I've been less active lately in this hobby, but I've a few images done, others waiting in the pipeline to be processed.
This is a "crowded" area of our Milky Way galaxy, visible all summer from the northern hemisphere. The Cygnus constellation is home of many named and nameless nebulae.
Starting from the left (North), below the brightest star, Deneb, the Pelican and the North America Nebulae are very popular; going to right, just below the brightest star close to the center of the image, Sadr, lies the Gamma Cygni Nebula. A bit towards the top-right there's the Crescent Nebula and going forward top-right, there's the Tulip Nebula. Finally, at the bottom-right corner, the Veil Nebula, a super nova remnant.
All these are surrounded by shiny gaseous filaments or dusty patches blocking the light.
I started this during the pandemic lockdown. All of the data was captured from my hometown from a balcony brightly lit by a sodium street lamp, but the narrowband filters did their job well, blocking successfully the sodium emission.
A total of 23 hours is made of 2x3 panels composed in a larger mosaic, each panel consisting in about 1h of exposure for the red Hydrogen and 3h of exposure for the cyan Oxigen, all through a Sigma 105 macro stopped at F/4, ASI1600MMC with 6nm Astronomik filters.
I'm planning to shoot RGB data too and make an RGB/HOO composition.
Cheers and clear skies!

Have anyone tried to make a DIY version of hand controller for zwo eaf focuser? Or tried measuring what is the output of the controller?
I want to print a hand controller +battery case all in one but unfortunately do not have the controller to check what needs to be outputted thru connector. I assume it will be pretty basic like shortening contact but maybe someone has already checked
Thanks for looking!
Because of the current situation, I have, as many of you guys probably have too, spend a lot more time under the stars when possible.
It has literally been over a year since last I was out doing some astrophotography because of work.
So here is my second take after the long break, NGC 3344 (The Sliced Onion Galaxy).
Initially I thought it would be a lot fainter than it was, so it was basically a shot in the dark, of just trying to get back at doing this.
But the final image actually showed a lot more detail than I would've hoped for!
Spring lent a lot of clear night, but those seems to be gone already. I would've hoped for a few more hours to add some more luminance data to it, as I did have to push it quite a bit.
I am not too happy with the shape of the stars either. Guiding was not very stable through the night, even though balance and polar alignment seemed to be good. Might need to update my Celestron PEC data?
Any advice or feedback is very welcome! 🤩

Hi all, I’m looking to sell my ZWO ASI1600MM-Cool plus accessories as a bundle. I’ve had a great time with this camera, but now have a baby daughter that is leaving me zero time for astro imaging! So I’m parking the hobby for a few years… but I’ll be back!
A lot’s been written about how good this camera is so I won’t reiterate all that, except to say that I’ve had a lot of success coupling it to my ED-80 ‘scope and HEQ5 mount. I image from central Bristol and the light pollution is horrendous, but this camera and the narrowband filters bypass that problem rather neatly. Here are photos I’ve taken with the camera:
The core kit I have is basically this: https://www.firstlightoptics.com/zwo-cameras/zwo-asi1600mm-pro-usb-3-mono-camera-efw8-125-lrgb-filters-125-ha-sii-oiii-filters-bundle.html
Note the link is for the “Pro” version, which is slightly different to my one in two ways. One, the Pro has an in-built heater for the sensor. I bought one separately for mine, which of course I’ll include. (https://www.firstlightoptics.com/zwo-accessories/zwo-anti-dew-heater-strip-for-asi-cooled-cameras.html). Two, the Pro has a larger memory buffer, but I never found the lack of this to be an issue with my usage.
Also included is a slightly different version of this holder ring.
And an adapter so you can attach Nikon F lenses.
And this very useful cable!
I've taken plenty of photos so you can see exactly what you'd get. First, here's the back of the camera:
And the front, showing the sensor and heater:
This is one side of the Electronic Focus Wheel. All seven filters are mounted:
And the other side:
Here's the Nikon lens adapter:
And the camera holder:
These are the cables it comes with. On the left we have the Lynx Astro cable, with a dual-tip; one for the camera, the other for the heater. Then we have the EFW cable, and blue cable for camera to computer -- both of which are originals. The blue cable is annoyingly short, so I'll throw in a longer one too.
Here's the EFW box and included accessories:
And finally, the camera box and included accessories:
Approx. price breakdown if bought new:
Camera and filters bundle: £1716
Holder ring: £49
Nikon lens adapter: £45
Lynx Astro Silicone Power Cable: £19
I’m asking for £1300 including recorded delivery to the UK; or £1250 if you can collect from central Bristol. Payment via PayPal or bank transfer. If it doesn't sell after a few weeks then I'll consider offers or splitting the kit.
I bought my first telescope, SW 150pds about 6 months ago with the purpose of astroimaging "when i feel ready". So far ive used my Nikon D810 for that, and I'm now planning on taking the step buying my first AP camera.
My targets would be DSO's, and not planetary. I want a mono-camera, not color.
I want to get away with a very good camera to a reasonable price (wouldn't we all...) and in this regard I've been drooling on the ZWO ASI 1600MM Mono for some time. The price for it is in the upper part of my budget, but I'm willing to if its worth it. I've seen from other treads that sensor-size isn't everything, and dynamic range and gain and all is just as important, but i have trouble understanding it all 100% when it's all new to me, but in my experience i am a practical person who learns things much better and faster with the gear in my hand. So without getting to technical, and staying as objective as possible - please help me with;
1. Is this a good camera to go for?
2. It's sold with options of filters 1.25", 31mm or 36mm - Why these options, and what determines what i would choose?
3. Would you go for another camera in this price range, and why? - Or to rephrase it a bit; If you were in my shoes, which camera would you og for?
I'd appreciate any help:)
I might add, that i understand that with my lack of experience, buying a mono-camera with filters and all might seem premature, but for some strange reason. I enjoy these "way over my head"-projects and figuring out things as time goes - I just need some guiding in the right direction.
