Needle and M13

Ebay has finally yielded some new tougher bolts and replacement battery for my mount so I couldn’t resist the lure of some clear skies on Sunday night. Given that it was a school night and it didn’t get dark enough until after 11, I thought I’d try and do it Roger-style with shorter exposures on my little ZWO camera (sadly I didn’t have any double glazing facing the right way for this).

As well as borrowing Roger’s approach I also borrowed one of his recent targets as I’m quite taken by the Needle Galaxy at the minute, along with M13.

Needle is a stack of 35x 20 second exposures. I had gain at 500 for this and it was very noisy and I had to process it to within an inch of it’s life to get something out of it.

M13 is a stack of 80x 7 second exposures- the same gain, but the shorter exposure/more subs seemed to help, and in comparison it fell out of the camera and processed itself (OK- I exaggerate).

Started imaging at 11:15 and done and dusted and in bed an hour later! Hopefully will get another go at this on a darker night and with more time to play…

Devil’s light bulb vs iPhone.

Not a fan of either , but very surprised to get startling crystal views. Took over x200, some cracking details and fun to observe . This 35 year old Vixen 102 f10 punches above its weight as a classic achromatic.

So good that I put the phone over the eyepiece and took a few snaps. I have a digital cam holder somewhere. Seems strange that small eye relief eyepieces give results ,against bigger and longer eye relief ones, under ,

clear skies ! Nick.

The best of Ophiuchus.

Ophiuchus (” serpent bearer”) is below Hercules, it divides Serpens into two halves, heading for the galactic centre here. A realm of globular clusters, some 22 , most are detailed here. Some surprising other deep sky targets as well.

Globular clusters.
M9 – to the galactic centre, M10, M12, M14,M19,M62,M107, NGC 6273 (+6.7) , NGC 6304 (+8.2),NGC 6316(+8.4),NGC 6333(+7.7),NGC 6356(+8.2),NGC 6355(+9),NGC 6402 (70 variables here)(+7.6),NGC 6401(+9.4),NGC 6325(+10.3),NGC 6293(+8.2).

Open clusters.
IC 4665 (“summer Beehive”), stunning large cluster, unusually this is 15 degrees off the galactic plane.
NGC 6633 .

Planetary nebulae
NGC 6369 (“little ghost” +11.5),NGC 6572 (+8.0) the stunning very blue and bright “blue racquetball”), central star visible as a glow, NGC 6309 (+11.5) “box nebula”, NGC 6366 (+9.2).

Individual stars
Carbon star , V (SAO 159916) from +8-+9.4.
Barnard’s star, second nearest star to us, with an astounding 10.3″ proper motion per annum.

Binaries
Marfik (λ) 1.6″ separates this bright pair (SAO 121658)
Rho (ρ) a group of companions, nearest at 2.9″(SAO 184381)
Σ 2048 dusky companion at 5.6″ at 16h28.8m. -08 08′
61 Ophiuchi , bright pair at 20.6″ (SAO 122690)
69 Ophiuchi,(τ), challenging 1.5″ (SAO 142050)
Σ 2276 twins at 6.9″ (SAO 103373).

A packed constellation, the most stunning view being the very bright “blue racquetball”, a summer showpiece, under clear skies ! Nick.

A Day’s Observing from Streethay 19/5/2018 – The Royal Wedding…

The ‘big day‘… and the weather couldn’t have been better… sunny for most of the day plus into the evening forecast (although there appeared to be a layer of high cloud).

There was great excitement in the Briden household to see what our guest would appear in… would it be a one or two piece, perhaps sandals… or a hat.. or come completely ill-prepared…

Look who came around to play, after arriving in her (motorised) carriage !

Yes, well ‘Meghan‘ is a bit shy after all… and these solar hoods/veils can be a right pain to get into!

And a pic of ‘her’ using her own scope and trying a different… veil…

Our solar panels had a cracking day also – generating over 24kWh.

