It's a Triplet Mark, one of the first TMB175 No.31. The objective lens weights 7Kg

Very nice! I think Walter had the 180mm doublet...

Interesting video of the Maxim DL processing-stage Pedro and thanks for sharing.

One of these days (nights) if I can get to the stage of decent DS imaging, I would purchase Maxim DL, but the night-sky pollution is still quite bad here, even though some nearby street-lighting is turned-off at midnight or 0100hrs(local).

Wow, you know how to surprise. A stunning telescope, stunning details of the moon and deep sky objects. Have you planned to try shooting the Sun with it?

Thanks Ivan

I do not plane to image the Sun with the TMB175. I built a third observatory to house it together with a Paramount ME. I have a 180mm f/6 APM Achromatic that I will use to image the Sun though

Thank you Pedro. Coronado filter next to such a monster looks like a finder. Great, you surprised me again. Hats off to you.

Excellent captures through the TMB175 scope Pedro.
M33 certainly shows much detail, so thanks vm for sharing

Many thanks again Pedro for the interesting animation.

I will never likely get to the same standard of the night-sky imaging that you have reached, as your weather and temperature is significantly better than mine, but it certainly shows what can be achieved with the same dedication that you have shown for all your imaging.
Although my main-obsy does have a warm-section, to operate there for longer periods of time, at my age, is not easy...

But at least looking at your images and the gear too, certainly is well nice to see - thank you.

Regards
Terry

Thanks vm for your latest captures of M74 and M1 Pedro.
I was wondering if you captured (or tried to) of Comet Leonard (C/2021 A1) and its' close encounter with globular cluster M3 :?: :?:

Becoming Magnitude 4, it looks as if it could be a good capture and of course is actually lit by our Sun !!!

I certainly would be interested in seeing such a capture(s) and weather permitting might get to see it myself...

Cheers
Terry
