The more I think about it, the more it seems the likely source of the problem. Looking at mine, it's like yours - it has a M42 male t-thread. Unscrewing it there is just an M55 male thread. The kit above is designed for a canon dslr and includes an M48 canon t-ring. So it's different and spacing must be different. Without the included M48 t-ring it will work fine with an astro camera with appropriate t-thread spacer. But for a dslr, you need the kit to get the right spacing. I don't think the above kit is specific for the Starwave. Rather, I think it's the kit you need to connect a canon dslr. The obvious, and quickest, way to resolve this is to contact your supplier and ask them Louise Link to comment Share on other sites More sharing options...

Is that why all the blue dots are in the top left quadrant of the target? Link to comment Share on other sites More sharing options...
Thalestris24 Posted March 26, 2019 Share Posted March 26, 2019 Hopefully, aa will clarify. There is obviously a problem but the problem isn't obvious! I didn't think aa sold direct anymore as they have all their retailers - but I could be wrong! Link to comment Share on other sites More sharing options...

Anthonyexmouth Posted March 26, 2019 Author Share Posted March 26, 2019 I see from your sig you use a filter drawer, any reason over a filter wheel? Link to comment Share on other sites More sharing options...

Only about 15mm in optical length though the threads are a bit iffy - https://www.teleskop-express.de/shop/product_info.php/language/en/info/p3979_TS-Optics-Filterschublade-fuer-2--Filter---M48-Anschluss---Laenge-15-mm.html I only really use them for H-alpha. I have a fw on the 115mm Apo. I don't think I've used the setup since last summer. It's hopeless here I've been doing short exposure / live stacking instead, when I can and mostly just with a 200mm lens. Louise Link to comment Share on other sites More sharing options...

Well I emailed them that night, got a reply about 30 mins later at 10pm which I thought was amazing, said he'd look at it in the morning and let me know. Heard nothing so emailed this afternoon and as a side note asked about the sensor distance on the 1600. Half hour later got a single line reply stating the sensor distance is 17.5mm. I'd already said that in the email. Disappointing reply considering I'm asking a question on a new product and maybe wanted to buy one. Link to comment Share on other sites More sharing options...
