of focus with a fast camera. The reason two spots are measured is that the aggregate motion of the two spots due to poor tracking or wind vibration can therefore be rejected. However, the resulting system is complicated to automate, and invariably requires an automated enclosure to house the telescope as well, running the total cost up to many thousands of dollars.  One problem with this approach is that it completely ignores tube currents in the SCT, which are not small, nor correlated across the aperture. The approach used with the SBS Seeing Monitor is to use a fixed single aperture system staring at Polaris, mounted on a heavy solid pier. This way the wind motion and tracking error is gone. Polaris does move across the space of a measurement, so the linear drift of the centroid of Polaris’s position is determined and corrected. We call this the SIMM technique.\u003c\/p\u003e\n\u003cp\u003eAn accurate seeing measurement requires exposures of 0.01 seconds or faster to freeze the seeing, and avoid errors due to the star motion being average over a long exposure. In the case of the SM-4, the software collects 256 frames of date, each with an exposure of 0.01 second.  The rms image motion is then determined. 256 frames requires about a minute of time to collect and process.  A high quality lens (Fig. One, above) with a focal length of 100 mm will achieve sub-pixel accuracy with the centroid calculation, and the motion of Polaris over a night can be contained on the CMOS sensor with a 100 mm focal length.  Over the course of a night Polaris may move in a 180 degree arc, so its motion must be considered for any long term monitoring plan.\u003c\/p\u003e\n\u003cp\u003e \u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/fov_462.png?v=1752163294\"\u003e\u003c\/p\u003e\n\u003cp\u003eFigure Two: Two Summed Exposures of Polaris Field taken with SM-2\u003cbr\u003e(Red Outline Indicates SM-4 Field of View)\u003c\/p\u003e\n\u003cp\u003eAt the latitude of Santa Barbara, CA (35 degrees) the noise floor of an SM-3 with a 100 mm lens is about 0.6 arcseconds FWHM.  This is measured indoors at night by viewing an LED of brightness comparable to Polaris, being driven slowly in a horizontal direction. Understand that this low value will be added in an rms sense to the actual seeing at low levels. So, if a 100 mm lens measures 1.0 arcsecond seeing, one needs to subtract the 0.6 second measured bias from this (in an rms sense) to give the actual seeing, 0.8 arcseconds.  Converting the measured seeing at the elevation of Polaris into a zenith value is done using a well-accepted formula, where the seeing at the zenith is equal to the seeing measured for Polaris divided by the airmass to the 0.6 power. Airmass is equal to 1 divided by the cosine of the quantity 90 degrees minus the latitude.\u003c\/p\u003e\n\u003cp\u003e \u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/setup_menu.jpg?v=1752163306\"\u003e\u003c\/p\u003e\n\u003cp\u003eFigure Three: Setup Menu\u003c\/p\u003e\n\u003cp\u003eSeeing Monitor Menu: here you can choose to immediately start logging the seeing. If you want to start at a specific time select Timed Based and the program will execute for the period commanded. When logging begins, a graph displaying the zenith FWHM (full width half maximum of the star image) will pop up, with a start time which is the previous hour’s number, and that shows 12 hours of data. The length of this graph is fixed at 12 hours.  The graph, and a text file logging the seeing data will be written to the C:\\SeeingMonitor directory every 5 minutes. The seeing graph name never changes, so you can have an external program monitor this folder and put the file up on a web site, if you wish. The logged data file name is the same every time if you start immediate logging, and will overwrite the last night’s file, so change the previous night’s text file name manually if you wish to save it. When operating in a multi-night mode using a timed start and finish the file name is customized with the date, so the previous night’s data will not be overwritten. The seeing graph is always overwritten.