  1. Hi there! Again, just for sharing with you my last attempts with my current setup based on a Maksutov (100/750) (brand "MTO") used in afocal mode (with a 40mm eyepiece, or a 24mm one) with a SiOnyx Aurora Pro, or in prime focus with a ZWO ASI 290MM "mini". https://www.youtube.com/watch?v=MA_Nz-Yl6rQ&t=11s https://www.youtube.com/watch?v=I0CCtAJELM8&t=28s https://www.youtube.com/watch?v=HWx2Dinf9EI&t=70s https://www.youtube.com/watch?v=xBtxja5ddok&t=137s Just a lot of fun with a quite minimalistic setup, in azimutal mode, without tracking. Best regards! Lambda
  2. Hi there! While taking my coffee in the afternoon, yesterday, i started to look at the sky, the hand in the pocket the other with my cup... Then i said to myself: "well, where is the Moon right now? I guess, it must be over there.....", while looking well, I found it, but with the blue sky and big Sun, it did not jump to the eyes (at least to mine... ), so i said to myself afterwards "let's try with one of my Guizmo, perhap's i will see better, especially in the near infrared....". Coffee gulped, here we go! Here is the Guizmo: https://www.youtube.com/watch?v=Z9UDMI4v-KA&t=16s and for the Moon... https://www.youtube.com/watch?v=FXmKdvCGUKQ It was an easy session, a cool coffee break ! : Clear skies. Lambda
  3. Hi! Thank you M40 for your appreciation. This camera is a true "swiss tool" for our hobby, definitively. you can design, from that, a grab-ad-go setup quite easily. Indeed, a good "budget" alternative to the classical NV tubed solutions. Next coming days, i will try, if the weather allows me, to point the young Moon with this setup... Regards.
  4. Hi there. Here is a simple desire to share with you a cool E.E.V.A. session made last night for testing a set-up based on an afocal coupling between a MTO "100/750" and a camera SiOnyx Aurora Pro... Short description of this set-up plus first terrestrial tests https://www.youtube.com/watch?v=Z9UDMI4v-KA&t=7s And here a kind of feedback during this last night https://www.youtube.com/watch?v=RV-RhX4t64w Nothing exceptional, but just a simple manner to enjoy our hobby. Best regards. Lambda
  5. High scotty1. Thank you for your input. It may be indeed the origin of such lights. I keep on "investigating"... The fluctuating and occasionally not totally homogeneous aspect are also intriguing me. The lightning activity was not expected in the weather forecast in my area at this moment. I was surprised to see it occurring this night. Here two more extractions..... Regards. Lambda
  6. Hello, Just a short passage for sharing with you an observation i recently made with using a camera SiOnyx Aurora "Pro" for a time lapse. I was lucky to catch some interesting lights occurring in my urban sky during this session. Details are in the videos. Do not hesitate to share your thoughts about the origin of such lights. And the original video. Best regards and clear skies ! Lambda
  7. Hi Xio1996, Thank you a lot for your kind words. I am happy you enjoy it! Best regards and clear skies. Lambda
  8. Hello again. Here is some observations made last week in a nice remote area in France, offering a very pleasant sky, and chilly conditions. Best regards. Lambda
  9. Hello. Just a short passage for sharing with you a little EEA session recently made on my urban balcony, before sleeping... Thank you. Best regards. Lambda
  10. Hello, Robert, thank you for your feedback. For the "scopes" i am using, take a look in the description, everything is disclosed there... Shortly said: for one camera, one lens is 160mm/2 (ex: USSR "LOMO", projector lens) and for the other camera, a lens 6mm/0.8 "COMPUTAR". Cheers. Lambda
  11. Hi there! Just for sharing a little EEVA session in "video" mode/almost real time, with some short live stacking session, zero post treatment..... 15 mn of "real life" EEVA observation on my chilly urban balcony before sleeping..... Setup based on two ZWO ASI 290MM "Mini". Details in the video. Cheers. Lambda
  12. Hello! Well, after a stupid mistake where I found a way to burn all my video line on my camera: the Runcam, the DVR, the screen, by plugging by mistake the "red wire on the blue wire", i decided to revisit the aforementioned camera by simplifying it and replacing this video line which was used as a wide field viewfinder, by a second 290 MM, which allows me to remove a screen, simplify/secure the power supplies, and take advantage of the SharpCap and Asistudio functionalities for the two cameras.... In short, it gives at the first tests, that. Quite convenient, nice to use "on the go" ..... The two 290's are running well in parallel on the mini PC, tested in 24 fps, to see if it doesn't freeze... perfect.... The last step is to provide me with a portable power station delivering a clean 220V AC, to be placed next to the tripod, for future nomadic sessions. This is becoming, step by step, the "Swiss Army knife" of astro/terrestrial observation that I wanted..... :dance: Next session will be more dedicated to video observations of astro targets. Best regards. Lambda
  13. Hello. Tombardier, according your questioning, it may be possible to see two specific aspects and manner to proceed: (1) If you wish an optimal results, with awesome views through your scope, with the "wahouu" effect, indeed, try to look after the highest ranking tube you can afford. It would mean that the best option would be to be patient and spare as much as you can for obtaining the "Holy Grail" tube, with the best specs according the now-day standards. In Europa, at least OVNI Night Vision would be a solid provider in this sense, definitively. In United States you will find also good bunch of dealers (take a look on CN forum). In Asia, take a look to a company like Hamamatsu (JP) for instance...... (2) If you are, and you know that you will be anyway, limited by your budget on a long term, and you wish anyway to plunge, as fast as possible, in the night vision adventure, than try to find the "less bad" tube you can afford. And apparently you are capable to do some machining, which would allow you to save more budget on the tube purchase. On one hand: In this second option, practicing a DIY manner would bring a lot of good teaching for you. But indeed at a cost of a potential limited performances, it will be unavoidable. On the other hand: even if you buy a sub-optimal tube, try to enjoy it, because even with modest specs, it will bring some enhancement in term of sensitivity for your astro or terrestrial activities. Shortly said, even a worn old gen 2/3 tube bringing only remaining "few hundred of uA/lm" compared to the original PC response, would be sufficiently potent for enjoying some astro/terrestrial NV. Especially if you build from scratch your own system. Just the "whaouu" effect will be, indeed, more humble/modest. Do not forget that "NV" astro was initially practiced by pro astronomers since decades (even starting from the first half of XXth century: Lallemand camera) with using PC materials having incomparably lower photo electron emissiivity capabilities (few dozen of uA/lm...) relatively to what can provide even a old "modern" second hand gen 2/3 tube... Shortly said .... Just keep in mind that, by buying a second hand tube, you will not reach the perfs given by the tubes involved in the option (1), that it..... But, if you follow this path, try to enjoy anyway what you will have between your hands, and to focus on the learning process.... Also, try to question as much as you can the potential seller and to check if there is, at least, no "hidden defect" Good luck for your project and your quest. Lambda
  14. Hello. I wanted to share with you some recent "observations" i made while testing a camera SiOnyx Aurora "Pro". It is mainly shooting stars and meteors, but also some timelapses...... This camera has IMHO a great potential for EEVA activities, and if it would be possible to use it in prime focus by removing the genuine lens (apprently a possible DIY mod) , it would be even greater! Enjoy, Clear skies. Lambda
  15. Hello. Here is a small collection about my last EEVA session last night. Details are in the description... As usually, when packing the material, at the end, for coming back at home, a huge bolid was crossing the sky with a trail and a yellow color quite impressive... Too late, everything was packed.... Best regards. Lambda
