  1. Bear in mind the telescope was picked up very cheap as a customer return... A Sky-Watcher 9x50 RACI finder scope I already had, with a black bracket sourced from an SGL member. Bob's Knobs cost too much. 35mm knurled thumbscrews replaced the collimation grub screws. Collimation is now tool free and less fiddly. https://www.wdscomponents.com/en-gb/adjusting-screw-steel-metric-wds-605/c-385/p-495/v-5926 A TS-Optics 1.25" Crayford focuser. 4x m4 counter sunk screws bought separately. I used 16mm length but 10mm would probably do. https://www.teleskop-express.de/shop/product_info.php/language/en/info/p7836_TS-Optics-1-25--Newton-Crayford-Okularauszug-aus-Metall-mit-T2-Anschluss.html It's not a straight swap. A Dremmel, hand tapping tool & dust free towel were needed. The draw tube hole required widening, with four screw holes drilled and tapped. The towel was stuffed down the tube to protect the primary. The white dots below are just for illustration. They're not in the exact positions A Sky-Watcher 21cm dovetail bar attached to Orion 182mm tube rings. (Sky-Watcher are cheaper but they're white) https://www.harrisontelescopes.co.uk/acatalog/skywatcher-medium-dovetail-bar.html https://www.amazon.co.uk/dp/B0000XMXZW?tag=duc08-21&linkCode=osi&th=1&psc=1 The screw holes left behind after removing the small integral dovetail were filled with plastic covers. They were slightly too small for the holes so were secured with a couple spots of UHU glue. https://www.ebay.co.uk/itm/8mm-x-4mm-Hole-Plugs-Plastic-Blanking-Masking-Finishing-Inserts-Black/221912851461?hash=item33ab096405:g:WYYAAOSwNkJaKBJC The weight with the 9x50 & Celestron XCel LX 25mm eyepiece is 5.2kg. With a standard plastic red dot finder and a 25mm Celestron XCel LX eyepiece, 4.75kg.
  2. I've owned a 130PS and currently possess (a somewhat customised) 150i. The 130PS was used for many months. Primary collimation was fine on delivery and remained so. Secondary collimation was infrequent. Collimation of the secondary is a simple process taking a minute or so at most with either a collimation cap or cheshire. The 150i tube I picked up cheap relatively recently and made some improvements, while keeping it significantly lighter than a standard 150p. The mirrors are the same quality as their "vanilla" Sky-Watcher counterparts. The 150i after a tinker :
  3. An interesting talk. Jeremy, I'm aware of variables, especially cepheids and their role in astronomical distance measurement, but was totally unaware of the cataclysmic class! The talk prompted some futher reading, so you taught at least one person something new tonight. Also, Gary Poyner's explanation of magnitude visual measurement hit the spot. Thanks very much!
  4. Watching now. Jeremy's dead posh like, you know warrah mean?!
  5. For "lunar, planetary and the odd cluster", a 102mm Mak would do the job. Smaller, lighter and much cheaper than a 127 if you just want a little grab and go set up. A tack sharp view up to 200x. Short cool down time (15 mins?). No complaints. I love mine, it compliments the 6" newtonian really well and doesn't tax the AZ-GTI at all.
  6. Indeed there is (ta. ) There's room for one or two more, maybe a 5mm. The old case has been repurposed to hold 2x rdf, some tools and a laser collimator.
  7. Got mine today. I don't think it will take too many hard knocks but, at £17.99 inc. post one cannot complain!
  8. Very nice. My kids think I'm a geek, so bought me a similar Nasa/Space Shuttle T-shirt for Fathers' Day...
  9. Paul, as it's a loose group of people attending and booking via the camp site, rather than a formal gathering of a club, then I'm fairly sure you're not liable for any accident taking place on the premises were the incident involves site equipment eg a step or cattle grid. If on the other hand, someone trips over a guy rope, breaking a leg or bangs their head on your heavy mount, causing a fractured skull and decides to sue, then that could be tricky!
  10. Don't panic! Bruce Willis will sort it...
  11. Ryzen 5 knocks blocks off the i5 if you're multitasking or the software used supports all their cores during multicore processing. They also overclock quite well if you're confident. Plus they're cheaper! I mentioned elsewhere I have two, three year old, overclocked & liquid cooled Ryzen 5 1600s at home. Brilliant for what they cost.
  12. Thanks. My aim was to keep things small and portable, while maintaining some variation. Plus not spending too much! Something brand new entrants need to bear in mind. The telescope is just the tip of the spear. The accessories can cost more than the scope & take up more space! All the bags work as intended, although the TS-Optics focuser fitted to the 150p only just fits into the bag. The focus wheels are quite spaced out.
  13. The whole lot. In *theory* it can be carried from car to observing area in one go... The Oplok bag for small telescopes fits two tripods (1x 1.75" steel and 1x aluminium Star Adventurer), an AZGTI, AZ5, finders and assorted stuff. The 150p in its own bag. A camera bag for the Skymax 102, diagonal and rdf. Plus a waterproof case with six eyepieces.
  14. As an example, I live in Bortle 8. 5.5 miles outside of a large city centre but, still within the city boundary. Multiple sources of local light pollution, i.e. street lights, neighbours' windows and security lighting. Plus surrounding sky glow from one million people squashed together. If i had an astronomer friend or relative living in Bortle 5, I'd be happy observing in their yard, but I wouldn't travel a significant distance just to observe at Bortle 5, or usually book a holiday with observing time in any more than Bortle 4 (rural/semi rural) Bortle 5 is moderate light pollution, usually encountered in a less densely populated suburban area on the fringes of a town or urban conurbation.
