  1. Past hour
  2. Almost certainly a power issue I would say.
  3. Vicki - thats looks so 3d I could almost lift it off the screen. The colour and detail is great, well worth the effort. The panels are seemlessly joined. It looks like it could even take a little bit more sharpening too. Fab.
  4. Nice - that's a substantial looking mount too - which model is it ? Do you find being on the flagstones/patio ok?
  5. Some months back I asked on here how to create a colour moon. Well, months later and I'm finally getting it This was processed in Photoshop and its a 6 panel mosaic captured in SharpCap Pro with an Altair GpCam2 290c and Skywatcher 130P AZ GOTO
  6. Hi John, I run mine from one of these. Seems to last ages. https://www.amazon.co.uk/TalentCell-Rechargeable-6000mAh-12000mAh-Lithium/dp/B0713T4XT9/ref=sr_1_2?crid=2MCDBVU1T0XFW&keywords=talentcell+rechargeable+12v&qid=1556206673&s=gateway&sprefix=talentcell+%2Caps%2C150&sr=8-2 Alternatively it should run from any centre positive 12v supply with a 5.5 / 2.1mm plug. I doubt you'd need one that puts out any more than an amp. I've not tried this, but this one would probably do the job. https://www.amazon.co.uk/LightingWill-Supply-Adapter-100-240V-Transformer/dp/B07P71DTSP/ref=sr_1_3?crid=1AYU0YYNBI6C4&keywords=12v+1a+power+supply&qid=1556206777&s=gateway&sprefix=12v+1a+%2Caps%2C165&sr=8-3 Cheers Jim
  7. I've been in Ireland for nearly a week now, and last night my skies finally cleared. I had my 12" newt and APM-LZOS 105/650 mounted together on the AZ EQ6. After my frustrations last time when I discovered SW's dual-saddle doesn't point where the main saddle points and doesn't have "sideways" shiftability, I got myself a Baader Stronghold adjuster which has 2 degrees of freedom: effectively another alt-az but mounted sideways. The night sky was something to behold. Once astro dark had set in, 2 minutes outside was enough to see the Beehive Cluster naked eye. And once again, picking out Ursa Minor from the surrounding stars was an effort, it was all so bright. It was a starry night of such beauty I felt I wanted to cry. Words cannot describe. I took readings through the night with my SQM-L. lightpollutionmap.info suggests this place should be 21.8. In fact no reading I took was less than 21.65, and by 0130 I had a few successive readings of slightly over 22.0! Home in Surrey scores 19.05 at best. Although I'd prepared a list of deep sky objects to get the most out of my still new-to-me 12", I knew that much of the night would be spent faffing: getting things to work properly and re-familiarizing. And so it proved. I had some "finder problems": I'd line up an object with the 9x50 finder on the APM, look through both that and the 12" and not be able to see what I was expecting, only to then waste time hunt around searching randomly. I discovered this morning that one of the bolts on the APM's finder shoe was loose, and the finder was flopping about a little. No wonder I couldn't find anything. I did eventually find and get M3 (glob) in view in both scopes, and the contrast was remarkable. M3 was a definite, impressive and and bright-ish patch of stars in the 105mm APM-LZOS, at 65x, but through the 12" (at 82x): WOW. Sooo bright, so many stars and such vivid colours. It wasn't evident at all in the TS Optics 9x50 finder, mostly because that wasn't actually pointing at M3! I also made good use of my new Zeiss 15x56 bins, and was surprised not just that I could easily see M51 through them, but that it was largeish, not a symmetrical shape and 2 cores were evident. I found out through them also that Zeta Lyrae was a double, I'll have to revisit that one. A few Lyrids appeared. While naked-eyeing the sky, I noticed a very bright and wide patch of stars roughly at the apex of a radial arc made by the saucepan-handle of the Big Dipper: the Coma Berenices Cluster. If you plot the brightest 9,000 stars' RA & Dec coordinates as if they're terrestrial using a Mercator ("Map of the World") projection, you get a mass of dots, obviously (the Yale Catalogue). You can see the plane of the Milky Way easily as thicker stripe snaking its way through the projection. But you can also see a noticeable cluster of bright stars separated from that plane, at about RA12 Dec25: the very same Coma Berenices Cluster. A very nice night, I hope I get a few more like it while I'm here. Cheers, Magnus
  8. And I'd go for bigger .... 18" is perfect for me, lift into the back of a Corsa if I wanted, image scale, wow views....and 20mins set up...go as big as you can, nobody was disappointed with a big dob.
