    Jupiter and Moons

    Yes, the moon is full right now. Other than the moon, Jupiter is the brightest object in the southern sky right now, so keep looking.

    Jupiter and Moons

    Jupiter is very close to the earth right now, it is the brightest thing in the sky, other than the moon, and it's about straight south at about midnight, the last few days or more now. Not hard to spot, except the moon is getting brighter at this point. You can probably find it in a clear...

    Nothing like that, just a tripod, no tracking.

    Jupiter and Moons

    I could not find an astro category, is there one? Jupiter and Moons, 6-13-2019. Not my best work, but still worth the try. Had equipment snafus, took forever. ('some' of its moons) I have been hearing Jupiter is close to the earth right now, so... had to give it a shot, or two, since it's up...

    Thank you very much, I really appreciate your comment. Refreshing.

    Here is another Hrommagicus 3 shot stitched panorama.

    EIR/Aerochrome Semi-Simulation Lee #729 + Schott KG3

    Here is an interesting snap shot, showing big red flashing railroad crossing lights, yet you see no red light. Also you see no red on the lowered crossing arm. This is because the Hrommagicus filter blocks visible red, and in the case of these red lights and red striped barrier arm, there is no...

    My goodness, I didn't know you were on here...! You are so kind! Thank you very much! ?

    Try it if you want. :) The truck belongs to someone else, I've never tried jump starting it. Hrommagicus filter A spooky old house in among the filbert orchards in the late afternoon.

    EIR/Aerochrome Semi-Simulation Lee #729 + Schott KG3

    Here is a graph close to the transmission of Hrommagicus. Note how the visual red is suppressed. See how the blue and green range is transmitted, and how 720nm to 920nm IR is transmitted. Here is an example of the the filter stacked with S8612 which suppresses everything above 700nm, so IR is...

    EIR/Aerochrome Semi-Simulation Lee #729 + Schott KG3

    Most of the color? So the sky is not blue you mean? What it transmits is visual blue, visual green, and replaces visual red with infrared. It only drops visual red, but replaces if with IR. So anything that is red is reflecting IR. These are landscapes, so they have mostly foliage in them...

    EIR/Aerochrome Semi-Simulation Lee #729 + Schott KG3

    A few more. The filter I have made has been redesigned, it still works essentially the same way. The name of the filter is Hrommagicus, these are SOOC.

    EIR/Aerochrome Semi-Simulation Lee #729 + Schott KG3

    Asher, The front has a KG3 2mm filter in a ring, and a Lee #729 gel type filter in a ring, stacked. Nothing to unusual looking. Visual... Well, of course one can use this full spectrum D7000 for visual also, I like Schott BG38, BG40 myself. Of course I have a few other stock cameras that are...

    EIR/Aerochrome Semi-Simulation Lee #729 + Schott KG3

    Asher, basically the whole idea with this simulation is not to use Photoshop for much of anything. Aslo, if you want B&W IR, then just use some IR Longpass filter, 850nm is my favorite for black and white, 830nm works also, even 780nm, that is a much better way to do B&W IR than converting this...

    This is not my invention. The formula was from David Twede, many thanks to him. https://next-eyes.blogspot.com/2018/11/my-history-re-inventing-digital-ir.html?m=1

    EIR/Aerochrome Semi-Simulation Lee #729 + Schott KG3

    Hi When I say "semi-simulation", I mean that this filter stack only puts IR in the red channel, it doesn't do a true 'transposition' of IR > Red, Red > Green, and Green to Blue like EIR/Aerochrome does. So for example, visual red doesn't change to yellow as it does with EIR (look at the tail...

    Bob, Unreal, that takes the cake, great colors also, and maybe one of the first fisheye shots I have seen where the blue edge actually goes good with the photo and doesn't need to be removed. Can I use that as my avatar? ;-)

    RG665 Portrait

    The only reason anyone is looking at this topic is because we are arguing. Not because of the portrait I posted. Someone on the planet disagrees with you. People tune into CNN for that stuff all the time. I don't think either of us is involved in this discussion to get attention, it is just...
