Hunting Virgo Fuzzies I

Date: May 7th 2010 Friday
Observation Time: 8:00pm to 11:30pm (3.5hrs),
Location: Jon's Home, Boulevard, CA
Weather: Lil clouds on western horizon. Transperancy okay.. no wind..
Instruments: Jon's 16" dob, NP101 APO, AT102ED
Buddies: Jon

Friday evening drive after work.. was definitely worth because of virgo fuzzies..

- Venus: Checked the APO ED lateral colors in AT102ED and NP101. with focused image, no colrrs in any APO. With out of focus venus, the AT shows the lateral color, while NP just doesn't show anything.. does it bother? nope :).. I iwsh Celestron refractor would haven been.. it would have showed heavy color with focused image itself.

Porrima: Split very very hard hard for me. 396x in Jon's scope..
Castor: Split failed.

- Izar - don't remember..

- Eskimo Nebula.. bluish nebula.. need to get familiar with the location, before it goes away..

- Double planetory - way too faint and tiny in Jon's scope itself.

Browsing thru finder without using red-dot or telerad was lil hard.. is using telerad consdered to be cheating :)? Finder is not focused either. Need to get comfortable with the view in the finder.. right angled finder helps..

- M35 - faint and tiny image in my M35. Need to watch out for the size of the object in low magnifications.

- Saturn - ???

M95-96-k-leo: Quic browsing thru K-leo gals..

Coma 4565 and the irregular one.. moteling ??

M3: GC
M53: GC
NGC GC next to M53: Really faint and dispersed. Hard to tell if its a faint open cluster or the GC itself. How do they identify it ?

- M63 Sunflower galaxy: Elliptical. Easy to catch. CVn visible cluster. M63-M51 and Alkaid Seventh UMa forms a line.

- M51 whirlpool: Spiral feel. Spiral arms. NGC object on the right arm of M51

- M94 in CVn: Easy to spot..


- Black eye galaxy missed..

Dark night kickoff in freezing cold - II

Continued..

Eskimo nebula: The middle star jumps right at you.. if seeing is better, probably can see more details. bluish disk..very bright in the center and fainter outside..

Double planetary - In Jon's 28mm UWAN ~75x, way too tiny to see this one..but definitely you can see it. The clear 8 shape visible.

M81-M82: location. I always miss the location of this one. Pick up first and 3rd star in square of UMa and draw the digonal line that points to 2-3 star cluster, just below SW of it is M81 and M82. You can defintely see the pattern/texture on the edge galaxy. The pair is clearly visible thru binocs, once you know the location.

M51 Whirlpool galaxy: Not the greatest view of whirlpool. bad seeing..

M next to the third UMa star (seems M109): in jon's 28mm UWAN, 3rd UMA star and M?? (M109) is visble in the same FoV.

M36-37-38: binocular browsing.. Jon mentioned about some ngc next to M37??

Leo triplet M65-66-3628: Jon pointed to it. 3628 fainter than other two. All 3 in same view (with uwan 28 75x ??). 3628 elongated and bigger in length than others ??

Jon's galaxy pair in UMA: Two faint galaxies in the view. If you continue the tail of UMa, same distance as 5th & 7th star along the tail. (UPDATE 03/10/2011: From the location, seems to be Hickson 68 in CVn)

M3: Jon pointed the location.. bit tricky.. visible thru binocs.. Outskirt stars are clearly resolvable. higher mag helps..

Sombrero Galaxy: Jon pointed the location.. lil tiny than what i was expecting. elongated.. but no sombrero structure visible.

Friday KC Dark Night - I

Date: April 17th 2009, Friday
Observation Time: 7:00pm to 1:30pm (6:30 hrs)
Location: KC, CA
Weather: Weather is okay.. Transparency is good, but seeing is not good.. lil bit wind and it increased every now and then.. wind was pretty bad at 10pm as well as 1:30am.
Instruments: Orion XTi 10, Jon's 16.5' and Jon's 15mm, 24mm TV widefield EPs and WO 28mm UWAN EP.
Buddies: Jon

New Objects: 12 + Markarins chain

Rigel (New): Nice Double. wasn't aware that its double.. don't remember details..

