Hi, here is my last Venus image from yesterday...original and saturated image -, I quess if this light spot on saturated image just below Venus could be some object (star)...

cut down the exposure time substantially. It's way over-exposed and blown out

 

[bruha]

Thank you, ok

 

[bruha]

 

[davenn]

Not too bad

couple of comments ...
1) I have noticed in several of your recent photos a black blob ... maybe you have a lump of dust
or something on one of the lenses that need cleaning off ??

2) not sure why you are getting all that colour in there ?
The Moon should be a relatively uniform grey ( shades of). It's not a bad thing as such,
it's just not a normal thing cheers
Dave

I kinda like the colors. The Moon as we wish it would be!

Another thing to try would be to use a red filter and post it (convert it) in black and white. Red really cuts down on atmospheric disturbances and the image will be much sharper.

 

[bruha]

Hello, and thank you for comments , yes I will check my all lenses..
Concerning image saturation, I just read some time ago, instruction for moon imaging and there was suggested some saturation as illustration of different rock type of moon... (but I am not of course well educated in this problematic..) Thank you and lot of success

A view of https://skyandtelescope.org/observing/yanking-markarians-chain/, in Virgo:

30 minutes exposure @ ISO 1250, 400/2.8 full-frame. There are about 40-50 galaxies visible, although maybe not in this highly downsampled image. What is notable is my (new) ability to perform flat-field correction over the entire image, not just the central 40% or so.

I'll probably be able to retrieve my external hard drive (w/ 3 TB of 'good enough' astro images for stacking) this week or next from my office. Something to do... I should be able to re-create the top half of this.

 

[Andy Resnick]

Some preliminary re-stacking results; I'm totally fanboy crushing on the new software.

Here's M101: 400mm DX format, 6h integration: full image, then some crops-

Next, the trio of galaxies in Leo- again, 400mm DX format; full image and then some crops, 4h 45m integration time-

And a 1:1 crop of M51, also 4h 45m integration time:

Lastly, some 1:4 downscaled crops of the Milky Way, taken at 105mm:

My images are getting close to print-worthy! The Virgo cluster panorama looks great as well but is too large to meaningfully post here. Next up on the re-stack schedule is M13, M3, and M53.

Hello, I attach 5 moon image from yesterday little processed (maybe some interesting)
Your galaxy images are amazing

Again, as I said some posts back, cut down your exposure time so that the images don't get overexposed
They are a good effort but will look so much better with some exposure adjustments

I see you still haven't found those black dust (or whatever) blobs on the sensor or lens
give your optics a good cleanDave

 

[bruha]

Hello and thank you form evaluation. These were made by bresser camera applied instead eyepiece. I have possibility just adjut contrast , brightnes and saturation... Black spots is probable problem of scope mirror. . but I must check camera as well
Have nice day

 

[bruha]

Hello, problem is on bresser camera...Nowadays is almost full moon unfortunately here in Czech rep. //

Hello, here is image of Venus from yesterday (by Bresser eyepiece camera) ...

Jupiter image is really amazing... (how this cloud cover is approx. thick?)

very good

The moon from Friday nite (8th May 2020)

some hours after full Moon

 

[bruha]

hello, thank you,,
your moon image is very impressive, it is somehow processed?

Have nice day

Just very lightly in Lightroom, a bit of contrast and a little sharpening.
That needs to be done as I always photograph in RAW to get the best data saving
It only gets converted to a .jpg to be able to post on forums etc

The Moon was quite low in the sky, so a bit of atmospheric distortion and colouring was present

[bruha]

thank you , I see...
(I mostly did some colour saturation as well .. somebody say it could be real colour discrimination of different rock types but I am not sure )

 

[chemisttree]

Venus tonight very low in the sky. Notice the atmospheric refraction. (it couldn't be my poor focusing or, gasp!, my refractor optics. no no no...)

very cool

Last night I did some quick and dirty astrophotography with mobile phone only.
I went to a city park with just my phone and a tripod and took some random shots .

I believe that is called "Mineral Processing".

 

[bruha]

Hi I attach next moon image, this one is by eyepiece Hyperion 5 mm mounted to Nikon body -but this camera is quite old and thus not very good.
... no any planet is observable in Czech rep. now (within reasonable time )

Lot of succes

 

[chemisttree]

... no any planet is observable in Czech rep. now (within reasonable time)

Same here in Texas!

