Leo I is a dwarf galaxy in Leo constellation. It is also the most distant satellite of Milky Way.
The object is extremely hard to observe because of really low surface brightness and also proximity of Regulus.
You need good dark sky and nice transparency to catch this object. It is one of the small “night challenges”
I made a small compilation for some asterisms. These are not popular objects, and few amateur astronomers watching these group of stars. I think, you find very pretty star clusters in these catalogs: Alessi, Teutsch, O’Neal, Harrington, Slotegraaf, Ferrero, Markov, Streicher, ESO etc. You can see a lot of binoculars, and small telescope. I used this telescopes: 15X70 binoculars, 130/650 Newtonian reflector.
I send one sketch from january of C/2014 Q2 (Lovejoy) seen with 50X magn.
in my telescope. I could see two faint stripes in the beginning of the tail.
I used pencil (9B) on white paper and inverted. Info on my sketch.
Loc.: Trondheim, Norway.
I also used 10 x 50 binos, and could see a longer, faint tail to east!
Apollo 15 Landing Site
Last evening proved to be a fine night for observing the Moon and the planets. The atmosphere at sunset settled down to a Pickering 8/10 and 9/10 for brief intervals. This was predicted so I had two telescopes outside (my 18 inch f/4.9 and 13.1 inch f/6 both Dobsonians). At 373x using the 18 inch scope I could clearly see the floor of Palus Putredinis (The Marsh of Decay) and not far away Rima Hadley at the foot of Montes Apenninus. I spent a 3 hour interval on this sketch but actual sketching time was more like 2 hours. The sketch was done using the smaller scope because it is driven. 4 mm and 6 mm eyepieces gave me magnifications of 499x and 333x and occasionally I used the 18 inch scope to verify some of the meanders of Hadley rille and other small features. I have marked the landing site (red dot) of Apollo 15 Lunar Landing Module which occurred the summer of 1971, a very exciting time for the US space program.
Craters visible in this sketch include Hadley C 6 km. in diameter and Aratus (10 km.).
For this sketch I used: Gray sketching paper, 9”x 11”, white and black Conte’ pastel pencils and blending stumps.

M5 is undoubtedly one of the finest globular clusters we can observe with our telescopes, But I have to admit that I was not able to show all the beauty I saw through the eyepiece, better to take a look for yourselves .

I was delighted this morning to find this dark and large filament at the north-eastern limb of our Sun. It had the appearance of a large serpent with foot like projections anchoring it to the solar surface and then visible curving around the limb. The filament is magnetic curtains of plasma hovering over the Sun’s surface, this an especially large and detailed one. I read on the Spaceweather site that the length of the filament would measure the distance from the Earth to the Moon. That’s one big serpent!

On April first at 23:00 hs. in La Matanza, Buenos Aires, Argentina, I sketched Acrux, the brightest star in the constellation called “Southern Cross”, “Crux”, etc. This star is also known, in religious terms, as The Foot of the Cross, due to obvious location reasons.
It’s a nice double-star system done in white paper, with graphite 4B, 2B and HB2 pencils; after edited with Photoshop tool, while observing with a Newtonian SW 150/750 f5 telescope.
I liked the final results, so hope you like it too!
I went out to sketch the AR 2339 in h-alpha but when I saw this massive Hedgerow type prominence on the limb it had to be done.