To get into the spirit of things Julie appeared with flags…

What a fine specimen of a man is our ‘Harry‘… It was a first chance for him to use his updated home-made sun shield – now faced with white card to reflect some heat and so stop the main cardboard construction warping (the other face is covered with DC-fix black self adhesive felt – the same stuff that ‘Harry’ had lined his 10″ OO Dob some years ago…)

Although the seeing was not so good today, one has to make do when the opportunity arises… besides it didn’t spoil the generally good feel of the day… we even managed a celebratory glass of Pimms No.1 no less – I say, can’t get more British than that!

Following two images are taken hand held, iPhone6 to a 32mm TV Plossl, (Takahashi TSA102s, Daystar Quark Chromosphere, 2″ Baader UV/IR blocking filter inserted before the diagonal), running at 107x

…showing a fantastic set of ‘Newton’s (wedding) Rings‘ there!

This prominence can be seen on the GONG images at the 8 o’clock position…

My sketches of the evolving prominences throughout the ‘big’ day…

After a great day, we retired for dinner, then set up again with changed attire…. ready for the…. ‘evening event‘!

What a beauty, hey! Just checking how he looks on the ole social media! Here featured in a RAG jacket, matching trousers and footwear by….

Lunar shot taken at 9.50pm, iPhone 6 hand held to the 21mm TV Ethos (TEC 140-ED APO refractor)

..and another slightly later at 10.05pm (not so zoomed in) – those damn paparazzi, hey….

Had a chance to do some drawing…. managed quick sketches of both the Western and Eastern (Bridal) Veil portions. Seeing and transparencey was not good and my intended target, Jupiter, was just not great tonight to bother with…

Managed to just pick out the Crescent Nebula in Cygnus (only via my 2″ Lumicon OIII and UHC filters), but I’ve seen it through the same scope much clearer on a previous occasion.

Most tricky observation came early on in the evening after following Andy… sorry ‘Meghan’ to M81/M82… came across ‘Coddington Nebula’ in the same vicinity – IC2574, a spiral galaxy in Ursa Major, running at Mag 10.4. Took averted vision, patience and the superb Sky Safari Pro 5 charts (able to reverse the chart as well which really helps to double check everything). Discovered by Edwin Coddington in 1898 and classified first as a ‘nebula’.

Best observation was the ISS flypast just after half 12. Was able to use the laser pointer attached to the Nova Hitch mount to track it sufficiently well for brief periods to see the Space Station as clear as day through the eyepiece as it whizzed passed the ‘adoring throngs‘!

So to wrap up this post, a few pictures of the ‘Happy Couple‘ in the garden at Briden Palace!

Sweet…

…off on ‘honeymoon’ to RAG this Friday!

Damian (and Andy!)

 

Observing Log Streethay 19/5/2018 @ 22:00 -20/5/2018 @ 03:30

Damian and I spent a memorable evening outside last night. Not the best of skies. However with the help of his Tec 140 on his Nova Hitch and my Sky Watcher Equinox Pro 120mm on my HEQ5 Pro Synscan mount, we observed a wide range of objects including Moon, the Eastern Veil Nebula and Witches Broom part of the Veil (both of those required an OIII filter or UHC to view well & were virtually invisible without such a filter), Ring Nebula, multiple other planetary nebula, globular clusters galore, Jupiter (the tracking Synscan HEQ5 Pro really helped here allowing me to get Jupiter in the field of view and keep it there at 600x magnification – 6mm Ethos + 2 x Tele Vue Big Barlow + 2 x Tele Vue 1.25 inch Barlow! – where we saw a wealth of detail on the planetary belts, open clusters and a lot beside.

I “upgraded” to Sky Safari Pro 6 planetarium software on my iPad a few months ago when there was half price deal and it turns out that it is very difficult in this new version to e-mail our observations to myself so that I can upload them to this blog unless they are set up on the software correctly first under an observing list which I did not do last night – plus the software keeps crashing on me whilst I try to get them off the machine – my old iPad is the problem here. So, I will downgrade my version of Sky Safari software on my iPad back to version 4 or 5 which worked well on this iPad and where observations were easy to get off the machine. Thankfully, although I could not buy those older versions now, it turns out they are still available in the iTunes store under “My Purchases” as I previously purchased them…..so they are both downloading now!
