Zooming in you can see the honeycomb effect. Pretty cool.

Hi!

Finally clear sky again, so I was outside with the 8 inch Skywatcher Dobsonian and my OVNI-B.
Here are a few quick snapshots of the most beautiful nebulae in the constellation Cygnus that I was able to see with this combination and a 12nm H-alpha filter.

The photos are livestacks of 10 images of 0.3 seconds each with my ZWO ASI 178 MC.

1. North American Nebula

2. Crescent Nebula

3. Western Cirrus Nebula

4. Eastern Cirrus Nebula

5. C1318b Nebel (I don't know if it has another name)



CS,
Mario

Mario -- the photos look great. 

[Jeff Morgan]

Nice images!

 

It looks like an 8" aperture is almost enough to resolve the "?" feature in the Cresent Nebula. The 180mm Epsilon could not do it, and it is easy in my 16". Maybe a 10" could do it?

 

Something that really caught my eye was the apparent dark nebula near the Eastern Veil. I don't have an image that goes that far west. (I need more Veil images!)

 

Sky Safari shows no dark nebula there. If I can remember my Astrobin password I'll check those images. Could be just one of those random things.

Pay attention to: 

"photos are livestacks of 10 images of 0.3 seconds each with my ZWO ASI 178 MC"

 

This is already starting processing that approximate NV to EAA and this may not match what you see with the eye in NV in various telescopes.

Livestacking with just 10 photos only makes up for scintillation in my opinion. The images are very close to what I can see visually with my night vision device.

 

In contrast, a single photo would be significantly worse than what I can see visually through the eyepiece.

Thus, the photos match my visual impression very well.

Another case of Live and Learn. But hey, those were the early days of NV phonetography.

 

These days, I would drop the focal reducer and go either prime or prime + barlow for globulars.

Many shots with my OVNI-B from last night:

 

- Without telescopes (only the night vision device in hand):

- 7nm H-Alpha filter
- Livestacks from 30 seconds with ZWO ASI 178 MC

 

 

1. Nebulas in the constellation Swan

2. Nebulas left of the constellation Swan

3. Combination of the two images

4. The great nebula Sh2-27 in the constellation Ophiuchus

 

Further images taken with the night vision device through the small 60/330 Apo:
 

- TS 60/330
- Afocal with TeleVue Plössl 67mm + 0.7x Reducer
- 7nm H-Alpha filter
- Livestacks from 30 seconds with ZWO ASI 178 MC
 

With the 67mm Plössl and the reducer I can bring the small apo to a field of over 7°, but this effectively means f/1.55. With this, the stars at the edge suffers considerably, nevertheless the image is bright with it and the field of view is large, which was the goal here.
OVNI-B + Cam + afocal is a little bit crazy ...

1. Cirrus nebula

2. Dumbbell nebula + Sh2-86 (the dumbbell nebula is the tiny very bright thing in the lower left)

3. Crescent nebula and surroundings

4. Tulip nebula and surroundings

5. North american nebula

6. Nebula Sh2-119 in the constellation Swan

7. Gamma cygni complex

8. Trifid + Lagoon Nebula

9. Sh2-54 + Eagle Nebula + Omega Nebula

10. Sh2-41 nebula

11. Combination of Sh2-54, Omeganebel, Eagle Nebula and Sh2-41

In those early days I was still feeling my way around cell phone photography. One thing was clear, prime focus with the Tak Epsilon was almost magic. The cell phone image had nice tight images right to the edge of field, but still did not do the visual image justice.

 

In all my years of astronomy, never thought that 19x images could be so engrossing. I miss that scope. Maybe I buy another

One of the things about a fixed 40 degree AFOV - even a wide-field instrument like the Epsilon can't frame the bigger vistas. It manages about 2.2 degrees with NV.

The Question Mark feature is easily visible in this aperture, whereas my 7" Epsilon only hinted at it.

Hey guys here is a photo from the second outing I've had with my new night vision setup. I would like to thank everyone who has contributed to this thread because it has been extremely beneficial in helping me get up to speed in this incredible new field of imaging.

 

After testing four phones (Huawei P30&P40+Pixel 4XL), I found that the Samsung S21 Ultra really has the easiest user interface and best results.

Wow!

 

When I read "unguided" I was not expecting much - but you got an excellent result.

[jconroy]

Thanks Guys!

 

Here is M20 the Trifid Nebula. You can see at a 1 second exposure, there are star trails. :-/ With this setup I am at a focal length of 2,743mm with a 41x mag using the modified 51mm (67mm) Plossl.  Also, the 41mm Panoptic works really well too.

Hello there

Here are my very first images, with my Ovni M and a smartphone good enough to allow long exposures. A big thanks to Gavin who helps me out in chosing (and using) it

 

i had the phone for some time now, but the weather is awful here in brittany. Last night, i got out for a few minutes at midnight, before the clouds came back. You will recognize the Cygnus area and even the little Crescent neb, and the roof of my neighbour 

 

Ovni M at x1 with Astrodon 5nm and Chroma 3.5nm

It's been a long time since I visited this thread, so I just spent 2 hrs. going through it from page one!  It's good to see the proliferation of Phonetography, and the great results here.  Since January I have taken more than 400 images, although many of them were simply to test filters or hardware.  Last week I was checking my AT 100mm EDL refractor and took this image of M22 from my green zone observing site, 40 miles from home.   This image used the 4" scope with a 2x Barlow, Mod 3C in prime focus, ISO 50, 1s exposure averaged in NightCap for 10s, using my iPhone 12 ProMax, no post processing.  Several months ago I changed how I attach the phone to the NV ocular and like it a lot better than using a phone bracket.  I'll have to post about that soon.  

 

 

This image of the Rosette Sh2-275, with cluster NGC 2244, was taken last winter using a Nikon 300mm lens at f:2.8 with a rear mounted 7nm filter, iPhone 12 ProMax, 1s exp, averaged 25s in NightCap at ISO 160.  Post processing included a small reduction of exposure (light), cropping and reducing color saturation for more of a B&W appearance.  

 

 

This one of NGC 2024 the Flame, with B33 the Horsehead in IC434, was also taken with the Nikon 300mm but with a 7nm filter, iPhone 12 ProMax, 1s exp, averaged 20s in NightCap at ISO 250.  This image also has no post processing.  

 

 

IC 443 the Jellyfish, was taken with an 8" Newt (ES 208) using a .73x reducer and 7nm H-a filter, 1/4s exp, averaged 25s in NightCap at ISO 10,000 (the iPhone 12 ProMax in NightCap with manual control can now go up to ISO 32,000!!)

No post processing on this image other than cropping and a reduction of color saturation.

 

 

M31 Andromeda, taken with the ES 208 Newt with an MPCC, 1/5s exp, averaged 10s in NightCap at ISO 200.  This one was adjusted in iPhoto to slightly reduce the exposure (light) and slightly increase the contrast.

 

 

[GeezerGazer]

Two more of Sharpless catalogue objects: 

 

Sh2-108, -112, -115, and -117  taken with a Nikon 105 at f:2.8 using a 7nm H-a filter, 1s exp, averaged 20s in NightCap at ISO 500, taken with iPhone 12 ProMax; no post processing

 

 

These 14 Sharpless objects were also taken with the Nikon 105 @f:2.8 using a 7nm H-a filter, ISO 800, 1s exp, averaged 25s in NightCap using an iPhone 12 ProMax.  Post processed to reduce color saturation and then marked with each Sharpless designation.
