At last night I tried to get some color. But my color camera is not so sensitive, like my monochrome. Anyway here are the pictures. I used a Baader moon and skyglow filter, because of the light pollution. The two birds are Swan and Eagle, on last picture is Lagoon.

Another clear night on Friday (although round about 2am it got really really cold) and thought i’d Snap the Dumbbell Nebula with my 300p dob with goto. Details stretched with Lightroom mobile (btw if you don’t have it Lightroom, get it!!!)

 

 

Very nice picture! I try also tonight the M27, I just pray for clear sky. I had an effort with my 8" SCT at last sunday, with my Huawei P10 monochrome, but I want to see the colors of this object now.

From the 15th May (at 21:55 GMT), stars below Libra.
Spica middle top, y-Hydra middle bottom, and Kraz (from Corvus) bottom left.
Stack of 9 shots... hand held.
Colours are "interesting" from the Bayer interpolation and levels boosting.
Two images: full frame scaled to 1800 pix wide, and a 1to1 pixel crop from the centre of the original frame (63 Virgo, 61 Virgo, and HIP 65183 making a triangle in the center); plus full frame 16bpc TIFF file.
Processed in Photoshop.
Each pixel is c. 12 arc-seconds. Stars visable down to magnitude 10.
Nikon D800 with Nikkor 85mm f/2.0 at f/2.8, 9 x 2.5 seconds, ISO 800. IDAS D1.

Maybe because of my poor english I don't understand that. So, you take 2,5 second expositions only with hand, without stativ about the stars and they does not move?

You can see more stars in the mono one. Have you tried using it as a luminance layer over the colour version?

You mean, to stack them somehow? I didn't try that.

The different of Huawei P10 color and monochrome camera. Ring - nebula, ISO 3200, 10 sec exposition, Celestron Nexstar 8", 25 mm eyepiece. 

This is my first post when I afraid, my english is not enough to explane something, huh, so: I just tried to use the "light painting" - mode on my Huawei P10, but not to see  that, how the stars make lines on the sky. I used this function with my Celestron 8" SCT on alt-az mount, with following. Its interesting, because it makes pictures in every 3 second and stack them in real time! Interesting to see that, how the stars comes up from the dark. I made a screen video about that, how its going, enjoy! Video 1:Alpha Lyrae, video 2:  Ring nebula

Afocal DSO shots, with a cellphone on an alt/az. I can hear the screams of "you can't do that" from here.  

And alt-az mount... Yes, I heared that, its impossible. This is exactly the reason,  why I do it ?

At last november I bought a G3 Orion deepsky cam, but in the winter I didnt use that. Because of the cold I dont like to take picturs with the cam + laptop combination. Anyway, I took a picture about the center on Orion nebula, the Trapesium. Its much better, as my smartphone pictures, but with the cam I have very small field, because of my 2000 mm focal lenght.

Hi All! Finally I tried to stack few pictures in DSS, only to get some experience about that. My object is Messier 4, I took 5 x 5sec pic in raw mode with my Huawei P10, 25 mm eyepiece (80x magnification) with my Celestron Nexstar 8" SCT. On my laptop it looks great, it shows the young blue and the older red stars. Interesting, but on my phone its only hard yellow, all the stars in the cluster. 

Hi All! That was an unbelivable nice night here. My Celesteon Nexstar 8" SE with alt-az mount was ready to watch the sky. I took again pics, over 25mm eyepiece with my Huawei P10 smartphone, in monochrome mode. ISO 1000, 15 sec exposition pro object. Swan-nebula, Lagun-nebula, Trifid - nebula. There is no edit on the pictures, only cut and rotate with Lightroom app.

It is true that over time the images will rotate, but so long as the field rotation isn't significantly visible on a single frame (i.e. each exposure duration is short enough), DSS will automatically de-rotate them and align them. To my mind the slight problem is that I guess the images that you get from your 'phone are jpegs, which is less than ideal, but it will still work. The issue is that you will still need to significantly enhance the contrast of, or 'stretch', your stacked image, and the 8-bit jpegs will not take kindly to that process. Still, you've done it with the image above, so it should be better with a stacked image. Give it a try, that's the only way to find out! It's a while since I used DSS, but I guess start off with the default settings. Have a look at the User Manual on the DSS website, or alternatively there are a number of on-line help videos and tutorials. It's not a difficult piece of software to use.

My phone can take picture in Raw too, but only in color mode. I took almost all my pictures in monochrome mode, because it has 20Mp. About the M104 I took pics in Raw, here is one of them, sure, I see the difference:

That's come out rather well for just a single frame. You could try taking a lot more and stacking them in an external application.

Thanks for help, but can you help me please,  how is it going? I have alt-az mount, so if I take more pics, because of the rotation they are not the same field. I have DSS on my computer, but I don't know the best settings to stack these pictures. 

Very cold outside o.O Not important, I have some new pic and I want to show the M51, how my Huawei P10 sees that over Nexstar 8" SE with 25mm eyepiece. ISO 3200, 30sec exposure in monochrome mode, cut and contrast with Lightroom mobile app.

Hello smisy and welcome to the hobby

For a beginner IMO you actually happen to start with one the most difficult configurations: long focal, high focal ratio, ridiculously small sensor, and ocular projection which magnifies again the already long focal... and of couse Alt-Az mount. So getting any images is an achievement it itself, and yours are quite decent.

Good luck and skies !

PS: your M42 looks mirrored left-right to me :-P

Thanks the welcome! I have some problem, but I hope, I'll find a way to fix them. My smartphone works only with my 25mm eyepiece. In the others (15mm and 8—24mm baader hyperion zoom) there is a black field in the center of eyepiece. I tried to pull up and push down the phone, to change the focal lenght, but its not working :/

PS: Maybe because I live on the other side of Earth?

Welcome.

Those are great captures.

Have you seen this?

Thanks the tipp! Very friendly! 

Hi all, sorry for my basic english! I found this topic at last may, when I started to interesting about astronomy. I bought later a Celestron nexstar 8" with alt-az mount and in this year I started to take some pics about the beautifull objects on the sky. Of course at first with my mobile phone, I bought a little bit expensive phone adapter to fix that on the okular,but it works very well. I want to share my first pics now, to show that, its not impossible to make pics with mobile phone, about dso-s too.
