Mars taken on September 21st (RGB)

[TheButcher]

Hey all,

Here an image of Mars that I took last night. The seeing was about average and the sky clear except for some of that smoke haze that we all love. I started without a Barlow with my 290 then used my 1.5x Antares Barlow and it seemed to be ok then after this image the seeing got poor and had to back down to no Barlow. But luckily I got a set with the 1.5x, it could be more as I pulled the camera back a little bit.

Imaged with

Celestron C11
iOptron CEM70
ZWO 290mm (Non mini)
ZWO R,G,B filters
Antares 1.5x twist Barlow
ZWO EFW filter wheel

Captured with FIre Capture and then went to Auto Stackkert2 (7% stacked) then to Photoshop to combine the channels, then off to Registax for a little Wavelets then back to Photoshop to get the final image.

I didn't feel like going into Win Jupos yet so I just took the image and split the times down to equal 280 seconds.

Also, Does anyone have any suggestions on how to do Mars in Win Jupos for exposure times and sets? (For example... 200 seconds per channel x 2 sets or so).

RED 110 seconds (About 30,000 frames)
Green 85 seconds (About 14,000 frames)
Blue 85 Seconds (About 14,000 frames)

Thx for Looking

That is a fine and nicely detailed image of Mars!
Am I wrong, or do I even recognize a Mars Volcano (Arsia Mons)? The bright dot at upper left?

Beautiful shot(s) Butcher!

I really like the colors that you achieved. The surface looks great with nice details and the ice cap is super white!

Excellent work!

Thanks guys

Here is the Red Channel really stretched and such to see the upper left corner. It appears to be something, But I am not familiar with Mars terrain yet

It is a bit difficult, as far as I know ( I am no expert either) to make a difference in this case between a volcano, orographic clouds and maybe even a dust-storm, or just areas with a higher albedo
The three volcanos Arsia Mons, Pavonis Mons, and Ascreus Mons lie from left to right in a row, and the white spots seem to be in the right place, top left. There are more distracting white "hotspots" though. On top left ( at 23.00 hours) there is a somewhat bright spot, surrounded by a darker circular area. There is little doubt in my mind that we deal with Olympus Mons here. ( the largest volcano of the Solar system)
The fork-like shape in the middle of the original picture is part of Vallis Marineris.

Thanks for the info john I am fascinated with Mars and need to start studying more on the landscape and nature of it and hopefully, no duststorms appear like the last one and also no smoke haze here when opposition happens. It is kind of ironic how 2 years ago the Dust storm happened on Mars, now, here on Earth in the US/Canada we have a Smoke Haze and appears but it seems to be clear on Mars nearing opposition.

Thanks for the image and all the good Mars info.

Hey, that is one great image Butcher, I think that position is about right for Mons. If it is Mons is a bit hard to be sure.

Thanks MIchael and Tony

I think I will check out some of the images I took before it that was without the Barlow and had more detail possibly. I got some Lums I took as well.

The Barlow will magnify the atmospheric dispersion so that data will look better. As you are splitting the channels that will help and registax is helpful too with the rgb. Mars is at its highest dec. of 63 degrees and it won’ be back there until 2025, so it's time to fill our image banks.

For Xmas I think a ZWO ADC is in my future.

Thx for the tips Greenman

Also, Greenman and John, I did another Mars that was taken about a half-hour before I think. This one was without a Barlow and I think you can make out some of the details better and see the three volcanos Arsia Mons, Pavonis Mons, and Ascreus Mon in the upper left corner.



Same image but I enlarged it to see it better
