Tonight's budget test, using ZWO T2 to 1.25" adapter as DSLR clip in filter.

I'm going to try this tonight with my Canon 600d:

Thats the ZWO T2 to 1.25" adapter with a baader 1.25" moon and sky glow filter. It fits very snugly into the circular clip in area with no movement in any direction and you have to give it a good pull to remove it. The blue tack is just there as a precaution. The baader filters have a wider useable area than some other filter manufacturers so I'm hoping they'll be little to no vignetting. I'll let you know how it goes. 😬

Great idea. I saw this done before online so I 3D printed my own holder. Because it is so close to the sensor it calibrates ok with flats, but there will be vignetting

Thats the professional way of doing it, nice one. I'm not sure what the clear aperture is on a clip in filter, but the Baader has 27mm.

I’ve done this too, the other way round 😂

Beats spending a couple of hundred quid on a new filter.

Yes and I use blutak too.

Managed to get some good data for the Heart and Soul Nebula and the filter is definitely helping with this, so I'm pretty happy with the outcome. There's definitely vignetting but nothing flats can't handle. Here's a heavily stretched flat:

Looks pretty good indeed. My flats are a lot worse with my scope and 2” filters.
