Hi all, here another image from February 14th session under fair seeing and
average transparency, likely the poorest one of this session.
Just 30 frames averaged for this image with another classical lunar zone causing some excessive graining.
More to follow.
Thank you for your attention.
Hi all, During last weekend of March I drove on southern Tuscany to relax myself and I also brought my scope given the nice weather forecasted.On Friday 28 a 100 km/h jetstream overhead turned a steady Saturn as smooth but on the following night it died down enough, so I had a fairly good seeing.
Moons all way around looked like small diamonds at the eyepiece! What a nice view!
No spots detected over the 2 nights at these longitudes, but I’m amazed indeed in having captured the weak Enceladus moon so close to the bright Saturn disc and, above all, the even weaker Mimas “shining” at 12.8 magnitude with a filtered exposure as short as just 60 msec!
Transparency was excellent and the sky ink black, no wind and no dew at all.
SATURN MARCH 28
SATURN MARCH 29
The 2 images were captured from Villa Tatti, the best italian villa I know!
Thank you for your attention.
Hi all,
Here another image out from February 14 session under mainly fair seeing and average transparency.
A classical view of a well known area with the Sheepshanks rille popping up on the top-right corner.

Thank you for your attention.
Hi all,
Here another lunar image from February 14. Fair seeing and transparency.
On highlights, the nice Hyginus-like appearance owned by the crater lying aside Licetus C crater. It looks like a crater caused by a ground collapse.
Also, notice the nice difference between the Stofler rough floor and the smooth Maurolycus one.

Thank you for your attention.
Hi all,
After a 4,5 months dry spell caused by weather, I could capture new stuff on last February.
Fair seeing an transparency on Feb. 14 when I captured this wide lunar south pole strip starting from Moretus - filled with shadow and a dotty central peak - ending up to those unusually bright terrains placed just southward of Hagecius crater.
A favourable libration could face us craters usually seen on the limb or behind it such as (from the left to the right) Schomberger, Scott, Amundsen, Hedervari, Demonax, Hale and much more.
As note apart, I noticed an error with the Virtual Moon Atlas software placing the terminator much westward than it appears here in my image. The VMA for that date shows me Moretus crater almost fully illuminated! Can someone explain why this incongruence?
More to follow.
Thank you for your attention.
NOTE
Christian Legrand - one of the Virtual Moon Atlas author - was kind enough to clarify the “error” noticed by myself in this image.
This software, as any else lunar simulator do, is rendering the lunar surface as a perfectly flat sphere with no irregularities at all. Thus, depressions, tall mountains and crater rims aren’t taken into account to get the true terminator out as we can see at the eyepiece at a given date. The night/day border line is thus to be considered as a theorical line which might not precisely reflect reality. This is most true in the battered lunar South Pole where the ground is all but flat!
So, we should consider this as a limit of the software, not an error as I stated a while ago.
Thanks again to mr. Legrand for his clarification!
Hi all,
I take this opportunity to proudly introduce you the new restyling of my personal website so nicely done by my dear friend Davide Del Vento (thank you so much, Dav!) who spent his own free time in making all of this and, above all, in making me convinced this solution was the way to go!
After having missed a good opportunity of catching Mars from here in Lowres Land, the same would have happened also with Saturn if I wasn’t so brave to push myself beyond my limits!
So far, I never considered a multipoint alignment also with Saturn, neither the manual hand picking of the raw frames, neither the stacking of several images captured over different nights. But all of this was due in order to have a decent image at least for the 2008 and not to trash any single image captured on last February.
At the end, I stacked 2800 luminance frames out of 80.000 (1 out of 28, a thin 3.5% only!) captured over three nights across the opposition to put Saturn 2008 banding in a nice show.
I only hope this is the first time AND the last one as well I’m forced to do this!
Hi all,
Find here my latest and widest shot showing the sunset on the Appennines
-from Cassini down to Eratostenes- and lot of jewels setted anywhere on
the eastern side of the mare Imbrium.
Fair seeing as always with the first two shots composed as planned, the
bottom shot with Eratostenes area was taken an half an hour later with a
fairly good seeing and added to the scene with no preliminary plan!

Much to say and to study here!
On particular, my attention was caught by the very wide and smooth
dorsae (?) which begins from Theaetetus (the big crater south of
Cassini) and runs northward parallel to the Caucasus mountains. I never
noticed it before!
Enjoy with this 12 Mpixel sized mosaic at the full resolution, no more
image will come from me.
My HDD is now empty.
Hi all,
Second image out of the 3 composed over that session.
Given the 15 minutes recording time difference between the 2 images
(making shadows stretching in the lunar ground), the changing seeing and
the changing contrast due to the Sun rising over my site, this was all
but an easy montage!
But there is nothing better than getting rid of all such problems!

Ciao,
Il 3 ottobre ho registrato la mia ultima sessione di riprese lunari, da
quel giorno nulla più.
Seeing stabilmente discreto con alcuni buoni momenti verso l’alba.
Questa è stata la prima ripresa:
http://www.lazzarotti-hires.com/images/moon/deslandres-regiomontanus-walter20071003_lazz.jpg
Da notare la presenza dentro Regiomontanus (in alto) del cratere più
“vulcanico” che ci sia sulla Luna!
Alle prossime.
Hi all,
My last hires lunar session recorded on Oct. 3rd was my latest one so
far. No new image from then.
I had some steadily fair seeing over that late night peaking to good at
dawn.
This was my first shot grabbed:
http://www.lazzarotti-hires.com/images/moon/deslandres-regiomontanus-walter20071003_lazz.jpg
To be noticed the weird volcanic-like crater inside Regiomontanus on the
top of the image!

Hi all,
On Dec. 28th I met my friend Nicola and we had a session on Mars with
his own Orion 250mm newtonian featuring optics which left something to
be desired.
Seeing mainly poor with a fair window lasted enough to grab the 3 RGB
streams. The small image scale allowed a fast exposure (1/30th sec.) and
a low noise (less than 10dB) to better freeze the turbulence. The Iris
drizzle (2X) worked beatifully indeed! I didn’t expect such a result!
But as always happens, the boring side is facing me whenever I grab Mars
under acceptable conditions. So, the B image is much more interesting
than R, you can see there the 3 lined up orographic clouds over
vulcanoes and the isolated Olympus cloud on the right.
Also, notice the completely dissolved NPH making the thiny NP with its
dark collar popping up nicely.
