    Compact and stable tripod for Opticron MM4 Price up to 400 Euro

    Hi, the price might work out for a used wooden tripod... but <45 cm packed length and sufficient height will not work for wood as far as I know. Joachim, who did a quick scan though the Berlebach site and didn't find anything...

    Hiking tripod for Kowa TSN-663M

    Hi, I agree that a tripod with 1,50m height will be fine. I just checked my setup and the upper edge of my fluid head is at 1,51m. I am 1,88m and when I use my angled scope alone, I just look down into the EP no need to bend my back. So with a 1,50m tripod, 10cm head and 15cm scope an observer...

    Celestron Spotting Scope advice please?

    Hi, first of all, welcome to BF! The F-ED and M2 ED models are optically identical afaik - the former are quite a bit heavier though... but does that really matter with a 100mm scope? 400 quid sounds good for the old one if the objective is good... make an artificial star, learn how to do a...

    Compact and stable tripod for Opticron MM4 Price up to 400 Euro

    Hi, my 128RC is 10.5cm w/o QR plate, so probably no dice leaving it on and fit into you backpack. The usual K-20X ball head sold as a set with the T2204X is 9,8 cm with plate but it can be tilted 90 deg which will probably trade 3 or 4 cm in height for some extra width... and you can also try...

    Compact and stable tripod for Opticron MM4 Price up to 400 Euro

    Hi, the 40cm limit makes things kinda tricky if you still want a reasonable height around 130cm - plus 12-15cm for a video head plus 10cm for the angled scope & EP plus 10cm distance from your eye level to the top of your head... a little bending down is kinda necessary and even 10cm are no big...

    Compact and stable tripod for Opticron MM4 Price up to 400 Euro

    Hi, first of all, welcome to BF! Some more info is needed. What model of the MM4 did you buy, there are 3 apertures of 50, 60 and 77mm (each having different dimensions, weights and magnification rages), each in straight or angled (this makes a difference when determining the needed height)...

    8x32 advice?

    Hi, first of all, welcome to birdforum! If you can get a used SF 8x32 for what a used UVHD or FL would be, I would strongly recommend to try it and decide for yourself. Joachim, who likes his FL... a pair of SF was not to be found in budget...

    New but probably wrong insight about lowlight

    Hi, @Binastro I agree, but I did not mean astro use. @Swetpat I think that this discussion has taken place before, not sure if with you or how it went. My argument was and is that the objective lens is illuminated with a certain number of photons per area unit. Thus a larger objective lens...

    New but probably wrong insight about lowlight

    Hi, actually both. Same exit pupil but larger objective aperture means more photons per area unit. But the increases magnification helps too. Joachim

    New but probably wrong insight about lowlight

    Hi, for astronomy aperture is king for many reasons, but the main one is that it limits resolution so you can see smaller objects. Provided that your eye's pupils still can widen enough and your skies are dark enough, you also want a wider exit pupil (and thus less magnification) with that...

    Looking for long eye relief binoculars

    Hi, not sure if it is in budget, but all Conquest HD models are infamous for providing more ER than some folks w/o glasses can use, especially the 42mm models... Zeiss sends out longer eyecups to those poor souls on request. Joachim

    Nikon Monarch Fieldscope vs Celestron Regal M2 80ED vs Vortex Diamondback - tough choice

    Hi, great to hear that. Please take some time to test its optical quality inside the return period if you bought online. Either by doing a star test (real or artificial star) or at least try it in good seeing (early morning or on a cool overcast day) and see if you can get a crisp view at 60x...
