Amateur Spectroscopy - Part III: Equipment & Acquisition

Merci pour le conseil. I need to get back to theory before I get some hardware, and since I have the Astronmical Spectroscopy for Amateurs from Ken Harrison, I can do that.

That's a really interesting use of Nina in multiple instances. Thanks for sharing this.

Amazing videos, Julien! I can't wait for the next part(s). CS!

Very cool. Some legit science going on here :) I had a rough idea of how spectra was captured.. nice seeing it in action. CS!

Exceptional workflow and video description!!! I want to try to get something similar going for my Alpy 600. It'll take time but you identified all of the important pieces. Thanks!!!

thank you for these videos

Nice! Was missing the analysis of the planetary nebula at the end, but still, cool!

Wow!!! 👏👏👏👏👏

very interesting

Fantastic video, so clear and fun to watch! I really hope you will make a video on processing and calibration. I wonder how we can use our AP tools (pixinsight, siril) to overcome some of our spectro hardware limitations (aperture).

Brilliant videos thank you. I have a Star Analyzer, but I am looking into acquiring StarEx. I am still thinking if I should buy a 3D printer or off the shelf kit. I own a couple of OSCs one is a TEC cooled APS-C would it be suitable for recording spectra? Mono camera I have is very basic and not suitable for serious spectroscopy work I guess. I'll be on lookout for the next video(s), will be very interesting to see how you process the spectra.

Very nice video! I did not know such interesting results could be within the reach of amateur astronomers! I am very tempted to try. Is the use of a monochrome camera mandatory? I do own a cooled color camera (ASI 2600MC pro).

Enjoyed the 3 part series and was wondering if you will be doing one on how to use the Spectrograph software to calibrate and then see the results? Thanks

I was excited by the potential right up to the point you started talking about mini pcs and multiple instances of Nina and phd2. I use an Asiair for all my image capture routines - am I still able to use a star ex or do I need to look elsewhere? Thanks

Nice video of your workflow. I have just build a Lowspec and have a similar worflow with 3 instances of NINA. Do you also have a flat lamp or so you use the continuum of the reference star for that? And do you leave the Neon bulb on all the time?

I think it would be more fun with color spectra and also could confirm frequency of each line. I'm thinking the grating must be a mirror grating- would love to know more about that.

Nice video. .I was under the impression the Neon spectral lines only go as high as 5401A. How is that you are able to get multiple Neon lines greater than the Ha 4861? I have been searching for Argon bulbs in order to get spectra reference lines in that range.

I ended up buying Ken Harrisons slit wheel, made by Ovio for the LowSpec but have changed my mind and now want to make a StarEx. Would the StarEx benefit by having a variable slit as I'm sure I could mod the StarEx to accept it ?

Great video. Did you get your optics from Shelyak in France, or is there a seller in the US? You use an AstroTech Scope I believe; do you know if an Esprit 100 ED APO Triplet from SkyWatcher would work as well? Thank you for the great content.

Thank you very much for showing us this very interesting way to perform amateur spectrography ❤ To be honest I didn’t hear anything before about Christian’s project and in general it’s relatively calm here in Germany in the amateur astronomy community what spectrography concerns. I have one question: would it be possible to create spectrographic pictures of dim objects like Christian does it with the Sol’ex and our sun. It should be possible either with bigger objects or scopes that provide enough magnification. Of course the process would be much slower and instead of recording a video a series of long exposures should be taken with a tiny move of the scope in between.
