Date Taken: 03/13/2014
Location: Prawet district,Bangkok,Thailand
Telescope: Orion SkyQuest XT8g Computerized GoTo Dobsonian Telescope
Other Camera: DMK21 AU618
Processing: FireCapture2.2,Winjupos10,Autostakkert2.0, Registax6, Photoshop CS
Exposure: 180s @ 60 fps Red/Green/Blue
Other Equipment Used: Orion Nautilus Filter Wheel 7x1.25, Orion shorty Barlow lense 2x, Chroma Tech RGB filter
Notes: This is a Saturn image. You can easily see the ring and division. For combination of all equipment, ORION SkyQuest XT8g play a major role. After best mirror collimation, some of ambient temperature must be adjust before picturing process begin. With the PEA on SyncScan, I can handle a 6 meters of focal length (for other pictures) with some simply additional adjust by hand controller! I also love the dual speed crayford focuser of this telescope. It help me on a very precisely fine tune of image sharpness. Very easy and advantage, if comparing to ordinary focuser! Actually, I want 5x barlow lense. However, I use ORION Shorty Barlow 2x due to a low brightness of Saturn. Then, ORION Nautilus Filter Wheel 7x1.25" is mount on the barlow. I use Chroma Tech Red/Green/Blue filters for minimize an image focus shift. Finally, the DMK 21 AU 618 is selected as a camera. The camera can reveal top of ORION telescope optic quality. Fire Capture 2.2 is used for control both of camera and filter wheel. Both of them are work well on ASCOM platform. I highly recommend to use the Nautilus filter wheel. ORION provide a completely support on manual and every necessary software. You don't have to guess or try on every unknown driver or ASCOM compatibility like some other products. You can find them all on a well categorize download module of ORION website. Fire Capture controls a series of imaging process. Begin with picturing of 180 s. @ 60 fps of Red, then pause 10 s, change filter to Green, then begin of 180 s @ 60FPS, . . . . continue until finish all filters. It really nice and simple to use this software to control all imaging process. I love it! After I get raw VDOs, the VDO must be process for derotation, which is a major of Winjupos 10. I derotate all of the VDO, then use AutoStakkert2.0 with drizzle 3x to increase image size and image stacking process. Sure that all of stacked images still have only grey color. I then recombine RGB picture on Winjupos 10 again. Then, I use Registax6 to sharpen image. And finally finish picture by Photoshop CS, stretch level, contrast, brightness and picture information.
