  1. Bit of a shameless bump and to say that at this price, there is no further depreciation, so anybody interested is not going to lose any money, just park their funds while using it. I am not going to reduce the price, it either sells at this price or not, but I will throw in the M90 adapter for free. Clear skies, Nicos
  2. Lol, IF that someone shows up! I will venture again into double stacking in about 3 years when I move out of town and set up my own obsy. I will always keep my Lunt 60mm, but a Lunt 100mm double stacked is where I want to end up. Until then, there is so much learning to do single stack!
  3. Hi Ade, Noted, but Étalon needs to go first! Clear skies, Nicos
  4. The Sun is picking up much activity lately as it enters a new cycle and if you are thinking of upping your game, now is the time at a great price for you, especially since most retailers are out of stock!!! For sale is my Lunt 60mm DS module in excellent condition. Comes with relevant literature and Lunt carrying case. I decided that I want to release funds for another project and I also like my single stack images well enough to stick with single stack imaging for quite some time - and learn more about post-processing before attempting double stack imaging and processing. The DS Module new is £2,281 and I am quite happy to let it go for £1,140 delivered – 50% of new price. Shipping will be with tracking and insurance via TNT Worldwide. For another EUR 80 if interested, I will include the M90 rotation adapter which makes aligning the DS module a breeze and safer than unscrewing it a tiny bit (as most do). Clear skies, Nicos P.S. If the slight dust that shows up on the parts annoys you, I'd be happy to use a rocket blower to get them completely cleaned out!
  5. I am not claiming that the CN approach is the best. What I mentioned is that it was the most workable we could find. I am not trying to be controversial, but stacking the next day means you just got the data one night and viewed it the next day, so it is not close to live. My 2c and feel free to ignore. The point of amateur observational astronomy is to actually observe. How it is done is up to each person...
  6. Agreed and noted. On CN we had to reach a critical volume of both topics / posts and number of active members before taking action... How about using tags for NV related topics?
  7. A 219 euro device is no competition for modern white phosphorus devices costing at least 30x more for the bare minimum. Now, if your aim is to see some wild life at night and at relative close proximity, this device (the Omegon) will do. It works with an infrared illuminator, so quite different to the devices used for NV...
  8. NV devices as they are used, do not by themselves stack images. Rather, they enhance in real time. Sure, you have phonetography for NV, but that is just to convey what is seen and it is not the means by which NV is practiced. Traditional EAA is either say one very long image where photons are stacked over time, or some short images which are stacked. "Traditional" EAA is near real time. NV is real time. Disclosure: I only do "traditional" EAA. My stacks are in the order of 10 seconds of anything between 10 to 20 frames. Yes, I have a "usable" image to observe in 20 seconds and then it just improves with more stacking. But NV - it is instant, at the eyepiece. I guess that is the separator - for the time being with current technology - that NV is real time - 0-100miles in a fraction of a second real time - electronic enhancement at the scope with an eyepiece that includes all electronics Vs traditional EAA which is near real time but not quite there, and employs much additional gear.
  9. Sigh, being admin on CN means that I had to go through recurring bouts of trying to define EAA / EEVA / NV. These were the great EAA wars on CN. What came out of it: EAA is viewing without an eyepiece, doing any enhancements available in real time and while one is observing (applying calibration frames real time, tweaking software display options, cooling etc). Anything done to the actual image after observing (post processing) is considered imaging. As an avid EAA practitioner, this is how I see EAA. I do both traditional viewing and EAA viewing and I consider them complementary and I also consider myself lucky to have options available. NV is traditional viewing with an eyepiece, but that eyepiece offers on the fly enhancements. There are no laptops involved, no ASIAir Pros (love mine), no external power packs, no cables, no CMOS or CCD cameras, nothing else except slotting your electronic eyepiece, or doing afocal NV and immediately just observe. It is different enough to EAA to deserve its own classification, as the equipment used is wildly different and techniques used are wildly different. Feel free to ignore my opinion of course, but I do wonder why so much energy is devoted to define how one observes. There are a host of different opinions, but in the end, as this is a privately owned forum, the admins will decide the direction they wish this place to follow. I would vote, if a vote was asked for, for a separate NV forum. Why? Observations are conducted differently, equipment discussions are completely different and the end result is quite different too. My 2c
  10. Just some good healthy (need that vitamin D!) fun with the Sun. Two of the photos are over processed to show some features clearer. Wishing everybody happy holidays
  11. Here's some more examples EAA style, again, 7 x 10sec Gain 350 no calibration frames from the same evening as the previous ones I posted (so please take into consideration full moon). Pacman, NGC6888, Heart and Soul nebulae. Yep, a great little lens and FLO has them well priced too. I am tempted now to get the 200mm f4 lens since I repurposed my ASKAR 180 as a finderscope. Deep Sky Dad has EAF autofocus kits available as well!
  12. Not that much I would guess, as you are not pixel peeping at that focal length and image scale...
  13. I forgot to take a screenshot later in the stack, but noise dropped dramatically shortly thereafter. My point being, that while pixel size is a bit "largish" and pixel scale again, "largish", the camera can and does perform well under the constraints set by short focal length instruments, as evidenced by the lovely images in this thread (excluding my own as I do something different).
  14. I only do EAA, but considering a full moon and only 7 x 10 second frames stacked via ASIAir Pro and no calibration frames, the camera delivers. I used the ASKAR FMA180mm lens at f4.5 with the ZWO Duoband filter. No post-processing, this is straight out of a screenshot at the 70 sec mark of a live stack view.
  15. Math is correct: Pixel size of camera x 206 / Focal length = 3.76 x 206 / 135 = Resolution of 5.737
  16. Just ran into this topic - nice images people! - and if of any use to anyone, Teleskop Service put this up on their site a couple of weeks back: Wega Tube Rings with Finder Shoe and Dovetail Bar for Samyang 135mm f/2 Lens
  17. Well, you DID ask. All about 60 to seventy second integrations and under a full moon on the same evening, same gain and 10 sec exposures stacked....
  18. I only do EAA, so take with a pinch of salt: NGC7000 7 frames x 10 sec each at 320 gain, ASI533, ZWO duoband filter. No calibration frames.
  19. My contribution to this thread: I upgraded my zero mount with the WO vixen clamp and the Desert Sky Astro extension (at the end of the page), although the SkyWatcher extension should do nicely too. Currently expecting some knobs from ADM to complete the look. Also I am thinking of adding a small handle at the bottom of the mount by tapping it. I have a handle from my DM-4 mount that I shortened already and that I don't use - it would be an easy mod.
  20. You also need to consider 4.3% optics tax and VAT when you take the OPT price and adjust for European prices...
  21. Sigh, added to the bucket list!

    Geoff, I need to stop being lazy and try my hand at double stacking. Filter has been sitting in its case for a year because I more or less enjoy single stack and I am lazy. But, if I want to get more detail in my images, I need to break out the DS module asap!