Gamma Leonis: Yellowish pair.. easy split.

Saturn: Seeing is okay.. not great image.. surpringly for whole night, never visited it again.. seeing was also bad..

M36: Comet Cardinal (New): M36 Y cluster. Tried to locate Cardinal just next to it.. but i guess it wasn't dark enough so didn't find it.

Lambda Orionis: Mriga Shirsha: Multiple stars, but one of them is double..

M79 in Lupus: Again not dark enough, so took a while to find this GC. Preety low on horizon. Faint fuzziness visible, hard to resolve any stars at high mag also.

Beta Monoceris (New): Impressive Triplet. all white. With 38x, only a pair, wide enough.. but at higher mag 76x, you can see one of the star itself is a double and preety tight.

Castor: Bright castor with really faint red companion. Really wide double, easy to split in 38x also.

Gemini Planetary Double: Jon showed it to me last time and locating this one failed from MTRP. Found it with help of Jon again and confirmed the location.. barely visible in 38x..

Comet Lulin: Visible in Jon's 16.5" scope... really faint, but still visible.. mag 11.. Tried comet Cardinal again.. failed..

M35: Impressive Cluster. You can see the bright curved line inside the cluster. NGC was on the SW of the cluster. Wanted to confirm the NGC w.r.t the curve line.. Its in the same line as the curved line inside M35.. but located way outside M35. should be able to find NGC from MTRP.. but its indeed faint. At the other end of the curved line, there seems ot be a double star.

Also tried Jon's TV 15mm Wide Field eyepiece (80x). It definitely has higher FOV than my 32mm x 2x barlow.. It fits whole M35 as well as part of NGC.. but mine doesn't fit both at all. the eyepiece is defintely better than mine, but eye relief seemed to be lil bit low. Need to read more abt this eyepiece specs (??)

Tau CMa: Along with Jon's 15mm TV, tried 24mm TV wide field. Again 24mm, has better FOV than my 25mm Elux, but as far as performance concerned, my 25mm gives good image too.. wasn't able to differentiate them..

but overall, 15mm TV eyepiece was better than 24mm TV.

MTRP - Calle De Vida

Date: Apr 12th 2009, Sunday
Observation Time: 8pm to 9:45pm (1:45 hrs)
Location: MTRP, CA
Weather: Okay.. Seeing 4 of 5. Transparency 3 of 5.
Instruments: XTi 10.

MTRP Clairemont Mesa entrance is closed now. So entered thru another entrance Calle De Vida, 2 blocks from original entrance.

Alcor-Mizar: Started with double. At 38x itself, clean split of all MizarA-B. All three white in color. Had hard time determining position angle.

Gamma Leonois: At 38x hard to split, 76x was hinting of a split, but 120x was better... really close.. Yellowish pair.

Regulus: document says its double, but is it? there is a faint star in the vicinty, seems to be optical double.

Orion M42: Okay.. Disk visible. M43 was sort of fuzzy. Trapezium E-F not resolvable at all.

Flame nebula: Failed. Just no nebulosity at all..

M78: Location was perfect, as mentioned from last observation. barely visible though.. faint.

Castor (New): Really close double. 120x is the first one to split.. really close.. higher mags help.. again white pair..

Gem Double Planetary: Jon has shown me thos one multiple times, but i didn't know precise location neither how it looks in finder. Atleast at 38x really hard to see anything. Its one of those objects that need higher mags and precise location. FAILED.

M35 OC: Impressive... The curved line inside the cluster.. didn;t find the NGC OC just otside it. Need to remember the relative position of it wrt the curved line.

Pollux (New): Not a double, but nice yellow-orangish star. Nice contrast betn Castor and Pollux.

M65-66 Triplet: Really too faint. Found it easily. but M65 and M66 were visible. NGC was sort of averted vision, giving a hint of it.. but wasn't sure.. Overall the M65-66 pair was so faint that wasn't worth increasing the magnification.

