    Hello!
    We are going to buy the ASI1600 but need a bit more space for filters and our interface. The 21 mm adapter looks good but I am a bit confused where the inner/outer threads are for this 21 mm M42-M42 mm adapter. The different images are a bit misleading. Do you have and can you please send me a drawing or step file of this and maybe also other available adapter? Thank you!
    Best regards,
    Michael
