I could try and better that but I would rather just look at it, lovely.

First shot of the moon using the Skywatcher 120mm x 1000mm fl Black Diamond refractor telescope and the ZWO ASI1600MM camera

All my previous moon imaging was with a DSLR camera and telephoto lens

Recent lunar pic:

Along the centerline is Rima Hyginus (with crater Hyginus), above the rima is Mare Vaporum (the lava flows have only a few hundred meters elevation variation), below the rima are the craters Hyginus A, Triesnecker, and at the base of the 600m high eastern ridge of Murchison, Chladni (which is relevant since we just covered sound in Physics I)

HI recently I made some scope pictures of Arcturus and Spica.(its quite fuzzy due to long exp. time) but I think that colour difference is remarkable (Arcturus surf temp. cca 4300 K, Spica cca 24000 K).

Tour of the Moon in 4K (NASA Goddard)
Take a virtual tour of the Moon in all-new 4K resolution, thanks to data provided by NASA's Lunar Reconnaissance Orbiter spacecraft . As the visualization moves around the near side, far side, north and south poles, we highlight interesting features, sites, and information gathered on the lunar terrain.

very cool

The clouds parted for 2 days, and while the moon is annoyingly bright, I was able to get a nice start on M101. The first image includes some surrounding galaxies, while the second is a close-up. Images acquired with a 400/2.8 lens, 15 second exposures (yay, declination!), ISO 500.

I can still do a good bit of denoising and improve the flat field correction, but what I really need is less moonlight.

Another good night of viewing- no moon this time. Up to about 2 hours total integration time.

Hi I attach moon colour enhanced image (registax+photoshop). Are you experienced with this process ? O would like to know if is true that you can visualise true colour of object (for example rock of moon and so on) which can not see by naked eye...

Have nice astro experiences

awesome effort

just remember tho, the moon isn't really that colourful ... it's basically all grey

up this thread a few posts back...
Post #302 ... my moon pic and post #304, Andy's pic. show the natural colour of the moon

So in summary ... great detail in your pic., just go easy on the colouring Dave

 

[bruha]

Hi thank for your post. Ya I noticed as well that moon is basically grey (since some green and blue rare rock are present as I read). It is as I read quite lot instruction on web how to enhance image moon colour and just wandering if it is only " game" or has it some relevant (real) matter.
You have absolutely beatiful and detailed images. -congratulation

thankyou

you didn't comment on what telescope, camera etc you used to take that image ?

There is real science behind colorimetric imaging of the moon, primarily in connection with minerology:

Enhancing the color (increasing the saturation) is a fairly standard approach:

The region around Aristarchus is especially colorful:

Hi thank you very much for answer and links- I am interested about this theme so I will study this. My picture was made by hyperion eyepiece 8 mm on Newton 100 x 600 mm and sony compact camera objective just attached through T-ring . But now I got Nikon DS 200 body with bajonet .. so I will hope that made some improvement.

 

[bruha]

Hi

 

[bruha]

Hi I attach my last attempt colour saturated moon image by photoshop- jpg format,( but when I saved as jpg from photoshop it lost almost 50% of saturation- -I do not why and original photoshop is too large-cca 120 MB!). If you could estimate if it could be real colour ...?

M13 is visible here this time of year:

This was digitally zoomed to mimic a 2400mm focal length (stacking w/ 3X dithering), total integration time 24 minutes @ f/5.6. This cluster has long been difficult (for me) to obtain a decent image: @davenn checked through my work a while ago, and it really helped. Every year I learn improved ways to acquire, stack, denoise, and convert to a 8-bit/channel final image. It's also a good warm-up for imaging the dense starfields in Cygnus in another month or so.

M13 is visible here this time of year:

M13 doesn't get above the horizon for me in the southern hemisphere, instead we have the majestic Omega Centauri globular cluster

This is the first deep space object I have imaged through the Skywatcher scope ( the same setup as in post #303 up this page)
Skywatcher 120mm x 1000mm focal length, Black Diamond, refractor telescope and the ZWO ASI1600MM camera
a 2 sec exposure @ F8.3

Now the Ring Nebula (M57) is viewable from my backyard; here's a full frame (800mm) image of the region, combining images taken this year and last year:

Note the flat-field correction gets worse at the periphery, where image fields don't overlap anymore. Even so, the correction is pretty good over the entire field. Here's a 1:1 crop of the nebula and surrounding region:

IC 1296 is (barely) visible. Now what I've learned imaging Hercules is paying off: here's a 3X version of the nebula, clearly showing the 14m white dwarf at the center:

and a cluster nearly shows that my image can clearly distinguish stars 4.0 arcsec apart (the short vertical group, distance data from Aladin)

4.0 arcsec corresponds to a diffraction-limited aperture of 3.1 cm (500 nm wavelength). If we let the 'limit' go down to 3 arcsec (since the stars are clearly separated), the aperture diameter is given as 4.2 cm. Since my lens has an aperture of 14 cm, the impact of poor seeing is quite obvious.

great shots, Andy

 

[bruha]

Hi, really great shots!
I attach my attempt of Jupiter, but it is not satisfying.. First is made by compact Sony just pressed to hyperion ocular 8 mm (probably one moon is visible as well)
and second is made by Nikon D 200 body attached by bayonet to hyperion (it is quite dissapointment- I set ISO to 1600 and exp. time to 1/4 sec.(shorter time show nothing on display) .. If somebody have some advice for improving of Jupiter image I will appreciate,,,

These photos taken by an astronaut at the ISS are pretty amazing

ohhh yes...

there is a youtube channel that has streaming video from the ISS ( it is not always live, due to various reasons)

I absolutely love this music and video

Final results (for this year) of the Ring nebula; 3.5 hours total integration time at ISO 1600.

Whole field of view:

1:1 crop (no dithering):

In related news, I have the opportunity to buy myself a present- I've had my eye on a 105/1.4 lens to replace my 85/1.4 that I lost due to migrating from a Sony camera to a Nikon camera two years ago. Hopefully I'll get it in time for imaging Cygnus this year. Stay tuned!

Hi I attach my recent attempt of Saturn images (by mobile camera on eyepiece hyperion). I was trying this method beacouse I can not catch it by Nikon body camera attached by bayonet. If somebody has some advice and experience of Saturn photo I would appreciated it..
Thanks and have nice days
