Ambitious plans for the Moon
WARNING! 16 megapixels of the Moon!
Ambitions have been higher. I planned to make a panoramic assembly of practically full lunar disk @4750 mm of effective focal length. But I rapidly ran out of
fuel disk space and went astray at the very same time. So to get some outcome, I have lowered EFR 2,5 instances (falling down to 1500 mm) and created this one – ~16 megapixels of the Moon and a bit of cold void about, constructed of 21 GB of raw information in 32 panels 🙂
Aquisition time (begin of the session) : JD2456851,36642361 (13.07.2014 00:47:39 MSK).
Image orientation: practically true
QHY5L-II monochrome CMOS camera through 2x Barlow lens Celestron OMNI XLT 150 mm Newtonian riding Skywatcher NEQ-6 Pro SynScan mount.
Aperture 150 mm
Native focal length 750 mm
Successful focal length 1500 mm
Tv = 1 ms
Av = f/10
Computer software: FireCapture
Exposures: 300/600 x32
Processing: movies was processed in Autostakkert!two. Resulting images ware were stitched in Microsoft ICE. Resulting panorama was sliced in 4 2500×2500 pix panels. AstraImage has troubles handling Massive images. So panels were separately subjected to Richardson-Lucy deconvolution in AstraImage three. (Gaussian kind PSF, size 1,6 units, 7 iterations) and deconvolved pictures were stictched back in ICE.
Of course, final touches were made in PS and involved some contrast stretching and tone curve adjustment.
Notes on QHY5L-IIm CMOS camera:
Most attractive attributes have been eye-piece design (with dustcap on it appears like a 35 mm film canister for me :), 30 fps at complete resolution of 1280×960 pixels, higher QE and each and every-pixel-worthy monochrome sensor. Create-in guide port would come handy a single day also.
Of course it fits nicely into PST’s eye-piece port and gets the focus quickly with out need of cumbersome adapters. Barlow lens can be employed also. 1 just requirements hi-class luxury lens with compression ring not to scar the camera housing with fixing screws (my Bresser 5x SA Barlow is of that class :).
Regrettably, in combination with PST it seems to be vulnerable to Newton ring’s pattern that originates someplace inside the telescope. Interesting – where is this "somewhere"? The only way to get rid of it is to let the Sun drift across the field of view, so any steady patterns are lost in stacking, while moving particulars are preserved. It’s a PST-Sun exclusive issue.
Of course it is neglectable size and miniscule weight make it easy to balance the setup but adds a need of obtaining a personal computer nearby the telescope and thus some extra cables. Effectively, foldable table, a chair and mount’s remote controller make the session rather comfy.
Design and usability: cool!
Speed… Surprise! Some capturing softwares, like EZPlanetary (QHY’s personal) and FireCapture, support .RAW readout, that benefits in 16-bit .ser files. Really nice. Of course the speed is restricted to about six fps in this mode. In standard mode – eight bit monochrome – with some tweaking, which includes adjusting disk write buffer size (FireCapture supplies a tool for figuring out optimum) and choosing proper port I was in a position to get 15 fps, which can be turned into 30+ by specifing region of interest say 800×600 pix. But still it’s not promissed 30 @complete resolution. A difficulty to be solved.
Speed and overall performance: satisfactory+ 🙂
Sensor’s functionality… 1 ms shutter speed and 47/1000 obtain at f/10 with the Moon as the target. And no Baeyr’s pattern that minimize the successful resolution twofold. I like it!
But! Nonetheless I’m still unable to capture solar prominances along with surface attributes. Needs to try couple more instances.
Sorry for apparent wordiness 🙂
