Martin-Devon Posted January 5, 2016 Share Posted January 5, 2016 I was not sure whether to post this or not, since it's the first "test" image with my new Moravian G4-16000 (Kodak 16803 chip) on the TakFSQ106, and as yet it's not optimized in terms of resolving tilt or focus, and the data is rather minimal & low-ish quality. This is just a single frame, that's the beauty though, the capture FOV is tremendous. What's a little more challenging is working with data from 9 micron pixels and 3.5 arcsec/pixel resolution - as I'm finding, I have to handle the processing differently to the data from my QSI690 (3.69 micron/1.98 arcsec/pixel), and I've tripped up a few times on this, you'll easily see that the M42 part of the image is pretty naff! With this big chip, good calibration frames are critical as well and I need to put more attention to optimizing my flats.Anyhow, I've always yearned for a wide-field CCD, and this is a starting point, now I have to put the leg-work in and buckle down to getting the best out of it and pay more care with the processing. A quick 'thanks' also to Chris Heapy (ChrisLX200) for advice and sharing some of his initial G4-16000 data with me before I purchased.Data for this test image is just 8 x 10min H-alpha, taken on New Year's eve last week.Thanks for looking,Martin 16 Link to comment Share on other sites More sharing options...

Barry-Wilson Posted January 6, 2016 Share Posted January 6, 2016 Ooohhh, excellent Martin.I can see you're going to have a great deal of enjoyment from that FOV . . . recommencing your Simeis 147 project?Good luck and can't wait to see how you progress. 1 Link to comment Share on other sites More sharing options...
cfpendock Posted January 6, 2016 Share Posted January 6, 2016 That field of view really is pretty incredible. Nothing wrong with 3.5 arcsec/pixel for an image of this size. I presume you used the wide angle lens for this? In which case I am amazed there doesn't appear to be any sign of vignetting. It will certainly be interesting to see what else you can do with it!Chris Link to comment Share on other sites More sharing options...
tony210 Posted January 6, 2016 Share Posted January 6, 2016 Great image - monochrome images have a special subtly I think lost in colour images - best wishes Tony 1 Link to comment Share on other sites More sharing options...
Martin-Devon Posted January 6, 2016 Author Share Posted January 6, 2016 Thanks everybody for your comments & feedback.Barry - at the moment I'm just getting used to exploring several targets to see what fits in. I've had a quick look at Simeis 147 (SH2-240) and amazingly it all fits in nicely into a single frame, so if the weather breaks, I may have a pop at this one. I recall spending around 8 nights over the Christmas period of 2014 trying to put together a 9 panel mosaic of Simeis 147 and failed miserably since conditions and level of Moonlight varied greatly from night-to-night making consistent quality & gradients a huge issue.Chris - this image was taken just with the Moravian CCD, there was no DSLR lens or similar bolted on - I know that some folk successfully use hybrids of a CCD/DSLR lens but there's no need for that with this CCD since it's a full frame chip of 36.9 x 36.9mm.There's lots to still bolt down and optimize with this new set-up though. The Moravian 7-position filter wheel takes 50mm square filters, and I still need to order the rest of the narrowband set before I can do any colour images; the motorized filter wheel itself is very reasonably priced though, just a tad more than the Atik EFW2, yet it's the size of a dinner plate! The supplied Moravian OAG also works very well with my current Lodestar guider, and guiding traces in Maxim were remarkably good, so as a package the Moravian OAG/FW/CCD goes together very nicely.

MartinSorry, I should have been more clear, I had noticed that you used the Tak106, and wrongly used the expression wide angle - I meant reducer....Wow - 50mm square filters - I presume to avoid vignetting. Astrodon? !!!!Chris 1 Link to comment Share on other sites More sharing options...
Martin-Devon Posted January 6, 2016 Author Share Posted January 6, 2016 Hi Chris, this is all at native imaging, no reducer is used - fortunately the Tak106 has a massive 88mm imaging circle and can handle these full frame chips, whereas the babyQ (Tak85) would struggle here. The 50mm square filters are amazing, I have the Astrodon LRGB set and a single 5nM Astrodon H-alpha filter so far - the prices are shocking though! The flats show a little vignetting, but it's fairly minimal and easily corrected with flats. I think it helped also that I kept the imaging train at M72 from the Tak stock focuser right up to the M68 OAG, where I had to order a custom-made adaptor from PreciseParts in USA to link it all together. Appreciate your interest and comments.Martin 1 Link to comment Share on other sites More sharing options...
