Astrophotographer 10

Sensor heating for Milky Way is not an issue here in Australia where we are midwinter and it could be 1C out in a field. I haven't seen sensor heating as an issue even in summer but mirrorless is ...

Nice work. That Astrotrac must be awesome to handle a 400mm lens. I should upgrade at some point to one of those. I notice there are a plethora of APO telescopes that are reasonably priced that all ...

Hi Mark, I just did a quick and dirty test and it seemed to handle it well. As far as foregrounds and stars I don't think its going to handle the blurring of the foreground from stacked images. ...

This new free Kandao software seems to be very promising. It aligns and stacks RAWs from major camera makers and is very simple. https://www.dpreview.com/news/5684086579/kandao-raw-is-an-automated- ...

Overall a very nice image. 3 x 10 seconds is very short exposure. Try 6-12 shots per tile. The more the merrier. I would not worry too much about the movement of the sky. At F1.8 the 55 1.8 does ...

I just read this DPR news item and tried out the free aligning and stacking program. https://www.dpreview.com/news/5684086579/kandao-raw-is-an-automated-image-stacking-tool-for-raw-files It seems ...

What they all said. ISO200 pushed would require a very ISOless sensor and I am not sure it is. At the least you would expect some colour shift from pushing that hard and at the worst extra noise. 2 ...

That is superb! One of the best nightscapes I have seen on this site. Fabulous colour and saturation on the Milky Way and such a great scene and framing. Greg.

Very beautiful photos. Greg.

Lovely. Sounds like a dream trip. Greg.

Its not really that simple unfortunately. A lot of lenses are hopeless wide open so it depends on your lens. 30 seconds is too long for lenses longer than about 20mm. I use a Loxia 21 and untracked ...

Uncompressed RAW, manual focus, steadyshot off (its IBIS and its in the menus). 30 seconds ISO3200 F1.4-F2.8 depending on your lens. Best lenses: Samyang 14 2.4 and 2.8 (cheapest but quality varies ...

An impressive image if you managed to capture that without a modified DSLR. I'll go with 6D, Sigma 35 1.4 and say 20 exposures at 90 seconds? I wonder if you used some slightly overexposed shorter ...

A lovely image. Greg.

Nice shot for a first attempt. My only comment is M17 is not magenta/lilac. So your colour is off from somewhere in the capture settings or processing. Greg.

I don't know about other brands but with a Sony full frame the speckled colour noise in shadows is somewhat random so darks don't really correct it. They do remove a bit of amp glow that I have ...

Wow, fantastic.Oh la la! Greg.

I like some of the shots. Its all good experimenting with different processing. We don't want all photos to look the same. What does ROG Stand for? I haven't heard that term before. It seems to ...

That's very interesting. Of course Sony makes a large body mirrorless with the A99ii. Will they bring out an A99iii? Hard to say as Sony execs have said A mount is not dead but also have said that ...

Quite possibly although Laowa seem to be good at making zero distortion wide angle lenses. Greg.
