IC410 Tadpoles - first light for Takahashi FSQ-85

Recommended Posts

I was very excited to get a couple of hours of clearish skies last night to get first light with my Takahashi FSQ-85.

It turned out to be something of a comedy session, however.

Firstly, being a cheapskate I hadn't bought the Takahashi clamshell and opted instead for some 95mm tube rings. Trouble was, mounted to a fairly short dovetail I wasn't able to balance the scope properly; it's no biggy but I need a longer dovetail and to raise the rings slightly so that the dovetail clears the focuser...

Secondly, my dew strip packed up for some reason. Not sure what's wrong with it or if it can be salvaged, but the wires feeding the strip were getting plenty warm, but the strip itself wasn't. It's barely been used so not sure what to make of it... Anyway, it meant the optics had slight misting for the latter subs. I am hoping that this explains the halo around 19 Auriga in the top left.

The final thing was pure stupidity though. I somehow managed to turn off the TEC on my CCD camera so the subs were at ambient temperature and therefore very noisy (in comparison). Combined with high whispy cloud this can't be seen as any kind of test for the new scope. In any case, I expect it to come in to its own dealing with blues... so we'll see.

Anyhow 10 x 600 sec subs Baader Ha filter.

Mount: CG-5; Scope: Takahashi FSQ-85; Imaging cam: Atik 460ex; Guiding: PHD & IMG0H.

Nice work despite all issues,

Should look great with some colour added.

What a fab scope - You are very lucky!!! Processing wise, this has been over cooked - the tadpoles have been over stretched and also a part of IC410 above them.

Thanks Martin, Fay, Jake, Mark, Sarah, and Gina for your comments.

Sarah - I'm led to believe it's a fab scope, but it'll be some time before I am able to prove it! I'll be really interested to see if I can detect a tangible increase in performance over my TS triplet which I have to say I have been very impressed with... Don't get me wrong - I am sure the Tak is a better scope but I'm still a beginner really... Thanks for your thoughts on processing. I wasn't paying too much attention really: just a quick combine in AA5 (and I had to use a sigma combine because of the noise which isn't my preference) and a quick and dirty stretch in PhotoPlus. It looks okay on my laptop screen but I am sure you're right...

Anyway, thanks again for all the comments. I really want to get a good capture of this one. Not sure these subs will make the final cut as the guiding graph was a tad alpine thanks to the scope balance I suspect... but I learn something every time. Wish we had more clear skies!

I too will be very interested to see if over time you can detect an increase in performance with the Tak. I will watch with interest :smiley:

