A Martian Epic

[astroavani]

On 2018 Mars gave a real show... therfore, I could not fail to register it!
This composition, made with an approximate an interval of 10 to 15 days between the photos, starts on July 31 when the planet reaches the largest apparent diameter (24.3" arc) and ends on December 5 when it was with only 8.9" of arc.
Three things stand out in such a work: first, the sharp reduction of Mar's diameter as it moves away from the closest approch to Earth; second, the phase decrease as it approaches the quadrature and finally, the marked reduction of the Southern Polar Cap, which in the last photo is reduced to a small point.
The Greek Goddess of Victory, Nike, is the source of my inspiration. Likewise, Mars has won not only my expectations nut also has won my longings and brought me the feeling of having witnessed an unforgettable epic event!
Mars positions in this composition were inspired by the stylized shape of one of Nike's wing".
PS: This was a composition was sent to the Insight Investment Astronomy Photographer of the Year 2019, therefore it was never published anywhere. Although it was not selected, it now deserves to be shared with the astrophotography community!

Stunning sequence, wonderful views.

[Ozypic]

Very interesting , thanks for sharing it . Phill

[The Happy Parrot]

Superb.

[Ruud]

That is such a beautiful presentation.
Great work!

[bladekeeper]

Excellent work!

That is such a beautiful presentation.
Great work!

Na verdade amigo Ruud, eu creio que essa foto não foi selecionada no concurso única e exclusivamente por lembrar o símbolo da Nike.
Vá lá e olhe a imagem que ficou em primeiro lugar, veja como é o mesmo tema da minha, apenas ele não usou um formato que lembra o simbolo da Nike.

In fact friend Ruud, I believe that this photo was not selected in the contest solely and exclusively because it resembles the Nike symbol.
Go there and look at the image that came in first, see how it is the same theme as mine, only he did not use a format that resembles the Nike symbol.

I really don't think mine has gotten much worse!

Really wets my appetite for Mars this Summer. Although I'll be lucky if I can make out the polar caps in my images! Really nice composition and super informative.

Hello colleague starfield
I happened to see that you have a 12.5 "dobs, as I reckon it is from California I was interested.
I'll explain why:
I bought a used telescope of American origin that was a 12.5 "f / 6 dobs. I know it is an ATM mirror by the inscriptions that it has on the side edge. It is an old pirex mirror with a 15mm thick secondary and 65 mm on the smaller axis .
I tried to find out the origin but I couldn't, would you happen to know something like that? Did you know any information?
It seems that yours is very similar.

Notice the initials LK on the edge!

A beautiful showing!

Ah, the other one is beautiful too, but I do prefer yours. It has more orbs and a more interesting shape.

Everyone is hoping the best for next opposition, like clear skies on both planets. To get in the mood I bought a Mars globe (one from Mova, see here).

Congratulations Avani on having your image selected as todays TSS APOD!!

[AstroBee]

Congrats on the TSS APOD! Those are some amazing captures. The detail on the surface is almost like nothing I've seen from ground-based scopes.

[TheButcher]

Wow that is really great Astroavani! And congrats on the APOD!

[helicon]

Great sequence of images. Super impressive work. Congrats on winning today's APOD Astrovani!

[Ylem]

Nice!

[Makuser]

Hi Avani. This is superb chronological sequence of Mars. Excellent cap and surface markings. A fantastic job of imaging with the 14" Edge HD telescope. Thanks for taking the time to put this great work on here for us Avani, and congratulations on winning the TSS APOD Award today.

Astrovani, I really don't know how to trace origin on this mirror. I'm thinking that if you post something over in the ATM section you may have some luck. An F6 12.5 inch will be a lot of fun to look thru without having to manage much coma. (I'd just need a step-stool to get to the eyepiece.) If you're looking to repackage the optics in a new tube or truss, send me a message and I can send you a few bookmarks of some kit makers which is the route I took.

I appreciate the offer friend Starfield
I actually have a friend in Brazil who works exclusively with telescope mechanics. I will make it entirely in carbon fiber in the Truss style, similar to the one in the photo below.
Currently the main mirror is being tested with one of the best ATMs and optics in Brazil. I will only make this tele with the best possible material if the optics match my expectations.
At least I expect 1/8 PV of the wavefront.
The idea will be a replacement for the C14 in the near future. Newton always liked me more in the generation of images, I already had 2 of 300mm f / 5 and found the image more natural than the C14.
They are simpler and purer systems, a C14 Edge in addition to the two mirrors has a lot of glass in the path of the Light, apart from the obstruction that reaches 32%, since in what I intend to do it will be limited to 20%.
Anyway it is a project that I want to develop without haste.