\u003c\/p\u003e\n\u003cp\u003e \u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/display1.jpg?v=1752163319\"\u003e\u003c\/p\u003e\n\u003cp\u003eFigure Four: Main Screen\u003c\/p\u003e\n\u003cp\u003e \u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/seeinggraph_05215.png?v=1752163473\"\u003e\u003c\/p\u003e\n\u003cp\u003eFigure Five: Seeing Graph\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003eOn the graph shown in figure five, above, the white data points record the seeing number in arc seconds.  The blue data points represent the brightness of polaris at the time of each measurement.  You can see from the graph that on this night the seeing began to deteriorate around 3:00AM and got rapidly worse over the next 45 minutes until it was useless to image.  The brightness of Polaris also began to deteriorate at the same time, which together indicates encroaching clouds or fog.  Even when sampling at 100 times a second, when the seeing is REALLY bad the seeing monitor is probably underestimating how bad it is since the image is just a boiling blob. Even though the seeing monitor underestimates these terrible nights, it provides a clear indication that you would be better off doing something other than astro-imaging that night.  The usefulness of the seeing monitor is readily displayed in the next Figure, below.  This is an animation of 13 graphs taken over a two week period.  As you can see, the seeing, and the patterns of good vs. poor seeing per night, vary a great deal making it almost impossible to rely on history or experience to predict when the night will be worthy of hour long exposure efforts, or not.\u003c\/p\u003e\n\u003cp\u003e \u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/anigif1-1.gif?v=1752163485\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/untitled-2.png?v=1752163497\"\u003e\u003c\/p\u003e\n\u003cdiv class=\"clear\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"content product_content\"\u003e\n\u003ch3\u003eModel SM-4 EX\u003c\/h3\u003e\n\u003cp\u003e \u003cspan\u003eThe model SM-4EX adds a USB 3 extender over Cat 6 or 7 or 8 cable to a standard SM-4 for operation up to several hundred feet from the control computer*.  An auxillary power supply is used at the computer providing ample power over the Ethernet cable to power the remote receiver and the camera.  Remote operation is therefore achieved using only a user supplied ethernet cable.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe SM-4 EX includes a standard SM-4 plus a USB 3 to Ethernet transmitter unit, an Ethernet to USB 3 receiver unit installed in the housing with the camera, AC power supply and USB cables.  User supplies the length of Cat 6 or 7 or 8 cable necessary to meet their needs*\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/sm-4ex-1.630x0.png?v=1752163509\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/img_0480-2.599x0.jpg?v=1752163520\"\u003e   \u003c\/p\u003e\n\u003cp\u003e   * NOTE:  We have tested the SM-4 EX using the following lengths of CAT cables:\u003c\/p\u003e\n\u003cp\u003e   150' of buriable CAT 6 with no apparent problem\u003cbr\u003e   200' of buriable CAT 7 with intermittent connection issues - this may be just at the limit for CAT 7\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cp\u003eSanta Barbara Scientific Seeing Monitor (SM-4)\u003c\/p\u003e\n\u003cp\u003eUSB3 to ethernet adaptor (inside) (SM-4 EX ONLY)\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eWarranty \u0026amp; Manuals\u003c\/h3\u003e\n\u003cp\u003eSanta Barbara Scientific Warranty\u003c\/p\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" href=\"https:\/\/www.sbscientific.com\/site\/assets\/files\/56059\/sm-4_seeing_monitor_instructions_v4.pdf\" target=\"_blank\"\u003eManual\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Santa Barbara Scientific","offers":[{"title":"SM-4","offer_id":47191720952037,"sku":"SBS-SM-4","price":2589.0,"currency_code":"CAD","in_stock":true},{"title":"SM-4 EX (with usb3 to ethernet)","offer_id":47191720984805,"sku":"SBS-SM-4-EX","price":3429.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/1_2f4f9692-6a57-4ba5-9d2d-179d15b93515.webp?v=1752165414"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/collections\/sbig-astronomy-plus_d807209b-1ff9-4709-94e9-c8e39c1dd7d1.png?v=1715807956","url":"https:\/\/istronomyplus.com\/collections\/sbig.oembed","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