      During the “close season” I decided to upgrade the camera and peripherals on my venerable Vixen ED114SS.  Whilst the scope itself has some minor faults, I am rather attached to it and decided I could live with the slightly halated stars at the blue end of the spectrum, and reckoned that the addition of a focus motor might help reduce the considerable image shift I was getting when trying to manually tweak the rather hefty rack and pinion focuser after swapping between filters.
      The first stage was replacing my old and equally venerable SXV-H9 for a wider field camera with set-point cooling.  I had ruled out shuttered cameras and big chip jobs, partly on cost, partly because I wanted to stick with my existing 1.25 inch Astronomik LRGB filters, and partly because I wasn’t too sure the ED114 could give me a flat field over too big an imaging area (although DLSR frames had always seemed reasonable). 
      After much agonising I went for the ATIK 460EX, rather than the Starlight Xpress equivalent, the SX674.  My SXV-H9 has been absolutely brilliant for the last 15 years and the SX674 (with its excellent cooling capability and nifty inbuilt USB hub) was therefore very tempting.  What put me off was that I have never had much luck when it comes to Starlight Xpress software.  I have yet to successfully install the SXV-H9 on any of the computers I have owned over the years first time, without an endless series of error messages and “missing driver” warnings every time I changed computer.  I had a similar nightmare when I bought a Lodestar last year.  Although I cannot fault the support I got from SX’s Terry Platt, who helped me get it all going in the end on my obbo PC (though even he couldn't make the Lodestar work on either my XP laptop or desktop), I would rather just have something that works out of the box first time, without the need for a subsequent series of e-mails and additional software downloads. 
      My old ATIK manual filter wheel was also overdue for replacement.  This has always leaked light and I had to resort to wrapping it up in tin foil, like the turkey it was.  The act of manually changing over filters also seemed to cause a tiny bit more image shift. 
      As I had plumped for the ATIK 460, I thought I may as well push the boat out and get the EFW2 electronic filter wheel to go with it.  And a new set of narrow band filters while I was at it.  My existing H alpha filter was a 12nm bandwidth, and my Astronomik OIII filter was utterly useless for imaging, giving horrendous halos around stars.  As the EFW2 is a nine-place job, I also went for a full stack of Baader narrow band filters (SII, Ha, OIII and Hb), which, when combined with my LRGBs and a CLS, filled it up nicely.  I have never used SII or Hb filters and it will be interesting to see what they add.
      So eventually, I gave many, many of my pounds to local astro dealer Ian King who, in return, promptly sent me my shiny new toys. 
      It was with some trepidation that I downloaded ATIK’s software on to my observatory Windows 7 PC.  It took a nerve-wracking few minutes for it all to squirt over the airwaves and down the wires, hanging for disconcertingly long periods during which it seemed to be doing nothing.
      And then finally…
      …it all connected and it all worked, first time.  It was the same story when I loaded it all on to an old Vista laptop.  No drama, no fuss.  I was a little disappointed that I couldn’t get the camera to talk to Astroart, which I had been using for image acquisition, despite downloading and installing the Astroart plug-in.  However, ATIK’s Artemis capture software seems to be, in many respects, a better way of working and I soon got used to it.
      The EFW2 is a beast of a unit.  It is very solidly built and makes a satisfying little hum to let you know it is doing its thing when you ask it to.  Its size meant it needed to be mounted “upwards” on the back of the scope to avoid hitting the telescope pier when the scope was pointing at targets overhead.  Fitting the filters is easy, and having nine places makes that a one-off job.

      With the image train sorted, I decided to look at the focuser.  I also now had a veritable rat’s nest of USB, power and dew heater cables hanging down from the scope that meant a snagging disaster would be inevitable.  Whilst I was wary of introducing a USB hub into the mix given the many and varied horror stories I have read about them on this forum, I thought a hub would be preferable to the alternative of four five meter USB cables (mount, filter wheel, camera, guide camera) and a similar run of 12v power cables trailing from the scope, down the pillar and along the floor to the PC/power supply, the former of which was already USB’d-up with the dome controller, keyboard, mouse and radio dongle for the internet connection.
      So yet more of my pounds went to Altair Astro for a Pegasus Ultimate Hub and associated focus stepper motor.  The hub mounted easily to a dovetail bar on the top of the scope and a set of quality Lindy 1m USB cable connected everything up, with a single 5m Lindy going back to the PC.  As a bonus, the Pegasus hub allows you to plug in and control your dew heaters (one for the main scope and one for the guide scope), saving yet another run of cables.
      I had a few minor niggles with the Pegasus kit.
      The mounting brackets are optional and rather expensive extra for what they are.  For the price they charge for the hub, you’d think they’d include them.  Similarly, they provide a nice diagram telling you how to wire up a cable for the focus motor (which I did), but I’d much rather they just supply the cable!  Maybe I am being unreasonable as I suppose some users will not require either.
      The hub comes with a full set of 12v supply cables which fitted the ATIK camera and filter wheel, but the input 1.8m 12v cable with a 2.5mm pin (the outputs are 2.1mm) isn’t really long enough.  I couldn’t find a suitable plug on the web to make up my own power lead, and so I just cut the cigar lighter plug off of the supplied lead and extended it (my power supply output is fused so no worries there).  Given that everything runs off this one input, I was a bit disappointed that it’s just a push-fit plug with no locking screw collar.  Other than that, the hub build quality feels excellent, with (all six) USB and (all four) 12v power outlet sockets firmly gripping their respective plug-ins.
      The focus motor comes with a somewhat bendy bracket that nevertheless fitted readily onto the end of the scope dovetail bar and enabled a straightforward coupling of the motor to the shaft of the rack and pinion of my scope.  I had to drill the flexible aluminium coupling boss out a bit as it was too small for my focuser, but other than that, it was a cinch to install.

