M51 with mono DSLR

[frostynixon]

Hello everyone,

i want to show one of my first images taken with a mono modded Nikon D5100. It`s not the ideal target for sensitivity demonstration but atm there are no emission regions visible from my site.

Integration time 24x600s with GSO 8" F5 and Skywatcher NEQ6. I did the processing with PI (still learning ). I would like to learn how to get the deep space noise better under control. Any hints are welcome!

best regards Matthias

Thanks, i also can`t wait to do my first real narrow band imaging with this camera

I think that this is an excellent test of sensitivity and shows that you have as much outer halo as is generally ever seen. A few have gone deeper but not many and not by much. Well done indeed.

I don't think I've ever seen such a deep image using a dslr. Stunning work.

Excellent. I have the same camera in Mono too but no chance to test it yet.

Superb image!

Where do you get cameras monomodded?

Mostly it is a DIY job, not recommended, or you find one from some one who has done it successfully. I have converted a Canon 350D to Mono myself that is why I would not recommend it unless you have a few cameras that you do not mind putting in the bin. I got the 5100 from one of the members here on SGL, Herra. I sent him a private message asking if he wanted to sell it and he did as he was saving for another project . There are a few firms that do it professionally but TBH with the asking price one is better off saving for a proper CCD as most of them are way too expensive, heavy and bulky and at the end they are DSLRs without support. I just wanted to have one as I already have a 314L and 383L mono,  please do not ask why.

Hello,

after killing one D5100 sensor in my modification attempt, i also got my modified sensor from Herra. Regarding the total cost my D5100  was still alot cheaper then a CCD with KAF8300 sensor. To put this into perspective: For one KAF 8300 CCD you can roughly buy 10 used Nikon D5100. I do not own a dedicated CCD and eventually i will get one for sure, but i would say that mono DSLR`s are a cheap entry to mono imaging.

That's an amazing image   Better than anything I have managed as yet with a 460EX or 314L+ mono CCD camera.  I'll be having another go as soon as we get some clear night skies   I think this is my favourite galaxy

Wow! that is deep. Reminds me of a mono version of Olly P's M51.

[frostynixon]

@Gina: M51 is probably also my favourite galaxy because there is some "action" going on, although M64 is not too far behind in popularity

I want to add some color to this image soon. Do the RGB channels usually come from broadband red,blue,green filters or are they constructed of narrowband Halpha, OIII and SII data?

I guess the answer depends on my local light pollution right?
