    So I had some unfinished business with Izar. Tonight I tried again using the same scope (6" f/6 Newt) with Izar at about the same altitude as last time out, and I am now very sure I was looking at the right star (it's not hard to find, after all...) and I had similar difficulty splitting it. The differing colours made both stars visible, but no space between. I decided that perhaps the low altitude combined with the fact that I was gazing out over the entire town was making it difficult. So I tried again later on when Bootes was much higher, and this time I could indeed split Izar. Still very close, but clearly separated. The lowest power at which I could see the split was 180x. Perhaps my new focuser helped a bit as well.

    Fancy a week with professional astronomers? This looks amazing! http://mao.tfai.vu.lt/schools/index.php?option=com_content&task=view&id=138&Itemid=232 Europlanet Summer School 2018 Eurplanet 2020 (RI) and the Molėtai Astronomical Observatory (ITPA VU) are pleased to announce the international research summer school „Space missions: ground-based observations and science communication“. The aim of the course is to give participants a thorough, multidisciplinary introduction into space missions and the ground-based observations required by space missions before and after launch, as well as an introduction to science communication. More general subjects about specific space missions (TESS, JWST, PLATO…), planetary systems, habitability of planets, photometric and spectroscopic techniques will be presented. Participants will be given some hands-on experience with analysis of stellar chemical composition, detection of stellar variability and/or exoplanets using the Molėtai Astronomical Observatory telescopes (CCD photometry and high-resolution spectroscopy). In addition, the course will give participants the opportunity to develop comprehensive theoretical and practical skills in science communication and engaging with a range of lay audiences, including the public, media, policy makers, schools and educators. The course is open to PhD and master students, early career scientists, and amateur astronomers. Activities of professional astronomers and amateur astronomers will be merged in order to achieve more understanding between groups. The level of the school is orientated to PhD students and early career scientists, however amateur astronomers will be provided with the additional scientific support during lectures and observations. For selected* participants from the European Economic Area (EEA) the participation will be fully covered and up to EUR 360,- for travel depending on the distance travelled will be reimbursed by EUROPLANET 2020. Other selected participants will have to pay a participation fee of 600 EUR that includes accomodation, meals, excursions and local transportation. The school is organised by the European Commission HORIZON 2020 project EUROPLANET 2020 Research Infrastructure. The deadline for application is 31 May 2018 23:59:00 UTC. Notifications of acceptance by 15 June 2018 23:59:00 UTC Helen

    It is a stunning pair, isn't it. With a 2.8 arcsec separation , minimum theoretical mag to see the split would be abou x60 (160/sep). As you say, maybe your rising warm air over the town wasn't helping. It is a pair I show to visitors with my grab'n go mak (127) to demonstrate how colourful doubles can really appear, compared with those grey, faint fuzzy thingies! Chris

    Yet another potential eBay scam with a starting price of £99 but in the description claims a buy it now only price of £1000 and all bids will be canceled. https://m.ebay.co.uk/itm/Like-New-Open-Box-Takahashi-FS-102-Flourite-Apochromat-Telescope-Only/332587213555?hash=item4d6fbe22f3:g:cCgAAOSwfghaqslC

    Great result with the cable, cheaper than buying a new Lifepo4 battery. It seems to me that the NEQ6 needs a bit more voltage than a lot of other items, I wonder if Tracer could adjust the output up a bit on the Lipo type to suit the mount, something like Neil (Stub) suggested (boosterthing) above and I am sure Tracer would have built in low voltage protection - all our radio control gear soon did and that was years ago.

    Great report Mike, long and nice list of doubles there! I really should spent more on them too.

    The pattern looks a bit like very low resolution spectra which would imply there is something that is acting as a bit of a diffraction grating. I wonder whether it is the underside of the mirror on the camera and it has a slightly rough surface? That would align to the idea that there is something horizontal in the light path.

    Yes, everything is better in the new version, including colour, contrast and stars. It really make the Herbig-Haro 555 object stand out. If you have a lot of old data to process with the new workflow you may not need clear skies for a while.

    great shots under the conditions Pete, ive never had a image any bigger than a point of light with Mercury. well done. charl.
