    Worthy stars.

    I put together this short list of most interesting stars. You might have read or heard of their names . Be it their age , size or appearance , they provide some entertainment , even under light polluted , but clear skies ! Nick.

    Cloudy Skies every night

    Don't take any notice of weather forecasting . They couldn't find their backsides with both hands ! I've had 4 sessions this year by going out and looking . Last night , despite the forecast of doom,I had a clear couple of hours. For some time I just stood and looked at Gemini and Auriga . Thinking " I know what's up there and where they are !" Our weather might have changed to become more variable and drastic , but forecasting just can't keep up. old Nick.

    Taurus delights.

    Neq6 pro, holds the C6r really steady . We have been really lucky with gaps in the weather . We often get stuck in a middle England trough ! Old Nick.
  5. Just a couple of hours to enjoy riding Taurus from a comfy seat . Quite surprising seeing , getting down to 1.2". Σ7 and Σ401 appear closed towards each other . SAO 75970 H 1V 98, a bright pair of eyes , facing another pair. SAO 111698 Σ559, a nice close even pair . SAO 94002 Σ749 , close at 1.2". At 05h37.1m. +26 55' β87 , close with a faint companion,1.9". SAO 76571 Σ517, close with a lovely delicate companion. SAO 111705 88 Tauri, a wide view , yellow and red. At 04h35.7m. +10 10' Σ479, a fine triple with differing magnitudes , lovely view at 04h00.9m. +23 12'. Some lovely views , under , Clear skies ! Nick.

    Full sky haul !

    Beautiful dark and clear sky , the wind dropped and we got to just below freezing. Sky packed full. Orion glided westwards leaving a clear open Monoceros. First shock was a superb view of NGC 2261, "Hubble's variable Nebula" must have been at the peak of brightness , lovely view. Not seen this one before , worth catching. Caught a lovely bright disc of Uranus in the south west. Trawled through the open clusters of Monoceros . The best I have highlighted, NGC 2232 gave a very bright large "fish " shape , really lovely. Had a look at "Hinds crimson " star in Lepus , but not so bright just now. Then some overlooked Messier's, M41, M67, M48, and M46. Leo was quite high and a lovely view of the bright streak of NCC 2903. Ursa Major gave a very surprising bright view of the galaxy NGC 2841, between Talitha and theta. Sight of the night was a very tight binary , Struve 1338 (SAO 61411) in Lynx. This has closed to 1.0" . It took several changes of eyepieces and moving the star around the fov , before I got a clean split with a hair width between them . That was at x240 using a Vixen LVW. That's some decent seeing ! That's a distance of 43AU up there. Light cloud started up , a really lovely session , under clear skies ! Nick.

    Synscan , so what are your results ?

    The AVX doesn't seem to have the odd variations. I was not tempted , extension pillars aren't off the shelf, the payload is a bit lower than the 5pro, it's noisy ( less so than his previous Coffee Grinder 5)and you can get just about everything you need for SW mounts pretty easily. I also found Nexstar a right pain ! Very surprised to see that other users are getting variation , Nick.
  8. Having used Eq5pro (belt drive) and Eq6 mounts for some time, it has been a source of puzzlement why every time I get different accuracy results. The following have been the same ; power supply , regulated bench supply. levelling and balancing , rigorous. All bolts snipped up before use. Some of those extension pillar bolts have a dance of their own. position, tripod leg bases positioned into drilled out holes in paving. Home position marked on the mount . Time , date , long /lat , time zone , BST all ok. Polar alignment (not a factor in alignment , but useful for settling a view), as close as possible. Synscan versions , 03.39.03 and 04.39.04 alignment stars , either one star if studying one area of the sky. Two stars , low , east and west . Three stars , zenith , then east and west. Aligning, ending in "up" and "right" using a 12mm illuminated reticle. scopes , set accurately on the dovetail . ok , some nights , first star, nearly there . Other nights , about six degrees out . Second star , some nights it's very close to the reticle. Other nights , it might be a degree out. Ok. Alignment done, now goto. some nights , targets are to one side of a x50 fov. Once corrected by the handset , performance is great. Some nights from the start , it'll bang targets centred at x200. Now , in no way am I complaining or moaning . It's just puzzling . I spend a lot of time on binary stars and these are pretty obvious in the fov, so a bit of leeway is ok. Every time I switch on , I don't know what to expect . It certainly comes to a head when my friend with his AVX called Synscan rubbish ! Luckily at outreach or star parties everything behaves ! The only thing that I can think of is ambient temperature acting on poor tolerances of man versus machine ! Any other Synscan dice throwers out there ? old Nick.

