Double Cluster - FSQ85 fight light


Recommended Posts

find the gorgeous Double Cluster in the constellation Perseus. It’s a wonderful sight to see on winter evenings, here in the Northern Hemisphere.
 
The Double Cluster consists of two open stars clusters, known as “H” and “Chi” Persei (also called NGC 884 and 869).
 
This is my first light using the Takahashi FSQ85 telescope

I like that very much.  Maybe ease off a little on the red and a touch more on the blue but that's just my personal taste.  I assume you are pleased with the Baby Q?

Hey Chris Yes very happy with the baby Q ( I look to see how it performs under good skies and with narrowband.  Really nicely built and also really light..  :)

Excellent.

How are you finding the QHY9s? any issues? i've been seriously thinking about this CCD but was wondering how you're finding it :)

Do it do it! I have no problems with it what so ever. Last night the obs was showing 24c, had the ccd cooled to -20 in mintes with a steady power of 32%

 

I use 36mm filters but 1.25 can cover it too

Hahahaha top man.

What i've heard is that the only problem seems to be when you try to shoot at a faster speed, like below 2 seconds, then the shadow casts from the mehcanical shutter starts to appear. Below 2 seconds mean you won't be able to (just saying) do planetary imaging or (which could be a pain) take simple flat frame.

THat is true but when I take my flats I use a EL panel. You can dim the brightness. I aim for around 23000adu and dim it enough so the exposure times are over 2 seconds 

 

my lumance is 1.6 seconds and you can see the shutter in the bottom right corner but that doesn't effect the overall image as you can see in the double cluster ;) 

 

as for planetary work I personally wouldn't use it but go for something like those celestron Skyris

That's excellent advice mate. 

I know i wouldn't use it for planetary either but just what someone said and i quoted :)

Mind if i PM you? don't want to hijack the thread and take the limelight away from this brilliant work :)

      The view from my centre of town garden is both physically & light-pollution restricted. Anything below 25 degrees is out of the question, anything West below 60 degrees behind bright buildings and a huge South-Easterly sycamore tree combines with a neighbour’s security & outdoor fairy-light obsession to make a fairly narrow observing window to say the least.
      The local park about 5 mins away potentially offers a darker & wider alternative which I confirmed this week on a late night dog comfort-break excursion.  All of a sudden, from a spot around the 22 on the rugby pitch, a break in the cloud  presented a full vista of Orion, Taurus, both Canis, Auriga, Gemini, Perseus & Cassiopeia- I was star-struck to the point where my furry companion thought I’d lost it. Messier clusters in Auriga I’d struggled to get in the eyepiece from the garden were immediately visible as naked-eye diamond-dust, the Pleiades sparkled and M42 glowed.  It was ten minutes of magic. 
      Inspired by my mid-week bonus I hatched a plan to head to the park the next time a clear-sky coincided with a non-school night.  Tonight promised a couple of clear hours around midnight but dodgy weather earlier in the evening combined with the feeling that lugging the Mak and tripod to the park might  be tough to justify as a lockdown exercise break, confined me to a late night stroll armed only with my trusty 10x50s. Having overcome the nagging sensation I might be mistaken for some kind of lurking pervert, I set off for the park.  
      In the end I got about 15 minutes  before fog bubbled up from the river. But even this fleeting glimpse allowed me to confirm I can now easily find the Messier clusters in Auriga and put my bins straight onto the double cluster in Perseus, things I’d never seen before lockdown.
      As the fog closed in I took a sweep of the alpha Perseii cluster and Pleiades, my current binocular greatest hits, and headed home happy.

      Also known as h and χ Persei, the Double Cluster (comprising NGC 869 and NGC 884) is a "line of sight" pairing in the constellation in Perseus, though actually they are only a few hundred light years apart. The clusters have a combined visual magnitude of 3.7 and 3.8 and are visible to the naked eye as a fuzzy patch between Perseus and Cassiopeia.
      NGC 869 (top) has a mass of 3700 solar masses and NGC 884 weighs in at 2800 solar masses; the total mass for the complex is estimated in excess of 20,000 solar masses when including an extensive halo of stars. Based on their individual stars, the clusters are relatively young, both 12.8 million years old, with the hottest stars having spectral class B0; NGC884 also has 5 prominent red supergiants including variable RS Per (closest to the centre of the lower cluster). North is to the left in this view.