      The control software for the hub downloaded and installed easily.  I would have appreciated some detailed instructions for using it, although to be fair it is fairly basic in nature.  I had an initial puzzling couple of minutes before I realised that the “connect” icon for the hub is a tiny squiggle tucked away in the top left hand corner of the main control screen.  Once I worked that out, everything connected up just fine. 
      Although my scope rack and pinion is a direct drive with no geared reduction, the Pegasus focuser allows really tiny adjustments to be made.  There seems to be a capability to manually put a backlash figure in to compensate for the inevitable lag in the rack and pinion, but it doesn’t seem to store the figure.  I guess the design intent is for it to run with an autofocus set-up, but I have still found it quite easy to use in “manumatic” mode, in conjunction with the ATIK Artemis focus screen.  It has greatly reduced the amount of image shift I get on refocusing, and allows me to make much finer focus adjustments than I could ever achieve manually.
      One outstanding minor aggravation is that the Pegasus software seems to “hog” the USB ports on my PC.  I have not (yet) routed my NEQ6 EQDIR USB connection via the hub, preferring at the moment to send that back to the PC separately.
      However, if I turn on the mount before I try and connect the hub via its command screen, the hub sulks and simply refuses to connect.  It connects just fine if the mount power is off, and then stays connected when the mount is turned on.  However, the hub seems to then “block” the EQDIR connection to EQASCOM from the mount.  The EQDIR connection shows up on the PC device manager, but I get the dreaded ASCOM “time out screen” when I try to run the planetarium programme.  I have to then unplug the EQDIR cable from the PC and then plug it back it in.  This seems to “force” the connection, and I can then open the EQMOD telescope control and connect my planetarium software to it.
      I now also need to make sure I connect the guide camera and mount to PHD before I connect to the planetarium software, otherwise connecting PHD after I have pointed the scope freezes the EQMOD control, stops all tracking and locks up the planetarium software, requiring a re-set from the Windows task manager.
      I’m not yet entirely sure that this is 100% down to the Pegasus software, but I had none of this aggravation before using the Pegasus hub.  I do wonder if my EQDIR cable is on the blink instead, but provided I start everything up in the right order, it all seems to work – touch wood.
      I may try and send the EQDIR output from the mount through the hub to see if this improves connectivity, but at the moment I’m inclined to leave things alone.
      The Pegasus hub offers temperature and humidity monitoring that has already proved invaluable as I live by a river, so that even inside an observatory, dew heaters are an absolute essential to keep the optics clear and dew-free.  There is an automatic option that allegedly adjusts the power sent to the dew heaters based on the temperature/humidity readings, but so far, it just seems to be full on/full off from what I’ve seen - not that this is a problem or necessarily even wrong.  It definitely runs the heaters once the dew point catches up with the temperature, so that's one less thing to think about.
      As for the ATIK 460EX, initial images seem very promising.  Although its cooling capability is a bit pathetic to be honest, running it at -5 degrees seems to give quieter and far more reproducible dark frame stacks than I could achieve with the SXV-H9.  And the image field offers twice the area, which I look forward to exploiting in the coming months.
      Although I am fairly pleased with them, my first images with the new set-up do show slightly eggy stars at the corners, with the axes of the eggs directed towards the centre of the frame.  This is almost certainly a camera spacing issue.  I have e-mailed Vixen UK to see if they know what the right corrector-to-focal plane distance for the ED114 is, but it may well be a case of trial and error to fix things on that front.
      One small thing with the EFW2 software is that although the filter wheel connects and goes through its initial start-up rotation as soon as I power it up via the Pegasus hub, attempting to subsequently select a filter position gives you a choice of a hundred filter positions, none of which work!  Disconnecting and reconnecting via the Artemis software brings up the usual nine positions, and the wheel works fine after that.
      So whilst not a clean win on the software front, I am reasonably happy with the upgrade exercise as it stands.  The ATIK camera and filter wheel work well and the Artemis control software seems hassle free and reasonably intuitive.  The Pegasus hub really cuts out the cable tangle, allowing me to easily de-mount the whole scope/hardware bundle and bring it all indoors for security purposes if I know I won’t be imaging for a while.  And I'm pleased with the simplicity of the stepper motor focus control and the delicate touch it provides.
      Early days I know, but the hardware all seems to work fine.  I think the software is going to be the immediate ongoing issue (as ever) but fingers crossed…