    A bit of research !

    Blithely observing and listing sky objects can be greatly enhanced by a small amount of reading up. I was always intrigued by the central star of the Eskimo Nebula. A short excursion provided the background to white dwarf stars and the evolution of stars in general. It is still miraculous to me that we can not only observe features such as NGC 2419, but find out about its age , distance and theories of both globular clusters and galaxies. It's also a great addition to outreach events ,especially when most folk have not looked through or a telescope or the whole night sky. I'm no scientist and pretty forgetful clumsy chap , but certain things stick better when you've seen them and taken a bit of effort to find out more. I was explaining the 11 year solar cycle , suddenly remembering the rebooting and subsequent contortions of the solar magnetic field. Hopefully such things will encourage others to look deeper into what we see, under clear skies ! Nick.

    Super Bogardus.

    Dunno, wrote it in my book and used it ever since .Probably from my main source of misinformation , Wikipedia . Can't remember Mahasim , too many stars beginning with M , Nick.

    Second session this year !

     Great report, Nick. What magnification did you use to get the triple? X218 gave the cleanest view . Under favourable seeing it can open up at lower magnification,a stirring sight !

    Second session this year !

    Early start with clear sky , caught the comet in Lynx. Then clouds rolled in , managed to wake up and at 2 , it looked beautifully dark and clear . Gave it a couple of frosty hours before cloud rolled in again. Enough time to visit the spectacular , M37 in Auriga , try this at x100 to fill the view. The very similar M67 also looked great. Another visit to the comet 46P in Lynx. Whilst there , just a tiny sparkle of the globular cluster ,NGC 2419 , our most distant Milky Way target , way out of the halo. "La Superba" YCnV, a cheery bright orange star. (SAO 44317) Iota Cancri , a "winter Albireo" giving lots of colour .( 08h46.7m +28 46') Tegmine , just about opened up this triple in Cancer (Zeta 1 and 2), beautiful triple.(SAO 97645) M94 , bright glow , but not much of a morning as cloud was filtering in here and Leo. 14 Aurigae , tried again for the third element . This is a quintriple group, mainly visual companions with spectroscopic companions . The main star is an interesting cool white star , arriving at the point when Hydrogen fusion is ending. It was an easy catch in an 8" Newt , also catching a fourth element.(SAO 57799) Hoping for a great year with clear skies ! Nick.

    A break in the clouds

    DO refers to the Dolidze catalogue of open clusters. Many have been incorporated into the NGC catalogue, https://www.stellar-journeys.org/cluster-dolidze-info.htm Nick.
  14. Pretty shabby evening , with damp murk arriving . Just a spin around Auriga and the best view of θ Aurigae (Bogardus) SAO 58636, yet. The tiny companion was evident at low power. Giving it x200 gave a remarkably clear view. This companion is +7.2 compared to the A at +2.65 at a distance of 4". This corresponds to a distance of 185 Au apart for the pair. There is a visual third star here at 52". Good enjoyable view for clear skies ! Nick.

    Where are the Canali?

    That's really beautiful . It's great to see drawings of great detail and passion for the observed . Personally , I thought the caneli were left over river systems from when Mars had seas up to a mile deep. old Nick.