      I took these images on Sat 25th Nov from here in W Oxfordshire. I've got the widefield setup running now using a RPi3 running KStars and Ekos. This controls a modded, uncooled 350d (with Baader filter) and a serial shutter cable, an Arduino motor focuser (as a Moonlite compatible focuser) and the Losmandy GM8 it all sits on.
      Images were taken through a Canon 85mm f1.8 EF lens at f4.5, exposures were 45 x 300sec (3h45m total) at ISO400 through an IDAS P2 filter. The field is a whisker over 15x10 degrees. Processing was in PixInsight and a bit of work in Photoshop to reduce a bit of amp glow that didn't calibrate out fully.
      Fairly pleased with this (though the Heart and Soul have come out maybe a little red - the colour calibration uses PI's PCC tool, and the IDAS filter might throw it a bit), but there's some other areas of interest coming through in the image. Annotated image attached but there are a few other bits that PI doesn't grab - there's a small area of reflection nebula (LBN 142.14+01.97) to the left of Sh2-202 that's just coming through. Also, unlabelled are Stock 2 (between the Heart and the Double Cluster) and for the interested clouded out astronomer, galaxies Maffei 1 and 2 are visible in frame just below the Heart (labelled as Sh2-191 and Sh2-197). 
      Thanks for taking a look!

      Astronomical twilight ends 6:18pm
      Transparency: 4/5 to 3/5 (above average to average)
      Seeing: 3/5 (average)
      Location: Fort Collins, CO
      Elevation: 4997 ft. (1523 m.)
      Bortle 6 to 7 skies depending upon which direction you're looking.
      The Double Cluster is pretty clear tonight. I can see it in my binoculars as well.
      M31 is very clear, and in the Binoculars as well.
      I then try and catch M8 which is just barely above the building down the hill from me. The time is 5:40pm MST. M8 gives up it’s nebulosity only using the LP filter I use. Orion UltraBlock Narrowband LP filter.
      I find M20, M21, M23, M10, M24 with my telescope (8SE) and then:
      At 6:15 pm, I go for M22, this is a new object for me. M22 is nice and clear, with good granularity, and some individual stars using the 17mm which gives me 119x. This is usually the best globular cluster eyepiece so i leave it in there for the next object. But before I do that, I decide I’m going to find M22 with the 10x50’s using my red dot star pointer. Note: The nice 9x50 RACI finder scope I’m thinking about will not be usable in this way like the crappy little star pointer does. A telrad would be nice I suppose and certainly it's clear why people like them. I'm just looking into making my 8SE non-GOTO (because I'm clearly a star hopper at heart and really want a 16 inch minimum travel dob from Hubble Optics). We shall see if i really even need to do that since I'm actually successfully using the 8SE to teach me the sky. Since I'm taking notes and all.
      I actually am able to find M22 with my cheap 10x50 bino’s. Fuzzy little ball but definitely there and visible to my binoculars.
      Next up: M55. It’s roughly 6:27pm MST and I continued through my list. M55 is a nice bright glob tonight. I get down and peer through the star pointer and gauge which section of sky I’m looking for and stand up, put the bino’s to my eyes and with very little searching I found M55!
      Next was M25, not sure I found that with my binos really.
      Then I was at M18, M17, M16 all three were lovely. It was roughly 6:48pm by then. Because I was mainly looking for nebulosity I didn’t try these three with the 10x50’s. I’m sure i should have.
      I catch a glimpse of M76 when I thought I was slewing to M16 in the prior group. I thought, what a waste of battery power. I looked at it briefly, and slewed back to the object on the list, M16.
      Next was M11 which I then found with my 10x50’s. A nice little dusting of stars in the binoculars!
      Following that was M13 which gave a particularly clear view this evening. I have been looking at star charts for quite a while now, and I have something of a photographic memory (comes in handy during band practice!). So I used the star pointer to give me the section of sky. This section of sky is really hard to look at and not loose your dark adaptation. I use an eyepatch and a black t-shirt pulled over my head backwards as a hood to keep stray ground light out. But trying to find something in the sky and star hop to M13 seems really not doable to me. However, the star pointer does show me where M13 is and I find it easily between Eta and Zeta Herculis. Just southwest? Of Eta Herculis.
      Now, this is the cool part. Because I’ve looked so often at the Hercules constellation, I had a good idea that you just went back to Eta and then you could find M92 between Eta and Iota Herculis. Slightly more than halfway.
      And there it is, a short star hop after finding M13, I find M92 without the telescope helping me. From a star chart in my memory. Awesome.
      Emboldened by this additional object added to my list of things I’ve seen with my 10x50 binos, I went back to Cassiopeia and hunted around there using the 10x50's to look for NGC 663 and NGC 7789. I definitely see NGC 663. I find M45, Hyades, Aldebaran, I use Delta and Gamma Cas to point me towards NGC 884 and NGC 869 aka the Double Cluster. As always, it is beautiful to see. I really like the 10x50’s. Really looking forward to the 20x80’s I’m getting next.
      Next I aimed my 8SE towards M57. I tried to see that with my 10x50’s but couldn’t. I thought I did but couldn’t confirm it.
      About 7:30pm MST I slewed over to M56. This is a nice Globular. Bright, granularity, some individual stars. Very nice. I go for this one in the bino’s and there it is!
      At 7:39 or so, M27 was up in the 8SE and i tried for that with the 10x50’s and I do believe I found that as well!
      M71 right after that, and yes, I did in fact use the 10x50’s on this object and found it as well. From M71 I found the Coathanger Cluster. So there are a couple new, easy to find (i think) objects M27 and M71 between Deneb and Altair just south of the coathanger cluster. I’m sure I can do better at star hopping but this is a lot of fun making my 8SE actually teach me something.
      M29, the cooling tower, very nice in the scope, very not found in the bino’s. I’ve been looking for this object in the binos for a while. It’s pretty easy to know where it is, there all close to Deneb and all. It being just south and above of Gamma Cygni. But seeing the cooling tower in the 10x50’s might be impossible. Maybe the 20x80’s.
      I went on to M15 around 7:43 pm MST. Very bright! Wow, this is amazingly bright! I handily found this in my binos as well!.
      M2, M73, M72 all found first by the 8SE and then by star pointer to my binos.
      Right at 8:00 pm MST I saw M30 on the list. I know this is a new object. So my crazy memory tells me. So i slew to M30 and gaze upon its beauty for many minutes in the 8SE. I find it easily in my binos with the help of my telescope.
      Last couple objects on the list:
      M77 - 8:09 pm MST this is only visible by slewing the telescope and introducing motion. I did not find it with the 10x50’s.
      M76, which was given a glimpse earlier was not findable by my lazy, about to call it a night, eye.
      The temperature was 36 degrees and my hands were beginning to hurt from the cold a bit. The thought of going inside and playing guitar instead of freezing in the somewhat stout wind (6 or 7 miles per hour) is probably why I couldn’t find the little dumbbell nebula.
      I see one object on my list from that night I skipped. M34. It keeps getting on the list then falling off at the last minute… it’s still early in the season for that object though. Although I didn’t even stay out long enough to see Orion coming up (over the tree).
      I thought to myself, as I packed things up around 8:20pm MST, that was a pretty short session. But it was action packed with lots of new bino objects found!
      Tonight (11-14-17) the transparency is “transparent” it is supposed to be cloud free but the seeing is bad (1/5) to poor (2/5) and 20 mile an hour winds. So no star gazing with anything but Binoculars in a parka on a zero gravity chair for me tonight.
      I'll let you know how many of those new targets I can see tonight. Pretty sure I’ll be able to find M13 and M92. M27 and M71 will be trickier But I think I can find M30 again.
      I'm going outside to try in a few minutes here after I post this.