      I picked up an older CG-5 mount and tripod the other day for $50. It's in good shape, just a bit dirty. The Dec axis moves freely with the clutch loosened, and drives very smoothly with the clutch tight. The RA axis drives very smoothly with the clutch tightened (bear in mind this is a totally manual mount), but is stiff to move with the clutch loosened, and has a couple of spots where it is very slightly "notchy" when it is turned. How can I loosen this up, to make hand-skewing to a target easier? It has no polar scope, no big deal, and has provisions to add tracking motors, but I doubt I'll do that. I bought it to have a simple, grab-and-go mount to throw the frac or C6 on to look at the moon, etc. It's usable as-is, it tracks nicely with the worm drive, but I'd like to get it back to its "former nights of glory" condition.
      I think it may be as simple as re-greasing the bearings, but I'm not sure what I need to do to take it apart. There is a collar that has two small holes for a tool like a circlip plier, located underneath the RA setting circle ring (at the bottom, where you'd insert a polar scope), looks like that has to come out to break the RA bearings apart.

      I have a Celestron 8" with CG-5 Mount that I purchase about 14 years go. I have not really used it much since due to family and work pressures but as I am close to retirement I am re kindling my interest in Astronomy. Over the years I have lost the polar scope an have been attempting to purchase a new one. My local astronomy shop had what looks to be the correct one in stock bit it would not fit. I Tried both the CG4 and CG5 polar scopes but the tube is too wide. The polar scope for my old mount must be thinner than the later ones. I have contacted Celestron but they can't help. Does anyone know what the problem is or where I might obtain one for the older mount. If not are there any other methods for performing polar alignment without using the polar scope. I have heard of some software that does this but only with GT mounts. I would eventually like to do some astrophotography but it appears that polar alignment is critical for good results.

      Hi all,
      I've previously posted a bicolour version of IC 410 but the other night I managed to captured some SII data so what follows is a Ha / OIII / SII narrowband rendition of the Tadpoles.
      Usual set-up for this kind of thing (CG-5 mount, Atik 460ex, Atik OAG / IMGOH / PHD), but the Ha was captured with both my TS90APO and FSQ-85.
      Ha 25 x 600s
      OIII 23 x 600s
      SII 29 x 600s
      The different fields of view from the twio scopes were reconclied in RegiStar, stacked in DSS and processed in AstroArt 5 and PhotoPlus X4.
      The first of these is what dropped out of the processing, the socond has had the stars tamed by blending in a layer that has had teh AA erosion routine applied. Then followed endless tinkering to try to get the result to look okay on SGL! I've no idea why but images that look fine on my desk top take on a green or magenta hue when posted on here. Maybe part of thr problem is that I don't really like to leave the sky really black as I don't think it looks natural... but on this one I've gone pretty dark!
      Hope you like it! I feel like I've got some good data here; in fact I think that this is the first time I've had decent data for all three channels. It probably has more to give but I am pleased with this .
      Thanks for looking.
