----------------------------------- dragos.n 20 Oct 2024 04:32 SkyWatcher HAC 125 ----------------------------------- Am descoperit acest telescop, sau mai degraba obiectiv-astrofoto pe Aliexpress. Apertura 125mm, focala 250mm, reglaj de focus in fata. https://www.aliexpress.com/item/1005007635178810.html?spm=a2g0o.detail.pcDetailBottomMoreThisSeller.4.5567Kt67Kt67d9&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.291025.0&scm_id=1007.13339.291025.0&scm-url=1007.13339.291025.0&pvid=006f348f-e8cb-4c77-bb38-9816f17466d8&_t=gps-id:pcDetailBottomMoreThisSeller,scm-url:1007.13339.291025.0,pvid:006f348f-e8cb-4c77-bb38-9816f17466d8,tpp_buckets:668%232846%238114%231999&pdp_npi=4%40dis%21RON%213663.70%213627.05%21%21%21780.64%21772.83%21%40211b813f17293871123852817e8149%2112000041587825595%21rec%21RO%21738892859%21X&utparam-url=scene%3ApcDetailBottomMoreThisSeller%7Cquery_from%3A ----------------------------------- zoth 20 Oct 2024 07:38 ----------------------------------- I tested the HAC125 three years ago. We’ve were asked numerous times at NEAF about this scope due to the video. We have no intention of bringing the HAC125 to the North American market. There are actually a few reasons as well: 1) You can only use 1.25” guide cameras with it. You are not able to use popular cooled cameras such as the 533 or 2600. 2) Focus is done via a helical in the middle of the corrector. There is no way to automate it and your hand blocks light when focusing. 3) You’re very limited on filters as they can only be 1.25” as they have to thread onto the front of the guide camera. The telescope uses a very interesting optical design. I do hope the technology used in this telescope will be applied to others in the future. I would consider this a proof of concept for our ability to produce interesting reflecting type optical designs. So while the HAC125 is very interesting it is quite limited in the modern era of imaging. I would see people getting this and being done with it a week later. But I do hope we see some of the tech used on future telescopes. Extras de pe CN, post din 23 aprilie 2024 ----------------------------------- dragos.n 20 Oct 2024 16:32 ----------------------------------- E buna de obiectiv pentru o camera de ghidaj. Sau sa faci selfi :D Ma mira faptul ca totusi, dupa 3 ani, SW au pus-o pe piata. Totusi, cred ca s-ar putea motoriza focalizarea, folosind o curea si in motor pus la exterior. Dar chiar si asa, nu vad rostul ei, mai ales avand acest pret. ----------------------------------- zoth 20 Oct 2024 18:04 ----------------------------------- Mie imi suna mai degraba a experiment ratat. Prost gandit sau mai bine zis gandit cu picioarele. Si ca intotdeauna experimentele fie ele reusite sau ratate sunt platite din banii astronomilor amatori. Ca asa-i la vie! :) ----------------------------------- dragos.n 20 Oct 2024 21:19 ----------------------------------- Poate SW vor lansa vreo camera cu senzor APS-C, sau macar MFT, care sa poata folosi tot campul vizual de 3,7 grade al ciudateniei, montata intr-un corp cu diametru de 4cm, hai 5cm. Asa s-ar justifica. PS. Stiu eu niste indivizi cu un ego infinit. Cred ca le-ar place sa puna un ocular in acest telescop, si sa se vada foarte mari :D :D ----------------------------------- dragos.n 02 Noi 2024 04:07 ----------------------------------- Un astronom a gasit modul de utilizare a acestui telescop. https://youtu.be/n_khfPbxbI4
