One day soon(tm) ...

In the same forum someone was ranting exactly over that learning curve and expressed his thoughts about vts with less reserve than i did :-) He said that he tried several hours and didn't even get behind a certain process in the workflow. Then he got an answer from someone who claimed to do astroimaging since years and just scrapped the work of 160 (sic!) hours on a single image just to start all over again.

Conclusion: keep smiling :D, things could be worse :cool:.

 

And remember that it's just a hobby - if it starts to get on your nerves, just put it aside for a while :) One year is not much time. Number of suvcessful imaging sessions I had this winter: 0. And now the evenings are not really dark anymore.. (@>60 deg latitude) Maybe next year :D

Pixinsight has technical essays on their website, if you want more under the bonnet knowledge about astrophoto processing.

I hope you have a good tracking - chasing Jupiter at >300x magnification is not funny...

Also, I question the final f/D. It may very well be that you can only see part of Jupiter.

scratch that, dem planets are tiny !

Yeah. Thanks for the words. I had a few days in December and January, adjusting the equipment and one night for orion nebula. Yesterday for example i had a steel blue sky, but the wind was blowing too strong and gusty and it carried a spray over the ridge behind my place.

PixInsight is indeed what i am trying to get into with the help of the book "Inside Pixinsight". Can recommend it.

Btw. I remember the midnight dusk in june when i was on the baltic sea. Am at 28 north now; not that much difference in length of day night :-)

But you see I get spoiled at midwinter, when I can set up and start imaging in the afternoon and go to bed early ;')

Created a map, too!

THAT IS WHAT I HAD TO CHASE ! Just to align out the finder ! No motors ! For the sake of CCDs ! Good god ! Nice !

How "spoiled" were you when trying to take that ? :sticktongue:

EDIT (and sorry for sliight digging) :

Image processing is driving me nuts. ... ... As soon as as you cook your own soup i mean use your own data nothing works as it did in the vt. ...

Frustrated after several days i visited a forum ... ... posted my question and get a wavy answer like "did you check the "Lightness mask" box ?". *sigh* "Thanks for the reply, but, yes, i did ... ?"

Vts are just a waste of time and bandwidth. I just read that someone has written a book about astro imaging software. I hope i find the answers that i am looking for there. [/rant]

I suggest you to meet up someone who understands the program (and, in case it's not the same but does the same work, probably the program he/she may be using, as long as it's doable). TBH this is how most people today learn such programs anyway - unless one had experience with a very similar looking / tooling program(es), you'd have a hard time trying to even get through the whole thing.

If you can't, well... maybe waiting for the right time ?

AFAIK the controller that I had installed for some CCD experience back then actually also contains the tooling to process the images. I've moved to a new laptop and I didn't carried it over...

I am already the one-eyed among the blind :-) If i want more i'd have to pay for a course.

The book i mentioned (Inside PixInsight) is actually very good. It is absolutely feasible for a half-educated newcomer like me and explains processes and steps with the software very well. So, if people are willing to invest a little something in astroimage processing software this is the right way and it's, compared to Photoshop, inexpensive. Also, compared to the freeware Fitswork (which has a good reputation !), PixInsight is far more sophisticated.

And (the reason why i will buy it as soon as the trial license has expired) it's available for Linux (also poorly programmed, needs root rights to install, but i have an installation for these unruly cases ;-)) and you can really download and install it and disconnect from the bloody internet while working ! Wow ! /sarcasm

Yay ! Good weather, where are you ?

:-)

What I meant was meeting with someone from a local astronomy club (preferentially those into astrophotography) or better someone into astrophotography/astroimaging (academic or professional but non-academic) or even much better someone who works in an observatory and/or academically studies/studied astronomy (esp. in observation). The last ones were where most of my knowledge came from - I had enough exposure to know the lengthy measures it takes, least in the "old" days, how things were done (and some trials myself). It's probably rare to be able to do that though !

I'm quite sure if you go on a star party in an observatory site (or even if not) someone there will just know all of it.

To be clear, I'm not active on the subject in any way :wink:

But if books works enough for you, great ! Have a good time now, may patience be with you for the weather !

Here's my attempt to capture the Big J from way back in 2012.

09qWMhC.jpg

If you squint and follow a line from the planet to the lower left corner you might see two dots. Those are Io (the one closer to the planet) and Ganimede (near the corner).

When I set out for some night photography, all I had with me was two DSLRs, a bag of lenses and a tripod. I took my motorcycle and crossed a local mountain, so that I can at least put the mountain between myself and all the light pollution from the city.

So, there I am, in the middle of nowhere, halfway down the wrong side of a mountain (no big towns anywhere near), in pitch black night, on a road that sees little traffic even during the day, clicking my long exposures when suddenly a pair of xenon lights turn around a corner and mess up my shot. Ah well, memory card space is cheap :). But, the car stops just by my side and a bunch of guys start pouring out. "Whazzup!" "Hey" "What ya doing" "Shooting stars" "Did we mess up your shot?" "No biggie"...

Long story short, these guys start unpacking this huge telescope out of the trunk of the car. Great! More small talk and they seem cool enough so I kind of attach myself to their eyepeice. They have some trouble with polar alignment, but eventually they turn the scope to Jupiter. Of course, they don't have the adapters to mount my camera on the scope, so I take the picture above afocally, handheld, hence the shake. Unfortunately the camera didn't catch Callisto that was just outside of the frame.
