    What did the postman bring?

    Phew, thank goodness, I thought you'd got it to polish your Taks

    ST80 does what it does best

    I only ever see it as ET. I'd much rather see an owl. This, along with the Pleiades and the coat hanger(cr399) were probably my favourites in my ST80. Good session - did you sketch any of the others?
  3. Yes for visual, if it has a reasonable tripod and NOT the one shown. Check the axes rotate smoothly, unless you're happy to strip it down and re-grease.
  4. @msacco, I had it's predecessor, Helios 8", on an EQ5. The mount was an old one with a box-section tripod. It was not up to the job. I replaced the tripod with Vixen HAL 110 and the mount was absolutely fine for visual (not tried it for APP). The later EQ5s come with a better round-section tripod which should be OK. Older EQ5, like mine, used bad grease on the RA and DEC axes which sets like glue and made the axes very stiff. After I stripped it down and used a lithium based grease (sorry, I can't remember which one now), it worked fine.
  5. In addition to the optical quailty (using a wide range of standard and quality eps) I'd like to know if a GPD2 mount would be up to the job for visual and how easy it is for one person to get on and off the mount.
  6. And/Or you could join the British Astronomical Association Variable Star Section. The BAA and AAVSO databases are linked and there is very strong links between the two organisations. I think the BAA VSS is the oldest variable star organisation, started in 1890. There is much information for the beginner on the web site.
  7. I'm more concerned on what the LED colour temperature of the lights fitted outside my house is. A presentation was made the recent BAA/AAVSO meeting at Warwick by a member of the American Medical Association reporting significant increase in risk from cancer when exposed to LED light of higher colour temperature than 3000K. One BAA member's local council has installed 5700K lights (which are as toxic as it gets) everywhere apart from their National Parks, where they have installed 4000K ones (which are still bad enough). Anyone doubting the validity of the recent research should know that the 2017 Nobel prize for Physiology or Medicine was awarded for some work on it. You want your lights to be <3000K (or tuned off after midnight). See https://www.telegraph.co.uk/science/2018/04/26/new-led-streetlights-may-double-cancer-risk-new-research-warns/ for a summary. I'm requested the specification from my local council, with a view to ensuring that the lights outside my house are 2700K ones. I've fitted blackout curtains but a significant amount of light still leaks in round the sides I see yours are going to be 4000K ones, I believe the latest research shows that these still pose significant health risk.
  8. Excellent post RayD, thanks for the full explanation. I don't agree with this quoted bit. [RANT] I had a Helios 8"F5 newt from Synta (who own both Celestron and SW) with a focuser that flopped from side to side on an EQ5 that used grease that turned into something like Evostick after a couple of years, on a box section tripod that couldn't really support the mount - without the telescope on it. And as for my AZ3 .... [/ENDRANT] Of course I blame the bean counters and not the engineers for these. My C8 and SW Mak127 are brilliant. I guess things have moved on since then.
  9. I prefer, and subscribe to , Sky and Telescope, even with the American spelling and grammar. That and the BAA journal and Webb Soc. DSO keep me happy. If one had to go, it would be S&T.

    Organising your imaging files

    I'm not an imager, so use a notebook. "Observatory" from Codeobsession for the Mac got a very favourable review in Sky and Telescope recently. https://codeobsession.com/observatory/

    rho ophiuchi

    I can see more detail in the second one, but prefer the colour of the first one. It seems more "natural".
  12. You can get latest happenings in the outer planets from BAA web site or from http://pvol2.ehu.eus/pvol2/ e.g. Jupiter alert: Convective outbreak in Jupiter's South Temperate Belt 2018. To get the latest images available use the 'search data' option.

    Dark skies here I come.

    Good luck with the weather! Let us know how you get on.
  14. I had a ST80 and loved it. I had fantastic views of Mars with it in Portugal years ago. Polar caps, clouds, Syrtis standing out like Africa. I sold it and bought a TS80APO, which is a good APO scope, no false colour, astrophotography capable blah blah blah, but twice as heavy. Wish I hadn't. Hardly ever do astrophotography, not worth the difference.
