  1. Hi all! It's been a while since I wrote here, also because this year I've been less active in the field, unfortunately... Anyway, I've now started to do autoguiding, with mixed results. I bought myself a laptop and guidescope, with CCD. I'm able to do 10 minute exposures that come out fairly well most of the time. Guiding is mostly good. I tried PHD as well as Maxim, but lately Maxim seems to be doing better, or I just found the sweet spot for my setup. The last 2 or 3 times however, I'm having difficulty in obtaining decent images. Even with no moon, the images I get are q
  2. excellent tutorial!!! thanks a lot!!! looking forward to putting it in practice!! :-)
  3. I also don't really like the stacking and calibrating Maxim does. I always return to DSS. but maybe that's my inexperience... in all Maxim seems a bit too complex for me... I will definitely give PHD a try... Is it easy to get up and running? is it intuitive, or will I have to look up some stuff here on the forum, and elsewhere? for that matter, is there a PHD tutorial? a quick google resulted in the manual from PHD. I'm guessing there's the world to be found! but any suggestions as to good points where to start learning PHD would be appreciated, if available :-)
  4. hmmm. food for thought. in fact in my astro club there is a dichotomy between who uses maxim and who PHD... But the astrophoto course they organise focuses on Maxim, so I started with that...
  5. Hi all! Yesterday evening I finally was able to have a success with my new setup. Since february / march I have been struggling with getting autoguide up and running, but due to various mishaps and lots of bad weather, I haven't been able to produce a single image, up until now. This is what came out: M13. As you can see the stars are not very clean... So guiding apparently wasn't as good as hoped for... I also used flats, but there still is a bit of a gradient, but a lot less than previous. These are 180 sec exposures at 800 ISO, so I guess I have to be at
  6. Had some help of a friend this evening. Turns out it was the usb cable in the end.... ? He also helped me with some of the guide settings in maxim, so that is a good thing coming out of this! ?
  7. That was actually what I was hoping to find out today: if the combination of QHY5 and finder scope would be able to reach focus. I actually almost had it fixed, when using EZPlanetary, lowering the gain and exposure almost to zero: I finally saw some shapes and shadows moving when I had the scope, by chance, in my hand instead of on the mount. So I used those settings, put the scope on the mount again, adjusted focus so some far away trees were in focus and was moving the mount a little to center on an even further away object, when my laptop stopped recognising the QHY5! I
  8. some additional info: Maxim does not balk when I disconnect the USB cable from the QHY5 when it is still connected in Maxim, as it does when I disconnect my DSLR... so it seems it's not communicating perfectly... I must have installed the drivers 5 times by now...... moreover, in EZPlanetary, the image I see (see before: from totally black to totally white, depending on the gain and exposure time I set) changes when I pass my hand in front of the finder scope (with the QHY5 attached. so the camera DOES send a signal to the pc... only not the real image, apparently.....
  9. Hi all! I'm embarking on the autoguiding path... Obviously not everything is going smoothly... So, I have the new QHY5LII Mono for guiding on a Celestron 8x50 finder scope. I had already tried capturing images with maxim, from my main scope with the reflex on it. That seemed to work alright. I installed the ASCOM platform, the drivers from the qhyccd.com site (system & ASCOM), and also EZPlanetary. Maxim connects to the cam alright, but all I can get from the camera is noise, black images, or white overexposed images. I tried all USB gates, reinstalled a
  10. I was (as usual) in an open field, away from buildings, and other normal sources of warmth. totally exposed, and no wind. I will definitely try the box.
  11. hmmm, I always have to go out, so this would not work for me. I'll be trying the cardboard box :-)
  12. doesn't this compromise battery duration? I have my laptop and HEQ5 mount on an 18Ah battery, so must be frugal... :-)
  13. Hi all! I just recently bought a laptop for using Maxim with my imaging (for now just shooting the pics, not guiding yet), and I immediately was confronted with the problem of humidity. On the first night out the pc was covered in moisture after an hour or two. I had to wipe the screen to be able to make out the Maxim windows... Does anybody have any tips on how to minimalise this, and avoid problems of shorting the motherboard, etc? Apart from keeping my fingers crossed, the only thing that comes to mind is a lapdome... Any thoughts appreciated!! Gerhard.
  14. Hi all! I am kind of frustrated that I cannot find any source of DSO info that specifies if an object is visible in visible light, or only when putting on certain filters (like H alpha). The other night I took some subs of IC410, but nothing showed up on the stack... Wiki also does not specify in what bands it emits... Is there a site, or other source that specifies this info? For now I only have an un-modded DSLR to shoot subs with, so I need to know if something will show up or not... help!! :-) Gerhard.
