  1. My club's Atlas is stuck on the date 11/13/2099. Last night was 6/28/2019. Every time I reset the date and started the 3 star alignment the scope chose Vega and then pointed to the western sky - sorta wonky. When I tried a second star it aimed at a totally wrong part of the sky. I went back to date and it had reset to the11/13/2099 date. The mount has a working GPS module. I went through all the menus and there was no place other than the " sub menu to attempt to replace the errant date. After five tries I gave up. Apparently the GPS was accurate to withing a stride or two. What should I try next? I know my club; they'd rather stuff it in a corner than take the time or money to fix it. So it will be m time and my money. I used the mount several times this year and had no problem.
  2. Stars to 9.75 magnitude & 30000 non-stellar objects. Not a beginner's atlas (try Phillips, less detail) but an inspiration to amateurs. Back when U2K was first released, I snapped up the Northern Hemisphere vol. (Southern had its own). I was & still am a fan of Wil Tirion's draughtsmanship from Collins Field Guide to Phillips to Atlas of the Night Sky to Uranometria. When 2000 AD was still a future date. This All Sky Edition has both hemispheres in 1 book. While Night Sky (which also has a white objects on black background version) has large fold out pages or large separate sheets for field use, Uranometria is more library/reference use. But U2K is wonderful in its magnified detail and indexes for help in finding charts, of which there are 220. In addition there are 26 charts of more detailed areas showing star magnitudes down to 11.5 and DSOs with smaller separations etc. On the main charts, stellar magnitude goes to 9.7 from 0.0 and brighter. Double/multiple stars are shown as individual down to 60" separation. Variable stars down to 4 amplitude. Novas, quasars, radio souces & X-ray sources are shown. Galaxies, clusters, & nebulae are to scale. The atlas has a separate index for; Bayer stars in each constellation, named stars alphabetically, Messier objects with type, common names, and NGC/IC objects. At the front is a chart of each pole & the celestial polar areas showing the main chart number to go to, then a page listing them as well. Want the Veil Nebula? Not sure where it is? Go to Common Names index which says it's on charts 47, and there it is filling a credit card sized area of a page. Pleiades on chart 78 not detailed enough? Chart A12 expands the area of 27 down to 21 degrees, and 3h 58m across to 3h 38m over a whole page. Copyright violation paranoia stops me from uploading photos, but this book, for less than the price of some planetarium software DVDs, is a great bargain to me. I bought mine from FLO, cheaper than Amazon. It is not for stellar observation beginners, but could be for DSO hunters due to the larger scale for nebula & clusters etc. Galaxies depend on size, but looking at chart A13 detailing the Virgo galaxy cluster, the shapes of larger ones such as (elliptical super giant) M87 give an indication of what you might, or might not see.
  3. I seem to have keen eyes for certain things at car boot sales... last week I missed a very nice Canon digital camera for £20 (my dad bought it instead, I was jealous of his find), this week I picked up another Stellarscope type instrument, but it is much smaller, lighter, self-contained, and has a built-in red LED light. When I looked this up I see that it costs £20 - £30! I got mine for 30p. Also has a little compass in the end. The batteries had leaked a bit, as is usually the case with such things, but a quick wipe off of the residue powder and they are good as new. I'll be testing it out tonight if the skies are clear.
  4. I decided a couple months ago that i am going to upgrade to an EQ mount. I am currently imaging with an Astrotrac but as much as i like it, i have outgrown it and am wanting to move onto building up a proper imaging rig. My plan is to buy a mount within the next couple of months and use my DSLR and 200mm lens for imaging until next year when i will be adding a scope to it, or i may even buy an autoguider before that. I want the mount to be reasonable, meaning i want it to be decent with enough features and payload capacity that i won't have to upgrade it for at least a couple of years. I have narrowed it down to 3 mounts: The Orion Atlas EQ-G, Skywatcher EQ6 and the Celestron CGEM GOTO. I understand that the Orion and SW are the same mount. Both are just under £1000 which is my budget. The CGEM is about £300 more, but i am willing to stretch to that is it is worth it. So what would you get if you had to make the decision? Are there any major differences between the EQ-G and EQ6 other that looks, and what does the CGEM have thats worth the extra £300 on the price tag (other than good looks). Would be great to hear from someone who has had experience with any of these mounts. Also, if anyone has another mount they would recommend then i'm all ears! Cheers
