I had a full spectrum mode on an Olympus E-M5 for terrestrial IR & astro.  At most I gained 1/2 EV more light.  Having to change filters for multiple lenses was a pain.  A few of my lenses became ...

Hi, Have questions for any of you experienced phonebook makers. Will be starting to use a service to print my images as lay-flat photo books. Will choose a service that uses silver halide printing ...

Yup, that's the one. Good discussion & review. Also some really nice wedges, brackets & counter weight kits from Japan that we never see in the USA. Yes light but expensive. The Light Track II ...

Don't yet have a US price but the U tracker alone is 68,000 Yen - about $650.  And that's w/o a polarscope I think or wedge. Happend to find  this informative extended discussion & setup of both ...

This is a common problem & you'll need to work out a procedure that is successful for you. Jerry is right that you can use the compass & inclinometer apps in a phone to get rought allignmnt. I do ...

Good luck on your efforts. I'd recommend you look up the NPF rule which is sort of what Lonley spec. The formula is simple & allows you to chose how much star trailing you will accept for the ...

Just learned the XT100 will produce 6x magnification on playback images if RAW+JPG mode is used.

Have been using and frustrated with the display on the X-T100 for astrophotography.  Both the XT100 & T200 are rare cameras that have no RAW NR filtering in long exposures.  But the max image playback

Thanks Eric for the replay. I've always waited until after stitching to do background subtraction & stretching in order to maintain a non-destructive workflow. With starry landscapes, the ...

Looking forward to seeing more of this. Didn't know there was such a wizard. Ok answered a question I had - you stitch after background subtraction. Or do you do a partial background removal before ...

Thanks Jerry, sort of what I do now w/ Clearoutside & NOAA. If they agree, my odds are better. But from my experience shooting starry landscapes, the location I'm attracted to - coasts & mountains ...

Great resource, thanks Jerry. Have a basic question about services like MetroBlue and phone apps like Xasteria that offer choices about forecast models - how do you use thse or make a model choice? ...

Have never used a Bahtinov mask so not sure.  But I,d guess it would work well because you can stop touching the cam & look for the x. BTW, we are now in the long cloudy season so may be awhile ...

The old one hotspots @ f8 or smaller for 650-720 nm. That stopped me buying it.   Hope this one is better.

Only way to know for sure is try. I'll rent before I buy for both this reason & to see how easy it is to focus. The T100 does well stacking but not so well focusing. The other thing we don't know ...

Got a used Samyang on eBay & its much sharper than my XF56 wider than f2. Have used both for astro where I MF stars. My XF56 is soft especially at the edges. If you are judging sharpness of XF56 ...

Wonderful massive detail! Amazingly tight stars given the roughly 2.75x crop factor or is it? f/2.0? Focal reducer? Looking forward to updates on this project.

These objects require longer FL than you'll get from a lens.  You'll want a good tracker for these & w/long FL will find it hard to frame these objects.  Suggest you are starting at the wrong end ...

Thanks for the explanation.  Fortunately, it doesn't show with a very hard stretch at least on a single 8-min. dark frame.  So maybe not a problem.

Ouch.  Looks like banding or line noise could be a problem with the XT200 when stacking lots of frames for astro.  Is this from the PDAF pix on sensor? Interestingly however, DSNU for both cameras ...
