    As a young kid, I always wondered what was out there among the stars. You're most welcome to join my quest to capture the night sky!

  1. Aha, OK. Thanks for sharing your experiences. I assumed that most people like myself own a DSLR...and use that as a first step into astrophotography. But that might not always be the case...and it is true that my ZWO 1600 MM pro produces far higher quality images as compared to my DSLR..and a CCD is of course supernice in terms of quality. But I don't feel that time was wasted...I first had a lot to learn about polar aligning, guiding and capturing. But I can imagine that some have other experiences. Something to consider in my future videos. Cheers!
  2. Hi folks, I thought it would be fun to make a video on my recent attempt to capture the North America Nebula in Narrowband: https://youtu.be/MXMTuGdF9Sw Cheers and clear skies! Wido.
  3. Hehehe. Depends on his/her socio-economic status and if you like him/her....lol
  4. Thanks for the update Goran. You are definitely correct about the redshift. I was confused because I saw some info on the Hubble Space Telescope where they mentioned this. It only applies to early galaxies. For CMOS, I always thought that those sensors were heavier on read noise, hence the dark frames needed to compensate for this. But if this is not accurate I'm all ears. Thanks for watching the video!
  5. Thanks Carole! I'm still thinking about migrating to spain / greece to do astrophotography...especially with the weather we have been getting in the past month :-). I captured this early september, after that, only rain, ah well, we're used to it I guess.
  6. Hi folks, My second attempt to capture NGC 7000 using the Hubble Palette from my Bortle 8 class city Utrecht in the Netherlands. Some details: Imaging telescope: TS photoline 80mm apo Imaging camera:ZWO ASI 1600MM-Cool pro Mount:Celestron Advanced VX Guiding telescope or lens:Orion Mini 50mm Guide Scope Guiding camera:Zwo ASI120MC Focal reducer:TS2 Flattener Software: Deep Sky Stacker and Photoshop CC Filters: ZWO S-II ZWO 7nm SII, ZWO O-III 7nm, ZWO H-alpha 7 nm Images: ZWO S-II ZWO 7nm SII: 45x300" bin 1x1 ZWO H-alpha 7 nm: 68x300" bin 1x1 ZWO O-III 7nm: 65x300" bin 1x1 all cooled at -25C, 5 minutes exposure. Compensated with flats, but had trouble adding dark frames for some reason so I left those out... Total integration time: 15.8 hours. During a - close to - full mone (93%). Let me know what you think (honest opinions are appreciated :-)! Cheers and clear skies, Wido.
  7. I love the way you post process...still got a lot to learn. What techniques / software are you using? Any tips? thanks
  8. Hi folks, From time to time get asked what kind of astrophotography camera should I buy on the (social) media accounts where i upload my images. There are many technical discussions (which is helpful of course) but in my opinion it often also depends on the interests of the person itself en his/her skill level... For example, I wouldn't recommend a CCD mono camera >$3K to a person who is starting his/her hobby :-). Anyhow, I attempted to capture that in a video and put it on my personal YouTube channel, here's the link: https://youtu.be/HhIAEnVMzHU Feedback is highly appreciated, and I know I have a (Dutch) accent...being a non native speaker... I'll keep at it and hopefully it will improve over time :-). Clear skies, Wido.
  9. I folks, As nights are cloudy here in the Netherlands, I decided to make a video showing my different steps on how I polar align my telescope using sharpcap. You can find it here: I'm also wondering if this is the best way, or is there other software that is superior to this? I've been hearing good things about EKOS and the ASIAIR? Cheers, Wido.
  10. Thanks @carastro @upahill, I've recently been to the south of the Peloponnesos (Greece). With my family so no astrophotography gear, only my DSLR and a kitlens. It was so beautiful to see the milkyway and jupiter (close to the milkyway) during some moonless nights. Truly amazing. We don't get that in Utrecht (although I do like living in the city). Some day I'll buy a tiny house in a green zone and put all of my astrography equipment there :-).
  11. Hi there, I'm pretty much bound to light polluted skies in Utrecht (the Netherlands). So I made a video on how to perform astrophotography in the city using narrowband filters. In this case, I'm using ZWO 7nm narrowband filters (Ha, Sii, Oiii) to image IC1396 - The Elephant Trunck Nebula. I also discuss differences between imaging with broadband and narrowband filters and how narrowband can rescue astrophotographers who are dealing with a lot of light pollution like me. You can find the video here, hope you find it useful: https://youtu.be/0_yjtMllNK4 Clear skies!
  12. Hi there, I've collected rgb (narrowband) images across multiple sessions with some months in between. I've already created a stacked image for each session. Would it be wise to combine the already stacked image with a second stacked image, or should I just use the individual images, put them into multiple groups, to create a new stacked image? Happy to hear your thoughts on this. Wido.
  13. Asi1600mm pro Zwo ha, oiii, sii 2019 narrowband filters Teleskop service photoline 80mm refractor Thanks!
  14. thanks! added a bit more clarity
  15. Hifolks, Here's my take on IC1396, let me know what you think. In total 7.5 hours exposure time using narrowband Ha, Sii, Oiii. Post processing in photoshop and lightroom. Thanks for watching, clear skies!
