4 Tips to Help you get Better Images of GALAXIES

[@jefff8106]

Love you guys. Information is rock solid and very informative. The thing I like the most is you two are such a lovable couple that enjoy having fun together. Keep up the great work and looking forward to what's next.

[@GalacticHunter]

Thank you so much Jeff!

I would love to hear a tip on how you can combine short exposures and long exposures of a galaxy together using a osc camera

[@williamluong7743]

hdr in pixinsight

[@lukomatico]

Great tips guys! You two are so good on camera haha! :-D

[@SquidwardTentacles-]

Perfect timing for this video 😎

[@GalacticHunter]

Yes indeed :D Thanks!

[@AntharikshamTV]

wow! Great video. which camera did you use? at 1:49

[@GalacticHunter]

Thanks! That night I imaged M13 with the QHY128C! www.galactic-hunter.com/post/m13-the-great-globular-cluster-in-hercules

[@olivierlesage7033]

Thanks for the video. Super helpful tips. You folks are great!

[@GalacticHunter]

Thank you Olivier!

[@MikeTettenborn]

I had never thought to use an HA filter with my OSC. That sounds awesome. I will research right away on how best to do this and how to combine in Pixinsight. You two are the best! Thanks.

[@stevengreen11]

You guys rock. Thanks!

[@nealgrant7727]

Great production very informative thank you, 🌀☄️🌎👍

[@GalacticHunter]

Thank you!

[@astrodojo1]

Oh cool, I learned the Ha part, I had no idea, I guess an OPT visit from me these days, also you guys are cool!

[@chrislarson740]

Great tips guys! Thank you

[@GalacticHunter]

Thanks!

[@avt_astro206]

Some Fantastic Tips for My Progress. Thanks For This 👏

[@GalacticHunter]

Thanks and good luck!

[@Chasingthemilk]

It was indeed super duper helpful. Thanks!

[@GalacticHunter]

Awesome :D

[@tomhoskins4913]

Great job

[@GalacticHunter]

Thanks!

[@wallawalla-astrophotograph4209]

Yes! Galaxy season! All I need is clear skies.

[@GalacticHunter]

Haha hopefully you get a ton of clear nights :)

Unless I'm mistaken (and if I am, please correct me), your advice on cropped sensor cameras is a bit off. They do reduce file size, but that's their only advantage. The dimensions of the sensor have nothing to do with the size of the object on the sensor; that's entirely determined by the telescope and other glass in the imaging train. What matters is the number of arc-seconds per pixel in the resulting image, and that's determined by the telescope and the pixel size of the sensor, with smaller pixel size being better (the object is the same size but covers more pixels). Given the same pixel size, a cropped sensor and a full-frame sensor will have identical resolution. The full-frame will have more black space around it, but the number of pixels on the object will be the same. Since the excess black space can be easily cropped away, there is minimal disadvantage to using a larger sensor with the similar pixel size. You may not be using the full-frame to its full advantage, but you're not losing anything. DSLRs typically have larger pixels than dedicated astro-cameras, so a dedicated camera will generally give better results, but that's not because of the dimensions of the sensor.

The cassegrain may hav a 2350mm focal length, but at the cost of f11 or worse, collecting vastly less light than a newtonian setup at f5. That means with the cassegrains, you need goto, star tracking, lots of computers, and huge stable mount to find and sit on an object a long, long time.

[@astrodad656]

Just have to comment: your graphics are most excellent. Who is doing the vid editing? Nice work.

[@GalacticHunter]

Thank you! I do my own editing :)

[@altrsky]

In general with astrophotography this is a good tip but especially with galaxies. As much exposure time as possible and focus imaging 20percent moon to 20 percent moon try not to go over the 30 percent mark or you will start loosing detail and getting reflections. Any way great video thank you 😊

One big thing is ifn which is amazing for us wide field imagers, I’ve gone down to 50mm and I can frame a lot of ifn. Although it is one of the hardest things to image, so dark skies and a lot of integration time.

[@matthewbrown8679]

How narrow do you go on the ha filter for galaxies?

[@GalacticHunter]

The narrowest I would go for galaxies is 5nm. 3nm is perfect for nebulae but too much for galaxies from what I learned. We only own 3nm filters so we still use our 3nm HA filter for galaxies which is still fine, but 5nm is the sweet spot.

[@forkgmail]

Great video 👍🏻 Just a quick question what is your planetarium software you are using in your videos?

[@GalacticHunter]

Thanks, it's SkySafari

[@nederlandas]

7:31 that's what she said

[@GalacticHunter]

😆

[@GarnettLeary]

An additional tip is to get to as dark a sky as possible.

[@GalacticHunter]

True but we wanted to only include galaxy-specific tips for this video :)

Thanks! Next time let Antoine sit on a chair 😉👍
