it would be a good time to publish an APOD with Jupiter and Saturn to encourage people to observe them. They are close to each other in the sky and we are near opposition (July 14th ofr Jupiter and July 21 for Saturn).
I did these images the same night on july 22th from my balcony in Paris with a Mewlon 300, they are at the same scale. Getting high resolution images from Paris is not that easy because they are at 18 and 19°.

This is created from 66 x 60s exposures through a Blue filter for maximum contrast. July 23, 2020 from 9:06 PM to 10:17 PM PST.

The comet was tracked with a direct drive Planewave L600 mount at .5 arcsecond per minute drift error for over an hour. There's one minor position "pop" (cause TBD).

All 66 frames were then calibrated and batch processed with Pixinsight Automatic Histogram Transform (through Blink) followed by HDR and LHE.

Video rendered from processed PNGs using Photoshop. 1920 x 1920, H.264 @ 20 fps.

My re-reprocessing of July 20 image of comet 2020 F3 Neowise.
This time I use 49x 1 minute images to make this composite.
Just for curiosity you can find the NGC 3079 in the image.
I use a Nikon D800 , Nikkor 180 mm 2.8 ED over a Star Adventure mount

Enjoy

COMET C/2020 F3 NEOWISE -----> SODIUM TAIL

Close-up image of the coma with ion and dust jets. Second image shows sodium comet emission,
with a professional filter by Andover Corp. 589.3nm 67% transmission Bandwith 50% 1.94nm.

--------------------
"Its [atomic sodium's] momentum kick comes from a very particular wavelength of yellow light — the same color seen in sodium vapor street lamps," research team member Jeffrey Morgenthaler, a PSI senior scientist, said in a statement.

"Thanks to acceleration by intense sunlight," co-author and Boston University research scientist Carl Schmidt added in the same statement, "the sodium tail takes on a different shape than the tail seen in off-band filtered images, which are dominated by reflected light from dust. In comparison, the sodium tail is narrower, longer and points directly away from the sun."

Sunlight's push on sodium atoms tends to be stronger than its effect on dust and other gases that come off comets. It is difficult to see sodium tails, however, due to the sun's emissions. Notable examples of comets with sodium tails include Hale-Bopp (the famed 1997 naked eye-comet) and the notorious Comet ISON, which fell apart shortly after rounding the sun in 2013.

Morgenthaler and Schmidt will continue to observe NEOWISE as it rounds the sun. They are also using Monte Carlo computer models to simulate the sodium tail and estimate outgassing rates and speeds.

It was not revealed in the statement exactly when the team plans to submit their results to a journal for peer review, but it is common when observing quickly changing astronomical phenomena like NEOWISE to release interim information to keep the community informed.

Comet C/2020 F3 NEOWISE, with the International Space Station, on July 20, 2020 between 10:08pm and 10:23pm, from Burlington, Ontario, Canada. This is a composite that incorporates 21 frames of 3.2 seconds each, taken with a Canon 40D and Canon 100mm lens.

The ISS passed through during my 10:08pm exposure.

Hello ,
this photo taken from Mount Moses summit
Saint Catherine , Sinai , Egypt

i Managed to climb the mountain at night and setup my tools and just waiting for it to appear before the first sun lights hit the horizon just enough to illuminate the view and you can see down there saint catherine cathedral and the 40 Valley

such a great pictures people congrats!

I am going to share one found in flickr, the author it is pretty nice, due the pic is published as CC.

By the way, I would love to do similar pics, but checking the cams you guys posted and this one, looks super expensive, any cheaper solution?

I was looking at some Kodak cameras, and by photo and reviews looks pretty good. However, it is triggering my attention that looks pretty cheap compering with Canon and Sony cameras, as you can see on this list of prices any idea?
