Yes it is

Definitely best images yet.
Edit: I figured out how to post the 'video':

Ah, so an alt-az mount you have!

My non-motorized tripod has a gimbal mount, yes. My motorized tripod (astrophotography) is a Losmandy GM-8 German Equatorial mount. The only real trick is that the non-motorized tripod can be arranged to allow the lens to point directly toward zenith- there used to be a pic on the web, can't find it now.

My mistake. Looked a lot like frame rotation to me.

My ISS video does indeed have frame rotation! As the camera slews, the relative orientation between the camera and object rotates (the gimbal acts as an Az-El mount). The lens has a adjustment allowing rotation with respect to the tripod, but when ISS is moving there's no time to fiddle around with stuff like that.

You do realize that the ISS is constantly turning ? :smile:

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)... :smile: :frown:

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

Not too bad :smile:

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 ??

untitled12.JPG
untitled13.JPG


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 :wink:cheers

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.
 
  • #706
Hello, and thank you for comments :smile:, 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..:confused:) Thank you and lot of success :thumbup::thumbup:

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

Result of Markarian_1910s.tif (RGB)-3.jpg


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.

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-
M101-6h6m-1.jpg


M101-6h6m-2.jpg


M101-6h6m-3.jpg


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

Result of Leo_triplet-4h45m-1.jpg


Result of Leo_triplet-4h45m-2.jpg


Result of Leo_triplet-4h45m-3.jpg


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

M51-4h45m-1.jpg


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

milky_way-1.jpg
Milky_Way_2.jpg


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.

Again, as I said some posts back, cut down your exposure time so that the images don't get overexposed :smile:
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 :wink:
give your optics a good cleanDave

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. :confused:. but I must check camera as well
Have nice day :smile:

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

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 :smile:

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

thank you , I see... :thumbup:
(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 ) o_O

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...)
