Thanks for the info, and good luck with your observatory!
Thanks for a good video!! Everything is so good to understand
Merci Amy, encore une fois j’ai apprise des choses. J’étais même persuadé du contraire
Vous êtes les bienvenus
Very interesting Amy.
Thank you Neil! Thank you for the image!
Good information about the narrow bandwidth, Amy. I am a bit envious of your upcoming observatory. Oh, and BTW, if you can't sleep at night, just look at a sleeping cat ... that would do it.
Good to know! lol
Nice one
Thanks for this video. So many beginners need to hear and learn this topic. I have a RASA 11 and use Astronomik's LRGB and narrowband filters. They are made for a f2.2 focal ratio and Gerd, the owner, calls them MaxFR. They are 6nm Ha/Sii/Oiii. I learned about filters the hard way with no one to explain it, but it just honed my skills that much more. Clear Skies Amy! 🔭.
I was always depending on a sales person to steer me right. Really I just want to know why I need to choose something over the other. I have a new set of Gerd Astronomik 12nb MaxFR filters on my shelf now. They are awaiting my next adventure.
@@AmyAstro I think you’ll love them. They are on par with the proverbial and “legendary” Astrodons. I’ve seen many images with them on Astrobin too. Some really wonderful imagery with them.
Nice work! I appreciate all the effort you put into your tutorials with the graphics and effects. Good topic, well explained.
Thank you so much!!!
Great video for covering what is a complicated subject topic for beginners.
Thank you Hogarth!
Hi Amy. Thank you for this video. This subject is the part of the hobby ive been confused with for a long time. Now I'm sure i can purchase and use the correct filters without any doubt. Another great video of yours. Thanks Amy.
Wonderful! Thank you for commenting! I love reading them.
Thanks Amy... So much of that subject that I never knew, especially about the f ratio scopes. I thought they worked on all speeds. I use the 7 to 12 nm, so I see I have the correct filters for my scopes.
Thanks again.
Glad it was helpful!
Thanks for the info, but just using wide bandpass on your filters isn't the best option for faster telescope systems below F4. Filter makers have special "pre shifted" filters for fast systems, this means the peak tranmission is offset to the right of the particular wavelength of interest, When used on a fast system the wavelength gets shifted left and now aligns with the desired wavelength. Thia is all done whilst still keeping a narrow 3nm or 5nm bandpass, just using a wider bandpass filter will allow the shift to occur, but let in way more undsired light/pollution.
I love your videos you explain things so well and in lamence terms which is awesome. I wish my videos were as good as yours but I know very little about editing videos and making them interesting hahaha
Thank you for the compliment. Editing is an on going learning process.
