  1. Past hour
  2. thanks Dave, im doing me best but everytime i think im beating it it keeps coming back with a vengence. clear skys. charl.
  3. thanks David, sorry ive been so long replying but this darn flu put me in me bed for a couple of days, hope i havnt missed much. hope you have had some clear. id like to say im feeling better but i still feel like death warmed up . charl.
  4. Yep... the same always happens to me! I usually process at home on the notebook and get scared once I check the final result at Office But in your case, it is Very good short RGB result during Full Moon even a galaxy is slightly visible at the bottom P.S. happy to see your new cam does the job as expected.
  5. two drops of condensation moving due to gravity on the flip? I don't know but just throwing out ideas
  6. 3.5mm TeleVue Nagler 82º Eyepiece price dropped to £150
  7. Instead of bathroom sealant, use a liquid gasket (https://tinyurl.com/y5wokj3a) They are meant for much harsher environments than we use....
  8. This is ment to be some weird sort of "out of scale with itself" cut away drawing so intoxication might have more consequences in the final build than pictured, do take plenty of money I think the drinks may be pricey and so will the valae parking...
  9. I imaged this nice barred spiral galaxy already 6 years ago with budget 6" newtonian, and it was one of my spring targets for 2019. I managed to gather luminance at the beginning of April, but then I needed to wait three more weeks to collect RGB channels, and unfortunately Moon was already present then All photons collected in my suburban astro shed (NELM about 5-5.5mag at zenith). Meade ACF 10", CCDT67, QHY163M, EQ6, LRGB 290:40:30:30x60 seconds (gain 100), seeing moderate, transparency good.
  10. I fully agree, and it is also much more forgiving on the mount. That's why I started with an ED80 on an EQ5 and a Canon DSLR. Furthermore, due to its popularity, the ED80 is easy to find used and retains its value very well. Just remember you need a flattener with it. Fabio
  11. Long focal lengths require really good tracking and guiding. It's not something you want for a first scope for AP. When your starting getting everything tuned with a 600mm frac is hard enough. There's so much to image between 500-600mm , to the point where some objects are too big even for that. Long focal lengths are hard to guide Really fast scopes are tricky to focus and tune. Neither are where you wanna start your journey into AP. Theres a good reason something like the SW ED80 is a popular scope. It's punching above it's weight in quality and it's very forgiving when you start. If you go too long or too fast you could end up frustrated and spend most of your time getting setup.
  12. Just to add, there are pros and cons to using camera lenses with smaller sensors. While much of the image circle is wasted lens aberrations and vignetting are less noticeable because the corners are cut off, sometimes the lens needs to be stopped down half a stop less which produces a brighter image. Also, depending on the target, the smaller field of view may not be important. The 1600MM Cool, with its small pixels, is a good match for lenses in the 135mm-200mm range. Even 135mm is enough to resolve good detail on many DSOs, note the dust pillar on the head of the Pelican in the image above.
  13. Today
  14. The Rokinon 14 f2.8 (or Samyang, it's the same lens), is a great lens for nightscapes and widefield images of the milky way. To help you with your budget, it's quite easy to find one used, just in this case check which version you find, as there are quite a few around (at least for the samyang). I noticed that the Field is not fully flattener (can be expected for such a lens) and stopping down a bit improves star shapes. Fabio
  15. A bar on the ground floor?. I'd never make it to the scope, because the stairs on all floors don't connect.
  16. Just tested the top of the case that was sealed and found a leak. That part was not as well sealed as the other parts.

  18. Hi. I removed the list; hijacked threads. It's sad when equipment becomes more important than astronomy:( Cheers
  19. Hi David, Try this with your ASPS. Try to RUN the ASPS as ADMINSTRATOR.. Klick on ASPS ICON and then with your Mouse LEFT BUTTON and then RUN AS ADMINISTRATOR and then try to solve the image you have. you need to perform this action only once, once SOLVING works and also the LOG-FILE is created, you can start to use ASPS normally " not as ADMIN " Try it please.. And please do not forget to install the INDEX FILES for your FoV.. Good luck Martin
  20. It was Chris, thanks. I was a bit surprised there wasn't more colour too, same for Izar. Not sure of the reason as the transparency looked pretty good.
  21. Good fun Stu! I use my ED80 for similar quick sessions sometimes when I've got an early night, or we've got guests wanting their glasses refilled. I'm surprised that Algieba was bleached out with the 62mm - with 80mm the pair are definitely orange. Chris
  22. Mine must be fiftheen years old its the single best accessory I ever bought. It looks battered but works like new.
  23. When I popped out to put the bins out and make the bunnies fox proof last night, I noticed the sky was very clear and dark ish for round here. The weapon of choice for this, another of my micro sessions was the Tal Alkor 65mm Light Thimble, on my Ercole mount, and I just thought I would grab a few doubles before my dear lady questioned my absence! Four doubles; Algieba, Castor, Polaris and finally Izar. The Alkor has three options for magnification, x33, x88 and x133. I used the lowest as a finder power and them switched to highest. Algieba is a mag 2.2 and mag 3.6 pair at 4.6" separation. Their colour is listed as orange, but they appeared white to me. For such a small scope, the rendition of the stars is wonderful. Beautiful bullseyes with one diffraction ring. They were clearly separated and the magnitude difference was clear. A lovely sight. Castor was not dissimilar actually. 1.6 and 3 magnitude with a 5.2" separation, again beautifully resolved as two white, uneven bullseyes. Polaris was much more difficult, to begin with I didn't think I would get it, but on a few occasions when the seeing stilled I caught the tiny mag 9.1 secondary, right on the limit for this scope under my conditions. The Mel Bartels calculator gives between 8.8 and 9.8 for this aperture under mag 18.5 skies, so I'm confident it was doable. So finally Izar, a good challenge for the Light Thimble! Again, when I first looked I couldn't detect the secondary, just an unsteady diffraction ring. However, after careful focussing and observing for a little while it was clear that the secondary was buried in the diffraction ring (I've seen this effect on Izar before) , and was present in the correct position (verified later). One trick I've tried with the Alkor before is to pull the eyepiece out of the extension a little and the extension out of the Barlow. This gives a bit more power, I'm guessing at x150 or x160 and the secondary became clearer once I had done that. I didnt get the same sense of colour as I do with a larger scope with these two, the secondary just looked duller than the primary but I was just happy to get it at all. This scope really is amazingly sharp, 60 times mag per inch or there abouts is pretty impressive, and the star shapes are way better than many larger dobs I've used. Without making any permanent changes, I've removed this Alkor from its normal mount and fitted it with rings, albeit Munsen rings which are the only ones I could find to fit! Fitted to a short dovetail, it rides on a standard mount very nicely. I've also fitted the shoe for a Rigel finder which makes life much easier than the standard two part rifle sight. So, another something and nothing report from me, just trying to keep my eye in and enjoy a challenge with whichever scope I manage to get out for 15 mins
