Having said that, how good is Sky Safari??? It tracks like the dickens, and once aligned is quite a bit easier to use than Stellarium in my opinion. Generally I was using my Baader zoom at 150x, but also used the ES 4.7mm for a bit more power, although I found the atmospheric conditions and breeze at 255x sometimes made the fainter stars almost disappear.

1. DELTA CORVUS - ALGORAB: This is a wide delightfuI pair mags 3,9.2 ; Sep.24.2” , PA 214°, easy to find, easy to see and an interesting coloured companion ..PURPLE?..can use large high power Binos.
Easy split, and while I wouldn’t say the companion star was purple to my eye, it definitely seemed to have a dusky glow to it.

2. QUADRUPLE HD109545 or AKA, Stf1659:

AB Separation 12.4", Mags ,6.7,15.5... at PA 248°, and Stars CD : Mags 7.9 , 8.34 at Sep 27.5" : PA 351°...So 4 stars!
Not sure if I got the right level of magnification for this, but I saw a small, faint isosceles triangle of stars, surrounded by a much larger and brighter inverted equilateral triangle of stars.

3. TRIPLE STAR
HR4821 and HR 4822 or called Struve 1669..........also called VV Corvi:
A beautiful trio of AB: Mags 6.0,6.1 at Sep 5.4” with C component, at mag 10.5 and Sep 59” in the FOV.
This is a nice little trio. Couldn’t detect any appreciable colour differences.

SOMBRERO GALAXY only 1.25 degrees north of VV CORVI!..take a peek!
Averted vision just made out a slight vertical slash of light, but certainly nothing to get the pulse racing under the conditions last night.

4. TRIPLE STAR HD105590..AKA Stf 1604: AB Separation 11.2", Magnitudes 8.47 ,10 at PA 151°.... MAGS BC: 10, 6.8 at Sep 9.0" and PA 89°... YELLOW , Blue/ white What colour contrasts do you see?
Made this out as yellow-white, blue-white, and maybe a dusky reddish colour. A French flag triple.

5. DOUBLE STAR
HD107501 or also called ADS 8524 : Sep 5" mags 10, 10.2 WHITE, RED..and you?
Quite an easy split for this one.

6. DOUBLE STAR
HD106955 , AKA.. Bu 921, SAO180662: Mags .... 7,10.7 at Sep 3.4" at PA221°..Any colour Contrast?
A pretty tight split for me, and the companion star was very dull compared to the main star.


7. DOUBLE STAR h4481 HD 103817: This is an almost equal pair of mag. 8.0 and 8.1 stars, Sep 3.6” and PA 194°. Located near Epsilon Corvus.
Easily split with medium power, I see them as LIGHT BLUE twins.
Just got this one, again no appreciable colour other than whitish.


8. TRIPLE STAR
HR 4758 .. AKA... BU28 : Sep. 2.2” mags 6.5,9.6 YELLOWISH and WHITE in 130mm Apo at 275x with Tak 3.3mm Toe ..with another fainter mag companion north of field.
Very difficult this one, but just got it.


9. DOUBLE STAR HR 4661 or Bu 920 also called HD106612: Sep 1.9", mags AB 6.5,8.2 at PA 308°..tough but done at 150x with 6mm Tak Abbe or even 5mm Dual ED, easy with 3.2mm Dual ED at 285x
This was probably easier than HR4758 – pretty easy split, and I was seeing white and orange.


Thanks BigJoe, looking forward to April's list.
Thats GAS Gaseous..
Great results for all these VV CORVI is a very pretty find for anyone..AB both ORANGE TO ME.
AGREE No . 8 being easier than 9 as both its main components have a lesser MAGNITUDE DELTA..

And No. 4 STF 1604 ..Is indeed to many, the FRENCH FLAG COLOURS ..VIVA LA 1604!

Going.to have a crack at some of these again along with the Planets over this weekend..
ESP MARS SATURN AND M22 CONJUNCTIONS ON APRIL 1 AND 2..even the day before .
Weather here in Sydney has been very ORDINARY.
PS:SKYSAFARI ROCKS!
Cheers bigjoe