      This started on 10/31/17
      I had set my 8SE up at around 7:00 pm
      Transparency: above average 4/5
      Seeing: average 3/5
      I viewed a number of objects with my 8SE:
      M31, M32,
      M110 was not able to see.

      M57, M27 are always available.

      M13, M92 sitting very pretty in a clearer patch of sky than usual to the west.
      I was early enough to catch some favorites, M8, M16, M17, M20, M21, M22, M23, and M24

      I then took a break and when I came back I grabbed my binoculars, 10x50's.
      First I viewed Pleiades, then Hyades, then over to Mirach, Nu, Mu, and above that to M31. I couldn't see M110 or M32 in binos.
      I've been searching for Kembles Cascade with binoculars, which I've found with the 8SE, though you can only see two stars at a time at that magnification and narrower FOV.

      So I'm looking around the general vicinity below Cassiopeia, in Camelopardalis and eventually wander into Perseus and find:
      The Double Cluster with my binos.

      I slewed the 8SE over to NGC 884, and NGC 869 to confirmed that I had in fact found the double cluster in my 10x50's
      I finished my bino tour of the sky on the Coathanger Cluster.

      I have never viewed the Coathanger cluster through my telescope. Well, maybe once just like M45 and Hyades. I always use binoculars to look at these objects now.
      I finished the evening on M42 which I end up looking at for nearly an hour through both the binoculars and my 8SE