  9. Free lifetime supply of clouds included with every scope sold.

    great observation, Mike
  11. Hello to all owners of this ere mount. Slight issues with my mount on the last couple of outings - namely power related/I'm thinking, Got the mount back in Oct 18 and it ran fine up until the new year. 3/4 sessions. Did not use it for approx 6 weeks or so. Have come to make use if it again and ran into problems. the wifi seemed to be intermittent. When I was able to get my I phone and / or I pad to connect I was having trouble with the alignment procedure. The red light was blinking twice in succession so it was connected to my phone / tablet. Used the north align and also tried the 2 star align option. Found the first star with no issues then the slewing to the second star did not work out. The mount just threw a fit and stopped, To rub salt into the wound I took the mount back inside my garage and it seemed to work ok, given I knew approximately where the align stars were and it slewed round twice as I expected. Weather was not what I class as cold. Would this be power ????? I'm on the same batteries. ( the black and gold type ) That I started with. Was hoping that new batteries would not be required on a regular basis,. Is there a * mains * power option for this mount. Any advice gratefully received. Regards. John
  12. Just arrived today courtesy of @johninderby Just need this rain and clouds to do one now!!
  13. Practicality is the most important aspect for me. Due to my somewhat hectic life, if I owned one, a really big scope just wouldn't get the attention it deserves. It would find itself sitting there woefully, waiting. I used to think that this hobby was all about aperture - granted that is extremely important, but you have to balance that with observing opportunities, lifestyle and storage space. For me, it's these that actually win! Portability is key for someone like me. I used to have five scopes, but now whittled down to just two that actually get used. I find my C8 wonderfully practical, it is just so short but still packs in enough aperture to satisfy me personally at a dark site. When I am at home in the city, it's very good on moon / planets too. I often take the smaller C6N on camping trips - a mere 6" at a dark sky site can deliver some pretty good views. Provided you have the time and storage space for using a large aperture regularly, by all means go for it though!
  14. As you're using the telescope as a camera lens, when you connect your camera, the FOV of a 600mm scope will be the same as the FOV of a 600mm camera lens on the same camera body.
  15. Hi, What problem do you mean ? Electrical, Electronic or mechanical problems ... ... or waiting time until delivery ? If it is waiting time, then well that means something and interesting that people having bought a iOptron get upset about waiting time ... Take it as a good sign because that means iOptron is not a mass produced product anymore or is it ? ... but there are also people who are very proud for waiting a year or more after buying a certain mount brand ... Do the Bells ring ? SARCASM OFF a bit of fun must be ... Have a nice day Rainer
  16. Looks a great little scope Michael, would be good for someone to get use out of it. Ideal for children with its low eyepiece height and would be pretty stable I guess.
  17. So it's similar to dslr lenses, the field of view changes? What size sensor on a telescope would give the field of view as an ordinary lens of the same focal length?
  18. I didn't really notice the stars, but as an afterthought they do look a bit annoying.
  19. Very nice and pleasantly lacking the usual DM hyperbole. Dave
  20. Sorry for the really daft question but I am pulling my hair out. SW quattro 8" If when running a star test the outer of the star is not a perfect circle is this just due to the secondary not being square? I have a funny feeling that the focuser is not square and may need re-aligning, but want to be sure before tearing it apart. To me it seemed the secondary is to close to one side of the scope wall (not on the primary opening side) Last night I tried a star test but for the life of me could not get the secondary to sit centrally in the star. I normally use a baader lazer to get it roughly right then use my cheshire. To be honest I swapped over my ed80 last saturday when I knew we had clear skies, this was my first mistake. I then got in a panic trying to get everything up and running and got myself into spin over it all. Cheers,
  21. She certainly has taken some amazing shots, thanks for posting.
  22. What Peter said, but https://www.firstlightoptics.com/dovetails-saddles-clamps/astro-essentials-vixen-type-photo-dovetail-bar.html should enable you to connect your camera and lens directly to the mount.
  23. Today
  24. Hi and welcome from another newcomer.
