Astrophotographer 10

Noice ! My Kiwi friend. Greg. Aus

Unfortunately this is all true so you can see how the costs rise rapidly in this hobby. Stick with a DSLR/mirrorless cam to start or get a cooled colour version of a ZWO or QHY camera and go from ...

He should get the cooled version of the camera not the uncooled. Narrowband is noisy imaging so long exposures and decent cooling are vital. Noise drops a lot with cooling. Usually something like ...

Its very brown with no colour. What white balance setting are you using. It looks like daylight setting which looks all brown and yellow before processing adjusting. Try adjusting the white balance ...

At the moment the Milky Way is well above the horizon as soon as its dark - around 6pm at the moment in Sydney. The core of the Milky way though is directly above us around 11-12pm. So if you want ...

Perhaps you got a bad copy. I have used the 55 1.8 several times and it was great. I may have stopped it down a bit though, F4 and longer tracked exposures. Greg.

That is very helpful - thank you. Greg.

Yes it is the Emount version. Good advice, I realised y wife has a Sony 6000 camera so I'll try the lens on that if it fits an APSc camera. Greg.

I only see Leica, Nikon and a few others but not Canon. If not is there an adapter? Greg

You'll need a good tracking mount to use a 400mm lens. It will be easy with a proper german equatorial mount but it won't be easy with the usual lightweight nightscape trackers. You could take say ...

I am reading a recommendation for Voigtlander APO lenses being best for nightscapes and astrophotography but I can't see any for sale for a Canon mount. Do you know if there are or if not is there ...

A magnificent image Eric. My hat is off to you. There are a few objects in there I haven't seen before. That bit of dusty nebula with a bit of blue reflection nebula in the bottom right looks cool. ...

I got a Sigma Art 35mm F14 FE mount and it worked for a while. But then mysteriously the aperture no longer responds to controls and is stuck at around F16. I thing there is a more recent firmware ...

I use some smartphone apps. I set south (I am in the Southern Hemisphere) using the compass app. It seems quite accurate and I don't think its affected too much by the metal in the tripod or camera. ...

With my Canon EOS Ra I use 21 1.8 or 14mm f1.8 or perhaps stop it down to 2.8. I use 30 seconds and ISO3200. You can of course use lower ISO but not too low. See the Lonely Spec site for lots of info.

Not exactly what you asked but I have the Sigma Art 14 1.8 and 35 1.4. Both have considerable coma which seemed to get worse with use. I have had 2 Art 35 1.4 fail on me so I am not sure about ...

What Jared said. If you want maximum Ha response you need to get the ZWO or QHY version of that sensor. That is the QHY268mc or the ASI 2600C. These are still one shot cameras but they are cooled ...

There aren't many lens choices for Canon for Astro believe it or not! There's a tamron 35 1.4 that is supposed to be good. I have a Samyang 20 F1.8 but it wouldn't focus to infinity. I did a bit of ...

A bit too brown for my taste. The sky should not be brown. The MWay looks a little dull and mono coloured as well. Otherwise a good effort. Greg.

Any sort of mosaic should have each panel processed the same way or you'll have tremendous trouble trying to get a seamless mosaic. The only difference may be freeze ground as that should not ...
