Millions of Suns, M52 & Bubble - QHY8 OSC


Recommended Posts

Last night was one of those rare evenings, it wasn't even suppose to be clear but it was!

Only managed 1 hour of integration..

20 x 180second subs

50 flats

50 bias

Quattro 8s

Will definitely have another go at processing this, only wish I had gone for 5 minute subs :(

Thanks for clicking..

That's a really good first process Guy - and with a quatro 8 as well - I don't see many of those around but they seem like they should be a good fast scope - certainly works for you :-)

Nice one Guy, is this uncropped? If so, I think youre pretty close to 100% round stars - the only hint of dodginess is a couple of stars in the far top right corner.... I'd be pretty happy with that!

Thanks Rob

The autocollator works a treat, nothing but a tiny left hand crop due to stacking..

Looks nearly perfect :)

Ahh, I was going to ask whether this was pre or post autocollimator.

Was this using the MPCC MkIII too?

Yes Rob, Baader MPCC MKIII , 34.47mm  spacing assuming that the QHY8 being as per drawing at 20mm  (total 54.37mm)  :)

When I rotate the CCD in the focuser there is some slight coma, I'm going to try getting that .63mm back from somewhere   :D

little rubber bands help. That'show I did wit my DSLR's, the MPCC MKIII and the Orion Optics CT8 900mm/f4.5. it's almost perfect...:-)

      Hello everybody!
      I measured my setup times when i did my last imaging run. Absolutely shocking 🤔 
      Step 1: unmount 8" quattro, disassemble EQ6 into 3 parts, move parts to terrace and reassemble EQ6, remount 8", without counterweights: 6 minutes 50 seconds (correct position marked on terrace, with right arm hurt, good time ) 
      Step 2: Mount counterweights and set scope to park position: 1 minute 55 secs
      Step 3: Connect power sources and connect all cabling: 20 minutes
      Step 4: get the computer and software running (on a very good night): 10 minutes
      Step 5: Let my old QHY8 cam and the scope cool down: 1 hour - otherwise i get strong gradients!
      Total prep time: 1 hour 39 minutes. Obviously, the cable time could be improved massively by training. But even if we could get the cabling time to zero, i'd get only down to 1h24', with the total time being dominated by the cooling of my rig.
      Open question: As i would not leave my cam outside, there seems no real possibly to cut down significantly on my prep time, even with a small obsy? Or am i doing something wrong?
      Best, U.
      P.S.: Getting an expensive cam is right now no good option

      I recently upgraded to a purpose made astro-camera (Atik Horizon Color). The learning curve has definitely been noticeable, but I cant figure a couple things out.  For some reason the pictures are grey scale when using N.I.N.A. I have tried different binning and formats, but the image is always black and white. 
      If I use the ATIK software (Infinity,Dusk) there is an option for 'Color Binning', and that seems to have fixed it for those programs, but N.I.N.A doesn't seem to have that option (you can not select anything for binning, or select 1x1, 2x2 ect.). But what makes it weirder is that the preview is always color using N.I.N.A. I used a pinhole lens cover to take pictures of my computer screen and it always shows up as color images. However, if I take that exact image file that previews in color and move it to pixinsight, it is grey-scale. 
      Is this a binning thing, file format problem? At this point I am just confused, if the preview of the image is color shouldn't the image data be color as well?
      So far all the problems I have had with this camera have just been simple things that were new to me, but this one is really throwing me for a loop. Thanks for any help. 
      I've attached a couple images. The first you can see the NINA preview is color, as well with the couple other I took in the bottom right. And the other in a photo of trying to color saturate the stretched image in Pixinsight, and it says that it cannot saturate a grey-scale image.  I have tried this with Tif, Fits, and various binning types.

      Hi, this question has probably been done to death here, but can I ask the community to help me decide on a new camera?
      After struggling with my very glitchy QHY5LIIc camera for a while, as well as having a forced break from astronomy, I have decided to get a new camera. After all the problems I've been having with the QHY, I really don't want to use this manufacturer again. I know lots of people use them quite happily, but once bitten ...
      I have been looking at the ZWO cameras - OSC, as I haven't the time, clear skies, or patients to do LRGB imaging!
      I have about £250 to spend, which I may be able to push to £300 if I wait a bit. ? So I've been looking at the ASI224MC, ASI290MC and the ASI178MC cameras.
      I mainly do planetary/Luna imaging, but I have also dabbled in a bit of DSO and would like to continue with both. I have a C9.25 and a ST80 guide scope. I know these aren't ideal for DSOs but please humour me!
      I think from the specs/information that the 224 is probably the best option. Although the resolution and QE are the worst of the three, the well depth and read noise are the best and the fps is pretty good too.
      I don't know if there are better/cheaper cameras using the same chips, such as Altair's range. I just don't want to make the same mistake that I did with the QHY!n
      Any help/advice you can give will be much appreciated.?

      Hi everyone,
      A bit of an odd one aspect ratio wise, but fun to put together - first light for my new ASI294MC OSC and technically my first experimental attempt at a mosaic!
      My first stab at using the camera meant I went for 30 second subs, I need to experiment more to settle on my ideal sub length...still, the results are decent for a low integration time of 1.7 hours.
      I love the Orion constellation and if I had the skies and time, I would mosaic the whole thing, but failing that, I can do bits and pieces! Orion's Belt is amazing to me, the three stars, Alnitak, Alnilam and Mintaka, very distinctive in the night sky.
      Full details on Astrobin.
      Thanks for looking!