You both need to get out of bed a bit earlier

Mars, Jupiter and Saturn are visible in the southern sky before dawn

 

[bruha]

Hi, yes I see, (for me problem as I like night quiet. and go to bed not before 1 )
Did you catch some images of these planets?

Yes, I posted on here a month or so back :)

The Moon tonight. 6/7/2020

Astrotech 80ED, Oberwerk BLEM tripod, Universal Astronomics Micro Star Deluxe mount, Televue 25mm Plossl with Celestron #93608 variable polarizer, iPhone 6 (afocal) in HDR mode.
This took about 5 minutes to set up, figure out and photo. I used Orion’s Steadypix Quick Smartphone Telescope Photo Adapter that I recently purchased from OPT for teleconferencing. Had to remove the rubber eyecup on the plossl eyepiece before attaching the Steadypix adapter. That adapter is a very good deal! The clamp is self centering and the adapter holds the iPhone (sans Otter case) very securely. Good setup for bright objects through the telescope.

 

[bruha]

Hello,
its look very good . Can I ask-is it this adapter fit to hyperion eyepiece as well?
Thank you

 

[DennisN]

I had fun last night. I was filming and taking photos the Moon through my cheap Chinese scope.
Afterwards when I unmounted my scope I noticed that a bright spot to the left of it had appeared.
Jupiter, I thought. So I quickly mounted my scope and got to see Jupiter with all four major moons visible (Europa, Io, Jupiter, Callisto and Ganymede).
I'm not kidding, I almost got tears in my eyes .
I ended up taking a lot more photos, and I will try to do a composite image of the Moon later, and see if I can make photo stacks of Jupiter with the moons. If so, I'll post them later in this thread.

In the meantime, here is a movie of the Moon last night with plenty of details filmed:
(some clouds appear towards the end obscuring it)

Probably not without a T-ring spacer. About 10mm should do it. It would likely fit hard, straight-sided eyepieces with sides about 1cm high near the top. It doesn’t fit Celestron X-Cel (old style) either.

But attaching it doesn’t mean it will work. When I attached my 7mm Nagler to it, the iPhone could only see about 10 degrees of the available 82 degrees my eye can see. Not sure that I understand why. Perhaps the light leaving the eyepiece diverges into an 82 degree cone and the iPhone’s camera can only capture a part of that?

 

[bruha]

Hi thank you.
I have still one eyepiece: Sky-Watcher SWA-58-3.2. mm Plossl. Do you think this one could fit..?

Thanks and lot of succes

Here's a couple of merged movie clips I filmed of Jupiter and the four large moons last night.
From left to right: Europa, Io, Jupiter, Callisto, Ganymede.
A bit noisy, but hey, they move!
(Too see it in 4K, click the gear at the right botttom in youtube and select quality: 4K)

The planet Jupiter with the four large moons (Telescope, 4K)
And I did a quick approximate calculation to get a feel for the distance to the planet:

Jupiter distance from Sun: 778 570 000 km
Earth distance from Sun: 149 598 023 km
Distance from Earth to Jupiter (ca): (778 570 000 - 149 598 023 ) = 628 971 977 km
Earth circumference: 40 075 km
628 971 977 / 40 075 = 15 695

So the distance to Jupiter is approximately equal to the distance traveled around the Earth 15 695 times. And this is PF, so if I got it wrong I expect to be corrected.
(yes, I know it also depends on where the planets are at the moment, but it is an approximation )EDIT:

Haha, I checked what "Semi-major axis" is, since it was those numbers I used. I thought it was (sort of) radius, but it is (sort of) diameter. So the distance from Earth to Jupiter ought to be about half of the value above, i.e. (628 971 977 km / 2) = 314 485 988 km.

Which yields (314 485 988 / 40 075) = 7 847, i.e. the distance to Jupiter is approximately equal to the distance traveled around the Earth 7 847 times.

(stricken parts were wrong, see edit below)

EDIT 2:

Haha, no I was correct the first time, but read wrong the second time.
Semi-major axis is radius (sort of).