M81-82: thought that had it in the view, but didn't.. just too faint to see anything.. Last time, caught it without any trouble, but this time had hell lot of trouble in star hopping. nedd to learn abt background stars. Dark night makes thing simpler :)

Saturn: Spent lot of time on this one. Tested Jon's planetary eyepieces TMB 4mm and 6mm on this one. Went all the way to 2mm using barlow. Somehow seeing/scope was stable. Saturn was marvelous, in-and-out focus, in 3mm (400x) itself and I had breathtaking view. Surprisingly with 600x, it wasn't sharp at all, but still disk was huge and gap between disk & rings was clearly visible.

M3 GC: Naked eye Star hopping session required. hopefully next time i will remember it. Finder shows it clearly. At 38x its fuzzy, At 76x Outskirts is resolvable. At110x few star in front of the core are resolvable. 200x didn't make much difference.

M53 GC: Easy. Next to Aplha-Com. Finder barely sees it. 38x, 76x shows it as fuzzy, but 110x resolves couple of bright stars at outskirts.

Messier Marathon - Part II

Continued..

NGC 2467 nebula (New): while looking for M93, ended up at this one. M93 is on one side of Xi pup, while this is exactly opposite side, same distance. good looking.

M93, M50 and M48 OC: From Light polluted skies, these guys are prominent, but from dark skies, not impressive. :)..

Overall, during whole night star hopping, while looking for intended objects, I saw so many fuzzies on the way that its hard to keep track. I tried my best to look into star atlas, before moving on.

Also M93/M103 examples show that my sense of direction within inverted image of reflector still messes up sometimes. Have to get a better judgement.

Comet Lulin: In Gemini. In 16.5'. Around mag 9. Fuzziness is still visible easily, but small.

Gemini Double Planetory (New): In 16.5', Marvellous pair of planetory. sort of 8 shape visible. Magnification helps. Don't know the location (TBD ??)

M1 Crab: Watched after long time. Easy catch.. Again directional sense in eyepiece messed up. Mag helps.

M36-M38-M37 OC: M36 and 38 are inside, while M37 is outside pentagon. 36 is smaller than its brothers. It has inverted Y shape or stick figure tree shape. M38 is impressive with Pi shape, while M37 is probabaly same size as M38 and it has like ice-cream cone shape, with ice-cream on top :)..

M35 OC: This is another impressive object. At lower mags it fills the eyepiece. All bright stars. The best part is that it is acommpanied by a fuzzy object next to it. It seems to be a nebulous object, but somehow star atlas says its a open cluster. If thats the case, it must be really tight, concentrated and star rich cluster. higher mags seem to be resolving more stars in this one. Need to read more (TBD ??)

M44 OC: Beehive was naked eye.

M67 OC: Star atlas helps to point it betn M44 and Hidra head. It is arched H shape. Left arc of H shape is full of stars. Impressive view.

I am glad i noted my observations on paper during the session. Otherwise i would have got confused between so many OCs.

It marked end of first leg in my marathon. Almost all objects from West side are done. Bit tired by now.. Almost 10:30pm !!

Saturn: Okay seeing/ At 220x, image was fine not that stable. shadow of rings visible clearly on the disk.

M95-M96-M105 plus nearby NGcs: Easy catch. All of them visible. Quick glimpse.

M65-M66-NGC3628: Forgot the location.Took few mins. All them visible. 3628 wasn't clearly visible. Quick glimpse.

NGC2903 Galaxy: Read abt this, but never seen it. Easy catch. Well positioned. Almost edge-on.. bright.. Need to spend more time on this..

NGC 3226-3227 Galaxy pair (New): Jon pointed to this one instead of 2903. Its close to Gamma-Leonois. Pair is bright.. (TBD ??)

Planetory Nebula in Corvus (New): Fought for it so much from home, and from dark sight its easy catch. Too faint for home observation, if don't know where it is. Yet another fuzzy, but didn;t look like PN. Pattern visible thru jon's 16.5'

Antenna galaxies (New): Asked Jon to show me this one. Fought for it from home. Too faint in 16.5' also. Hard to see any pattern. Hopeless pair..
