    M13

    From the album: Deepsky Objects

    A total of 2.6 hours of M13 with a NEQ6, GSO 8" F5 and a Nikon D5300. I would like to have the stars more pin point, but it is what it is =)
  2. I`m glad to also contribute to this thread (also not in the way which is preferable ).
  3. Hello again, with this post i just want to contribute to the mono mod statistics. I was unable to remove the cover glass from my D5100 sensor with a soldering ion. So i thought more temperature might help to create a bigger heat gradient. I ordered a pen torch and for about 1/3 around the frame the increased heat of the torch seemed to loosen the epoxy resin. That`s almost the end of the story. In the end i tried for over 3 hours to get the cover glass off. I heated one corner a bit longer (maybe 3s) and the glass cracked... I knew i wouldn`t get of the glass in one piece anymore so i taped it up and started chimping with a scalpel. Long story short, i broke the glass out with an M1 flat screw and i seemed to have damaged one of the bonding wires (maybe this happened at the epoxy sealing step afterwards... i can`t tell). I carried on to polish the sensor just to get a feel for it. This procedure seemed more or less to have worked (at least according to comparison with Herras documentary pictures). I put the camera together again and everything works where the sensor is not involved. So just for statistic reasons. The current score is: technology 1 : 0 me. best regards Matthias

    NEQ6, Nikon D5300, GSO 8" F5. 9 hours integration time.

    I changed the guide scope mounting from the springloaded finder shoe mount to directly mounting it onto the guide rings via a vixen bar. This resolved an elongated star problem that i had.

    I had some trouble with elongated stars on longer exposures. It was suggested that i need to secure my guide scope more rigidly. I bolted the guide scope now directly to the OTA and it seems that the stars problem is solved now.
  7. Hello all, i have a question regarding the cover glass removal. At the moment i try local heating with a soldering ion. However the glue doesn`t turn opaque. In some locations at the edges of the glass i can see that the coverglass is lifting, but the glass itself sits in a frame and i can`t go underneath the glass except at one corner. An at that corner i can`t get the glass to lift. Could it be that the soldering ion doesnt get warm enough? SHould i try to get a pen torch? Thanks for your help!

  9. Hey, i hope that the camera still works and that your CNC approach is successfull! I was wondering: Is there any chance that aceton might work as a solvent for the glue? Not sure if the frame around it is resistant though. I will google a bit Cheers!

  11. Thanks for the advice. I will have a look! I´m currently experimenting with two epoxy resins which i will use to cover the bonding wires (like others also did).
  12. Hello everyone, inspired by this great thread i also wanted to have a mono dslr. I`m not yet there but i have taken my first few steps towards that goal. I received a used Nikon D5100 today which i got for a very good price. I took a few test shots to verify the functionality and immediately disassembled it then. After i reassembled the camera there was one part left over however which you can see here: The camera still works and for today i`m a happy camper. I know that this was the easy part but hey, you can also fail at that My plan is to flash the Nikon Hacker firmware on the camera and do some astro exposures in order to see what true black level and no star eater algorythm does. After that i will disassemble it again and try my luck at removing the CFA.greetings and clear skies!PS:The only thing that bugs me now is that three month ago, i paid 300,- € to have another camera modified although it seems i could have done it myself.

    Inspired by the great "debayer dslr" thread here, i also wanted to have a mono dslr. As a first step i bought a used D5100 and removed the IR Cutoff filter that you can see in this picture. Now the camera would have the label "astro modified". Getting the filter out took me 2.5h, although i have done that for the first time. The soldering part isn`t as dramatic as one might suspect.

    Taken with a Orion ST80 refractor on a Skywatcher EQ6. 24 x 300s exposures with a Nikon D5300 @ Iso 800.
  16. Wanted to thank all the contributors for this thread! Given the current prices of used cameras, i will also try my luck. The performance increase is just too tempting . Before i put my fingers on a DSLR i will first try to debayer an old Nikon compact camera. Clear skies to all!
