  1. Indeed i saw a good nunber of fotos with the V pointing to the sky and others pointing to the primary mirror.MIne points to the primary mirror but i would like to know if anyone has this particular black type of C8 (photto) and if the V on theyrs point to the primary too.The in -out orientation is more confusing...i can tell you ive made the experience and reversed the corrector and it permormed flaulessly giving tack sharp jupiters and beeing even the best scope on the star party,so to mi its a bit confusing this in out orientation thing :D


  2. Indeed.Ive managed to get the camera to work and have made a test vid and the image is superb,outstanding indeed.Im very,very happy.This whole set was a gift from mi friend Paulo Mesquita and it come with easycap.co.uk . Easycap has a great software and woks well.In terms of image,this camera is in a league completely diferent of the Phillips spc900.I heve great hopes for planetary image for this camera.I will use it ha a all sky camera with fish eye lens too.:D

  3. Hi.Just bpougth a Opticstar CCD cam with Easycap video capture and would like to have your opinion about this cam.How it compares with SPC900 for planetary and how easy is to work with him.Im goung to use this cam with my C8 & HEQ5 Synscan.




  4. Hi astrofriends.I think we all can say its a pride and joy to have an OO scope.Wish i had a Portuguese company making such wonderful machines,i tell you...I think too its a bit unfair,everytime a OO discution pops out,always someone will say how poor the hardware is or some kind of problem.What i see its a company with skills to do any type of scope we want with a degree of optic precision few can match,My dream dob is the Orion Optics 14" F4.5 1/10 wave and they a r e b e a u t i f u l l !!! Wen i saw a 14" 1/4 wave sold here for 850 pounds,my heart almost stopped...You folks should be proud,very proud for having such a good master optician,very proud.I will pursuit my dream of having my 14" OO dob because is my dream and my friends dream at our local club.

  5. THis must be one of the most beautifull and exquisiste planetary newtons ive saw.Believe it or not,another day i was talking to a friend of mine of doing just a project like this.Finding a OTA and getting the 150mm ultra grade Orion Optics set,a good focuser and making the ultimate planetary newton.The mirror cell is so gorgeous...

    Congrats mate,you have mounted a scope that is a work of art

  6. Hi Tim.Yes,the answer is yes,it help allot and the diference is HUGE.Even at home wen defocusing the image i can see the star test hugelly improved with clean airy disc without thermal issues.A simple thing wich can by of great help and its simple to do is to remove the screws you dont use and aply a filter in each.THis can be of great help too and i have in place this sistem too...Every bit helps :)


  7. I friends.Ive made a cooling deviçe from a litle car vacum cleaner and its working very well.Sinçe the corrector cell has two air entrançes hiden behind the retaining ring,i have made two filters for the corrector cell for the dust dont find his way insinde the OTA.Sinçe i whant the air to enter from the back end of the scope i have removed the screws which is used to had finders and othjer stuff and in the holes i aplied filters,-five of them.The air will enter from the sides of the back scope and will pass in the front of the primary mirror and the exaust through the bafles.This sistem is doing an amazing job:headbang:

    Hope you would like the mod.

    Some pics below to better understand the all process





  8. Hi.Maybe on Uk the OO loss value but here in Portugal these folks wen they pun they second hand OO stuff,usually they ask above the selling priçe or close the store priçes and they usualy dont manage to sell them.Its rare to see a OO at a good priçe here and thats a shame.The causes are,-first,OO havent any representation here due to horrendous waiting time for a scope and/or poor quality hardware and any shop wants to take the risk of a nagging client phonning tree times a day to know news.

  9. No its not a dumb question.This is a old photto and the scope take ages to cool down so i have removed the rubber insulation.The cool down issue is by far the unique bad thing SCTs have and im getting the courage to drill some holes into the OTA.Ive tried everithing but nothing works and i dont like fans,-they allways suck dust into the OTA no matter what we do.A passive cool down maybe the answer
