NGC6888 in c/astrophotography@lemmy.world
[–] bistdunarrisch@lemmy.world 2 points 2 weeks ago

Sadly my lens has not perfect back focus, since I‘m using a system camera there is nothing I can change about that. The effect is a little bit compensated with using BlurXTerminator.

The image is cropped a quite a bit, the aspect ratio is still 4:3 however.

Thank you for your work.

As far as I understand it one of the big advantages is that every viewer simultaneously provides its download data for others to stream (peering). With this approach server capacity can be reduced but I wonder how well this works (If I even understood it correctly).

With this system could it be possible to host videos on an own server without having to pay huge sever costs?

Also what is a nice website to search through all videos, similar to the front page of YouTube?

I tested Procreate for iPad. I have no prior experience in drawing other than art lessons in school, so I was plesently suprised on how well the image turned out. Of course it was inspired by Bob Ross.

Heart and Soul nebula (europe.pub)
 

On our journey to shot the best images we can with our non ideal setup we collected more data on the heart nebula. Main problem with our setup is the distance of the sensor which is not perfect and results in bad star shapes in the corners. Stepping down to 2.8 and using BXT helps a lot. Combined with old data we gathered a total exposure time of 14 hours.

Editing:

  • stacked, remove green noise, BGE in Siril
  • BXT, SXT in Pixinsight
  • streched with GHS in Siril
  • NXT, colouring, contrast, recombining stars in PS

NGC 7293 - Helix Nebula (europe.pub)
 

This is a first test to shoot NGC 7293 with a 135mm lens. Sadly we could only gather 15 min exposure time as the time frame for shooting this nebula is super short and we had a lot of clouds. Hopefully we have better conditions next year. But this test makes us hopeful to get a decent image with our equipment.

PCB etched with toner transfer method (europe.pub)
 

This was my first try developing my own pcb with the toner transfer method. I did this project many years back but it works perfectly to this day.

It filters an audio signal and drives led strips so they pulsate to the beat of a song.

M31 Andromeda (europe.pub)
 

We really struggled to combine RGB with Ha. For our first try at continuum subtraction however we are very pleased.

Equipment:

  • Samyang 135mm f2.0 lens
  • Fuji X-T5 (unmodified)
  • Star Adventurer 2i
  • STC duo narrowband filter

Images:

  • 288x 60s RGB
  • 592x 60s narrowband

Processing:

  • stacked in Siril
  • remove green noise
  • background extraction
  • star removal on both rgb and Ha
  • continuum subtraction with Pixelmath in Siril
  • adding Ha to RGB with Pixelmath
  • BlurXTerminator
  • NoiseXTerminator (0.5)
  • GHST
  • final editing and recomposition in Photoshop

Camera lens mount for astrophotography (europe.pub)
submitted 11 months ago* (last edited 11 months ago) by bistdunarrisch@lemmy.world to c/3dprinting@lemmy.world

I found this design and it fitted my need perfectly. It is a mount for a very popular camera lens used in astrophotography. It not only functions as a weight relief for the camera but also allows to rotate the field of view. Moreover it is possible to focus the lens with the installation of a stepper motor, which will be the next step.

The single parts are screwed together with the help of threaded heat inserts. Just to make sure they are also glued together with epoxy, as the mount really needs to hold up. The screws are locked with Loctite.
