Night 50mm M Milky Way test
Posted By aitrus3
Replies: 0
Views: 45
Here is a test of the old 50mm f1.7 M lens stopped down to I think f/2.8? Not sure, it's two clicks slower than 1.7 I've never been any good doing that math in my head.
It's only a test because this is only 5 - 60s exposures of the core region of the Milky Way taken with the iOptron Skyguider pro.

Which brings me to another point: I've turned this Skyguider Pro into something rather fun. I'm calling it The Travelling Skyguider, where people can apply and have the unit shipped to them to use for 4 months before it is shipped to another person. The aim is for anyone wanting to learn astrophotgoraphy and may not have the means to buy a tracker or experience/gumption to dive head first into astrophotography with a full imaging setup right off the bat.

Currently open to North American applicants only, because I am broke and can't afford to ship it all over the world.

If you're curious, send me a message or if you know of someone, tell them to email thetravellingskyguider@gmail.com and I will send them the documents and application details.


Can also find it on Instagram @thetravellingskyguider

Thanks! I'd prefer an ND filter but I'd still stack, just not as many images. Shooting at f20 isn't great with this lens, diffraction tends to render tree branches/leaves poorly. I'd much rather keep it at f8 for a sharper image, but, one does what one must. Usually I'll aperture blend but I was rushing and forgot to take lower aperture shots for this set.


Thanks! I took several at this location. This was my first composition and it is by far the best out of the three. Need to learn to trust my intuition, but it doesn't hurt to work the scene a bit.



Thanks Angky!




Thanks! Me too. I know long exposure waterfalls are done a lot but can't seem to not do it; it's the one little change that pushes it just beyond simply documenting the scenery. Also, when I first picked up my moms K10D in 2006 it was always a goal to learn how to do these, so that's another reason for why I pursue it.

Moses Falls near Revelstoke BC on our way back from a small family holiday to Royal Tyrell Museum.

10 images of 1/4s exposures stacked.

Night Miky Way with and without the ISS flyover

I didn't get the still reflection. Traditional milky way photography uses short exposures that are stacked which is how reflections are properly captured. While I had decent stars in the reflections of my tracked shots, once stacked, it didn't work out so well as i thought it would. So adding the reflections back in took a lot of work and I had to minimize them significantly due to a number of factors. I also had to keep the reflections of the untracked shots, which showed long trails, so editing those trails out was very time consuming.

That's a huge undertaking to expand on at the moment for me. Look up Astrophotography star trackers for milky way and there are a lot of articles on it. For stacking the tracked star shots I use PixInsight.
The reflection was difficult because while star reflections were sharp in the longer tracked exposures, stacking to help reduce noise and bring out detail didn't work. Obviously the untracked 4 minute exposures had a lot of trailing in them. The reflections of the stars were glorious on the perfectly still water. If I had done the work to capture them properly, I wouldn't have had such a hard time and the image would be a better rendition of what the camera saw.

Suppose I should post a bit more here... Here is my latest milky way image. the stars are a stack of 30x 60s exposures. FOreground is a stack and focus merge of 6 4minute exposures all at ISO 400. Reflection was a pain to add back in because I didn't shoot it separately from the other two sets, foolishly.

They're leaving quick! I'm excited to do more galaxies this spring. Knocked off Bodes/Cigar, think either Pinwheel or Leo Triplet next.

Thanks Angkymac :) Starnet++ is a star removal program. It allows one to remove the stars in an image so you can work on only the dust and gas. As the dust and gas are a lot more faint that the stars, when you try and bring it out without removing them, the stars get quite bloated and burnt. So as a result, without a star removal program, data can really only be taken so far before things turn quite ugly. Star shape and colour are very important to me. This image isn't perfect, my collimation was out so my stars look like little eggs. Hard to notice on small screens but definitely eggs.

M42 is just below and to the left of the three stars of his belt. You also have Branards Loop, the withc head nebula, Casper the friendly ghost nebula, Horsehead Nebula, flame nebula and a few others that are too dim to see in this shot.

Old faithful M42

Was trying a new composition. It needs tweaking a touch but has potential.

yeah the top one is actually cropped in. It was a crystal i pulled off the ground so it was broken and dishevelled but the centre thin film interference was nice.
Plus, i uploaded from my phone. Not the best quality there.

Yeah it's amazing. Levels works too, but curves gives you more control, it's not just black level or white level but you can affect change anywhere along the intensity curve.

Curves is where colour control is at. Very powerful. Just switch from master to red, green or blue and you can really fine tune things.
