How do you have your scopes rotated so the camera sits on top ,hangs on the side,or hangs underneath?
Thanks

Hi so the 12v as working but I dont think the sink and fan can get rid of heat quick enough it is blowing heat but camera temp not cooling , so new bigger sink and combined fan turning up tomorrow .

So you are trying to cool it just enough to regulate the temperature to make calibration easier?
I was re-packaging a Meade DSI-pro II to provide regulated set point cooling. The finished camera cooled to 35°C below ambient air temp. I usually ran the camera at -15°C
Sealing the camera to prevent condensation on the sensor was a bit difficult but I did get it to work.John Love

WD5IKXM27 Single 600 second sub at -15°C
Yeah I dont want to have worry about condensation , I have rewired to take my 12v plug so will see how it handles it without sensor atm although i do have one if required . With my eq5 pro mount anything over 120 sec subs produces egg shaped stars and with the small pixel 178mm its prob never going to get any better .

Haven't considered running a Peltier TEC off a battery (other than something like a car/caravan battery). I have cooled the astro camera in my ASC - an ASI178MC, using a good quality Peltier TEC - Peltier Module, 54.6W, 4.4A, 20V, 40 x 40mm. Running this off my 13.8v main observatory supply and using water cooling of the hot side, I can get the camera temperature down to -12°C with an ambient temperature of 15°C. The TEC draws around 2.5A.
Yeah looks like I'm resorting to a 12v 3 amp plug ,using a small fan trying to keep the weight down as dont want to start tilting ,haven't connected controler yet not sure where to put sensor probe .

The 7.4v battery couldn’t cool below 17 degrees (Ambient) so I will have to wait until I get the 12v power supply sorted And a bracket and larger sink fitted .😩 this Astrophotography def test your patience.

Hi all
My normal image train
Camera,1.25 efw, coma c,scope
So I purchased 2" optolong moon,skyglow to LP all filters (lrgb) but I could not get focus with B mask and wouldn't plate solve even with close focus the display on tablet for asiair was very grainy .have taken filter out now and plate solved and B mask no probs any idea why I wouldn't work?
Thanks oh I screwed filter into cc .

Bad news battery just died at 2 hrs 😔 went out to start setting up a noticed it has died on me so now recharge battery and as there is a haze in the sky atm not to bothered .

I'm having a few issues with this target myself data ql not being that good, apparently it's not a easy target.

I'd be interested to know which fan, heatsink and peltier unit you used. And where you got it from?? If you don't mind sharing.
U want me to see if it works first lol

Low voltage battery only 7.4v so not running at max .I do have a control unit but will prob only use if needed (12v) i tried it last night and it only took camera temp down to 11.6 degrees that was 5 below ambient. But going to image tonight and just see how it goes .🤞🏻 If it goes well then a good tidy up and lagging will be next.

I would use 2" LPS filter and I would put it in front of CC, so it would be:
camera, FW, CC, LPS filter, scope
Hi I've just ordered the optolong 2" moon and skyglow as it's the only one I've found with ar coating (fairly cheap) what do u think any good.

I am going to guess that heat sink will be too small but it really depends on how many watts that peltier is. A water block is a better bet, unless your going to enginear it like tomato above. Too heavy is a problem too as it will cause tilt...its a small sensor mind you.
Have a larger heat sink now.

Hi all
If using lrgb filters in a filter wheel 1.25 would it be advisable to use a LP filter in the image train and where would I put it ? I presume it would need to be a 2"
Camera,filter wheel,coma c,scope where would it sit?
Many thanks

Hi all if u have a great night shooting with total error @0.8 how can the next night same target nothing changed can I be getting 1.8 total error ?
-
Hi has anyone had any experience with this filter?, having one in filter wheel would be a lot easier .
Thanks

Hi all
the 178mm has pretty small pixels and when my subs are 100 secs the stars round but when I go to +120 sec subs the stars elongate a little. so if I binned 2x2 that would make the cam a little less sensitive therefore I could increase expo time and keep rounds stars . Is that right ?
Thanks

I have a ankle weight wrapped around the back so that it isn't so front heavy ,but I like the idea of counter weighting the camera, filter wheel will try that.
