Many thanks to all the contributors, to Zena and Annabelle and to all who helped with the ‘housekeeping’ chores. Ken also illustrated and described the equipment he uses including several of the DIY electronic elements he constructed for controlling the scope and imaging. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. Ken Honour shared his superb images of the Whirlpool, Needle and Blackeye galaxies as well as NBL_618, Cave, NGC7380, NGC7000 and the Heart nebulae. The prototype achieved first light in 2017 June, followed by its official inauguration in 2017. Stellarium is a free open source planetarium for your computer. Given that the transit time was 0.5 seconds this was quite a feat! She’d captured this with a 600mm lens on her Canon DSLR. Brzsnyi, S., Kossmann, D., Stocker, K.: The skyline operator. Jan Wrightson treated us to a great image of the ISS transiting the sun. We were encouraged to observe that colourful double star Albiero (Beta Cygni) at the head of the swan and which is well placed for viewing now. Clean only when absolutely necessary and then with great care.ĭuring the break Caroline Clements impressed many interested members by showing how easy it was to set up and use her Celestron NexStar ‘scope.Īrthur Davis presented Cygnus as the Constellation of the month featuring NGC7000 the North America nebula and IC5070 Pelican Nebula. One thread that emerged was that ‘if it ‘aint broke don’t fix it’ especially when it comes to a bit of dust on mirrors and lenses. Bud led the question and answer session, covering topics like the cleaning of lenses and eyepieces, collimation and polar aligning. We publish stories you sent us about important moments that you made into a star map. Please check the links below.As Mike Witt our scheduled speaker couldn’t make it, we decided to use the time to talk about the care and use of equipment. And diary of astronomical events for a month. We have also given some information stars and constellation associated with each month. Click on the map to Enlarge, save and print. You may, of course print these on a black and white printer. You can get back the text using white or green light. You may print these maps on a colour printer and when use with red touch light the text will nearly disappear and only the stars will be seen. The first set of maps are coloured maps and maps in Duo colour where the text is given red in colour. These stars form what are called asterism which is a group of stars not part of standard list of 88 constellations recognized by the International Astronomical Union but popularized by amateur astronomers. At times some stars are joined with broken lines. Most constellations are shown by joining straight lines. That is brighter stars are marked with bigger dots. The stars are shown with dots in proportion to their brightness or magnitudes. In this projection system the objects closer to the periphery, in this case the constellations closer to horizon would look slightly bigger than those close to the zenith. The maps are drawn using stereographic projection ( see wiki link), that preserves the shape but distorts the size. That is the angular diameter of the horizon circle is 220 deg. ![]() The maps shows slightly more sky than that will be visible from this station. +23deg 11′), at 21:00 hours Indian Standard Time (IST). The star map given here are drawn for central station of India (Long 82.5, Lat. They occur every year between July 17 and August 24 and tend to peak around August 9.

Given below are two sets of all sky star maps. No member of this committee subscribes to astrology.) We would also talk about positions of planets (grahas) in different constellation which is for the purpose of where to look for those. We have tried to give the Indian names of the stars and constellations (like Nakshtras) for the purpose to remind the reader of this rich tradition. (Disclaimer: India has a great astronomical tradition. ![]()
