Thanks for sharing your design @ollypenrice 👍🏻 “often copied, never equalled” 😝

@paul mc c when you click save it should bring up a box and you choose how to save it

Yes, one to push and one to pull. It just looks like the screws are missing on the QHY one. I'll see if I can find small enough grub screws at home, or more likely have to order some.

I dont think what I'm suggesting is any different to the equivalent ZWO camera?

The little empty holes (x2) either side of the starhead screw are threaded. I could buy some grub screws and use that to adjust the tilt?

This is the message on cloudy nights from the QHY vendor, after seeing the above photo: I cant make head nor tail of that. I want to test the camera on the bench to rule out sensor tilt before starting to look at the scope.

I'm struggling to see how to adjust this so-called tilt adapter plate. Could anyone please help me !!

Yes I've checked it, and rechecked it

It does look green and the Ha and Sii are red. Any suggestions on a test target, looking clear later?

Anyone have any ideas what is wrong here? I imaged the Squid over several nights, and spent three of those on Oiii. I stacked the data but there is very little sign of the Squid. The fits header says I used Oiii. I just pulled the camera and filter wheel off the scope, and checked that Oiii is correctly placed in position 6 of the wheel. I did several tests earlier on the EFW and the wheel always went to Oiii when chosen in SGP. To me this looks more like Sii, so I was wondering if the EFW went to position 7 instead of 6? But I am finding it hard to believe that the software/filter wheel found the wrong position 3 separate nights in a row. I'm assuming this is user error on my part, just not sure where I went wrong? Any suggestions welcome! I also did image the squid at the same time with an NBX filter on another scope, and I can see the squid, using same gain and exposure settings (and a slower scope F4.8 versus F2.8). Fits attached of Oiii 300s sub, QHY268M, 4nm Baader Ultra Narrow High Speed 2" filter. Also attached 1) jpeg of stacked Oiii data with stretch in APP - QHY268M 2) jpeg of stacked Oiii data (from NBZ filter) with stretch in APP - ZWO2600MC Any input welcome. Adam.

Maybe remove one filter to do the test?

@ollypenrice did you adjust the face of the camera each time, and set it back on again? Do you mind briefly explaining how you adjusted it if this was the case

I really hope this works! I've a sensor I need to check and I'm itching to knock up something like this.

Mind blowing Tristan. What an image.

Recently I’d spend more than one night on a single target. Definitely spend the whole night at least on NGC6888

Cheers Dave. I didnt try a different light source but I did rotate the light 90 degrees on the OTA and the pattern didnt change, so I wonder is it a mark on the sensor glass, maybe a water/condensation mark? I'll pull the camera off the scope tomorrow and take a look at it.

That looks brilliant -both the image and the rig. Nice to see you sharing the STLs etc for the wider astro community too.

Any ideas what could be the issue here? Cant see any frosting on the sensor, and it's in at least two filters I've tried Ha Sii. The bottom left corner it is most obvious.

I’m imaging at F2.8 Tak Epsilon 180

@Andrew_B thanks Andrew. Looks like a good choice 👍🏻 @vlaiv cheers! The TS is on his options but worried about importing costs.

I think it must have been cropped. He has a 600d and is saving for a bigger mount. I’ve asked him to sign up here and learn from the best 🤪

It’s not for me, for my nephew he wants a better scope than the ST80 he’s currently using. He’s not off to a bad start mind you, I’ve attached his M31 below:

A very non technical answer Vlad 😂☺️

Wants longer FL 👍🏻

What would be the general consensus for a small scope for the SA, to be used with a crop sensor DSLR?
