  1. No problem. I'll keep you posted after the second night. The weather is bad for several days. I wait for better weather conditions. Florent
  2. Hi all, On August 14th, i received my new mount from my french dealer Pierro Astro. Pierro Astro is one the only dealer in France to realize a free test + optimization + adjusting of your mount you purchase him. He delivers a complete report in the package with all the procedures realized on it. After 2 weeks in its hardcase, the mount has been installed in my backyard after a preparation of my observation spot. The mount will stay outside and with all protection against the weather. One week ago, i tested my new mount with one of my 2 CCD setup. The setup was my ASA 12" f/3.62 newtonian OTA modified with the OPTEC TCF LEO Split-Clamp Low Profile focuser + the SW EVOSTAR 72ED guide scope + my Moravian G4-16000 CCD camera + my ZWO ASI120MM Mini guide camera. I tested the setup with N.I.N.A 1.10 software and GS Server (Eqmod alternative). No problem. About the guiding, the first part of the night was not good because the PHD2 adjustments were not correct. After adjustments the guiding was very good at the end with low curves. A second night will be necessary to confirm that and i will post you my results obtained. For this second night, i will try to use the new USB HUB on the EQ8-RH to avoid to have cables get down. The silver counterweight is a Geoptik of 5kgs. All the main outside screws on the head and on the tripod have been replaced with INOX A4 screws : Stay tune........... Florent
  3. Hi all, This is my first complete LRGB image taken with my ASA 12" newtonian reflector and my Moravian G4-16000 CCD camera. I equiped my ASA with a low profile focuser, an OPTEC TCF LEO Split-Clamp. It has replaced the native ASA OK3-Z focuser who had a lot of mechanical problems. The LEO is strong and stable with the large 16803 sensor. I took 6 nights of exposures on the NGC4725 galactic field. All the information are in the dashbord. I give the link for the Full Resolution image too. FULL RESOLUTION image here : http://www.poigetdigitalpics.com/Fichiers_Divers/LRGB_NGC4725_R1G1B1_2_DBE_DBE_DBE_Spikes4-Modifier-Modifier2.jpg Enjoy ! Florent
  4. Hi guys, This summer, i have the project to have a permanent mount in my backyard. My instrumentation is one ASA 12" f/3.62 (1086mm) carbon newtonian OTA with a Moravian G4-16000 (KAF-16803) CCD imaging train + one SW EVOSTAR 72ED guiding refractor. I would like to know your opinions about the quality of these 2 mounts for long exposurses, guiding, manufacturing quality, resistance of materials to humidity (screws, different parts of the mount.....etc), mounting with a Losmandy DUP..................etc. My choice will be for one SW EQ8-R or EQ8-RH (with RA encoder) or for one iOptron CEM120 or CEM120EC. And is it better to choice the standard version vs encoder version for these mounts, especially for the iOptron CEM120 ? Thanks. Regards, Florent
  5. Hi Martin, My ASA 12" is from year 2007. The native focuser was a JMI NGF xTn 3" replaced with an ASA OK3-Z. My OK3-Z was catastrophic. The OPTEC LEO is an incredible focuser for imaging. Florent
  6. Hi guys, After my TeleVue NP101is ( http://www.poigetdigitalpics.com/photo-equipment3.html ), i decided to change the focuser of my ASA 12" newtonian reflector. The native focuser was the ASA OK3-Z for heavy imaging train. But i had several big problems with it, mechanical problems, impossible to do automatic focusing, backlash..... etc. It was impossible to me to use the huge KAF-16803 chip of my Moravian G4-16000. And with the mechanical problems, i had a shifting of my imaging train inside the OK3-Z focuser and the CCD chip was not aligned with the optics even if my collimation was great with the CATSEYE kit. After several nights of tests and when i found the real problem, i decided to change the focuser by a high-end focuser : a low profile focuser. 2 choices : one FLI ATLAS as on my TeleVue but very expensive or the new low profile focuser on the market released by OPTEC, the TCF LEO. The LEO specifications are the same that the FLI except for the price, the LEO is 50% cheaper. After a few mails with Jeff from OPTEC, i ordered their last version, the Split-Clamp, of the LEO designed for heavy Wynne 3" corrector for newtonian. I calculated the effective length for the adapter installed between the ASA OTA and the LEO focuser. The adapter has been made by Precise Parts in Florida. The last weekend, with the Full Moon, i installed and tested the OPTEC TCF LEO on the ASA 12"N f/3.62 . All is OK now with a high precision Auto focusing. I can use my 16803 chip now on my newtonian. A few images of the mounting : This is a test of 300sec of subexposure taken with the G4-16000 CCD camera / ASA 12"N f/3.62 with its ASA 3" Wynne corrector / OPTEC TCF LEO.

  7. Hello Olly, Thank you. ? I live in the Loiret (45). I am 5km of Pithiviers and 40km from Orleans, 90km from Paris. My G4-16000 is optimized for my Televue NP101is for large fields. Now, i optimize it for my ASA Newtonian. Florent
  8. This is one only 5min. of sub exposure processed. Can you confirm that is the M87 jet ? Florent
  9. Very nice details in the galaxies. The processing is soft and good. Florent
  10. Thank you all ? I hope to continue this image and to take short exposure to see if i can show the M87 jet. Of course i keep you posted about it. Thanks. Florent
  11. Thank you so much. Optimized this instrument with a huge CCD chip is very hard, but after a lot of effort the results arrive. I wait a clear sky to continue this image and to take the RGB frames. About the CCD Acquisition information, i created it with MS Word. Here in France, several amateurs has created similar things but not clear to me. I created mine with the essential information. Thanks once again. Florent ?
  12. Hi guys, This is the first lights of my ASA 12"N f/3.62 (purchased in 2007) with my Moravian G4-16000 CCD camera using one KAF-16803 chip of 36mm x 36mm (4K x 4K). The adjustments, collimation, ASA OK3-Z pression screws, asked a lot of attention. For a precise collimation, i use the CATSEYE XL & XLKP kit. This is the first 3hrs of exposures taken the last weekend in one night. The second night was too windy unfortunately.

  14. Thank you Richard. Oh yes, my picture of King of Wings. I used my Nikon D750 Full Frame with my Samyang 12mm f/2.8 fish-eye AE FF lens. ? Florent
  15. Thanks Paul. About the diffraction, maybe the optics of the TeleVue or maybe the CCD chip of the G4-16000. I had these diffraction on the fits images. Florent
  16. Thanks Scott. A lot of work to achieve these results. ?
  17. Thank you. I hope the weather will be better, i would like to take new pictures with my G4-16000 and to continue my tests with my ASA Newtonian reflector and this camera.
  18. Thank you Guys for all your welcome ?
  19. Hi Guys, I present you the second image taken with my Moravian G4-16000 camera mounted on my modified TeleVue NP101is. Images and technical information below.

Florent
  20. Great image ! The second has a very good colors but the first has more details. But the both are well defined. Your RC works fine ? Florent
  21. Thank you Pieter. Oh yes, the new imaging train is solid as a rock to support the big G4-16000 and the FLI ATLAS focuser. The TeleVue NP101is works perfectly now. ?
  22. Thank you. Steve, i am a newbie in the planetary imaging. That's only my first shots. I never took planet images before ?
