    What did the postman bring?

    What scope will you try it with Stu?

    A quick session with the 72ED

    Thanks, I've done a few reports over recent years with this scope (probably looking at the same objects!) so i'll see if I can link to them for your interest. It is a versatile scope, useful for grab and go, solar, widefeld imaging and as a finder, although my 66mm is better for the latter as it is quite a bit lighter. That's quite some guidescope! Definitely deserves some eyeball time to appreciate those lovely pinpoint stars. Clusters and doubles will look fantastic I think. Thanks. Yes most of the reports of successful observations were with large intruments, some claimed to have seen it with small instruments, but I think 72mm without an filter is beyond hopeful! You must have had a wonderful night with the 14" dob at a dark sky location.

    ASI294 Pro – M81/82 first light

    What stands out for me is what you can capture with a single 25 second sub - very impressive. The F4 Quattro is clearly a nice match for the camera. looking forward to seeing some more.
  4. Went out at 11pm on Sunday to test my new 'light shield' setup, and discovered a wonderfully clear sky so decided to make the most of it with a quick grab and go session. I carried out the 72mm frac on the Giro-WR and was observing within a couple of minutes. Not having prepared a target list, I just had a random scan of interesting objects to get my 'fix'. Denebola – lovely split, best at around x80 but just visible with at x50. M67 Cancer - a beautiful compact and well defined cluster, seemingly many unresolved stars, taking up a 1/3 of FOV at x43 Eskimo Nebula (NGC2392) - lying close to a similar magnitude star and unmistakable as non-stellar, with a bright core and fainter but well defined outer region. Medusa Nebula (Abel 21) - Feeling (over) confident I thought I would have a go at the nearby medusa nebula. Having observed this with my EAA setup I knew this was challenging, but even with the UHC filter I could not see it. Subsequent research was inconclusive about the size of scope required, but it seems like an OIII filter is a must and upwards of 80cms aperture. Onto some galaxies, M65 and 66 easily see, M66 having a faint star very close by. I tried for nearby NGC3628 but couldn't claim to see it. M96 was nicely visible and M105 nearby, but its companions not so easy, just hints. M51 was nicely visible, with two cores apparent. M101 was surprisingly easily, it often seems quite a challenge but tonight's conditions must have been good. Pleased to be making use of the capable little frac, but I must have a target list prepared for next time.

    Most satisfying observations?

    I would imagine that anything in an ST80 would be awesome from the mountains of Nepal !

    LX850 First Light.....at last!

    That's a fantastic looking setup and the Starlock sounds superb, really pleased it works well. A FL of 1500cms @ F5 should open up an interesting world of imaging opportunities.
  7. From the video, it looks like the dewshield reverses and becomes a slide on protector, very clever!
  8. What a lovely looking piece of kit, perfect for a lightweight mount, clever design fusion of APO scope and SLR lens.

    Widefield scanning of nebulae

    Amazing stuff, some lovely captures there.
  10. I sympathise, my distance vision has deteriorated over the last couple of years (I am 53) when I look at the night sky the stars are blurred but apparently my vision (in my right eye at least) is 20-20 according to the optician and I don’t need distance glasses yet. I think as an astronomer I am much more conscious of sharpness of vision, the optician didn’t buy that though! Regarding your problem, the only time I have experienced the kind of discomfort you are describing is when looking through poorly collimated binoculars and trying to correct the double vision. Obviously not relevant to your situation though. Sounds like there is some effect occurring, you just need the right optician to find out.

    What was your first scope?

    My first was in 1979; a fullerscopes 6” F8 Newtonian on a Charles Frank manual EQ mount. My dad and I built a roll on roll off obsy and a I had many years of fun with that setup before it had to be sold to fund further education. A classic setup, very fond memories.

    Bright sights, cold night.

    You always get so much pleasure from your sessions Nick, and I always enjoy reading.
  13. A nice little session Doug, sounds like the scope is performing well. I'm surpised the ED80 is not used more widely used for visual, its got a focal length which is not so short that it is just rich field, and not too long to stop it being very portable. Hope you get to use it a lot more. Edit: Just realised yours is the Explore Scientific triplet, not the Sw doublet which I had assumed. I am guessing it is still pretty portable though.

    Hong Kong Light Pollution

    Well done for managing any observing in those conditions! Respect to all the ‘inner city’ astronomers out there. Makes me feel lucky that my major obstacle is next door’s bathroom light (and clouds!).

    A Minimalist Setup

    That is a nice minimalist setup, should yield some good things, fingers crossed. The mount seems huge compared to the scope, I thought it was an NEQ6 at first!
