What phone do you use

Just a cheap 2nd hand iphone SE (iphone 5.5).  Does the job. Only use it for calls, txts photos and internet hot spot sometimes.

Yes, corrector. Celestron ones are cheaper but don't fit the skywatcher ones, they are unfortunately a few 100 more in price. Could be anything, cosmic rays, natural radioactive isotopes in the air or the materials in the camera itself or the nearby parts of the telescope. I tried this once with an ...

I don't have any hot pixels though, barely have any in the raw files as it's a cooled camera.  I need more data to fill in the missing pixels, hence why it's still grainy.  10 lights is not enough, need about 30-40 I reckon, or more would be even better.  The darks and bias help improve the SNR. But...

I reprocessed the same lot of images again in Pixinsight but a completely different way based on another tutorial I found and it got rid of the fogginess in the middle from the vignetting effect. Much better but it's more apparent it needs much more light and dark frames as the fog was sort of cover...

A very PC discussion

The availability of GPUs makes it impossible to get the models you want. I want to get a 6800XT with water block or comparable with one I can buy.  I can get the Red Devil standard and limited edition at somewhat inflated price on ebay (relative to the Aussie MSRP anyway) but blocks are currently on...

The 3090 is the only card somewhat available here in Aus, but at an absurd price of $3500, considering the 1080Ti was only about $1100 when they first came out here.

Just did a crash course on Pixinsight and managed to finally get an image. Much better SNR using that compared to DSS. I did a little editing to boost the colours and contrast but tried to keep it more natural compared to the above pic which was done in DSS. Neb1.PNG Vlad, there are a couple of oth...

Figured there is no limit to the sensor temp, it's 30 below ambient.   I got it to -19.8ºC last night but that was maxed out and it was low teens ambient.   On the colder nights it gets down to 5-8 even in summer, winter is about 0 - neg 3.

So on a clear winter night should be able to get -30

Nice!  How do you get the sensor temp so low?  Also what scope do you use?

The sensor can go 30 below ambient.  Not sure what the limits are.

The scope is a sky watcher 200mm F4 pretty sure.

Finally worked out how to get Nina to work with the auto focuser, plate solving and the imaging itself with the sequencer. It was very windy out so not the best but fist light with the ZWO colour camera.  Spent so long with learning how to get things to work the night was long before we ever got som...

It sounds intriguing!  where did you purchase it from?

My friend got it from Bintel, one of the biggest optical retailers in Australia. It was the only one available in the country of that model since covid has made everyone buy everything up.

Yeah you attached it to one of the knobs and configure it in the software, in this case Nina which will take care of everything pretty much, from imaging, focus to plate solving.   The issue now is learning how to configure and use the software.  The idea is the focuser talks to the camera and vise ...

My friend just bought a ZWO ASI2600 colour camera and a ZWO advanced auto focuser. 

Should arrive next week.  We are going to have a bit of a learning curve to work out how to use it with Nina.
