which webcam is best for planetary imaging under 25 USD . If you have experience of any webcam for planetary work please help me out
Does Focal Ratio affect brightness or is it all about field of view. Will an f/5 scope show the Andromeda galaxy more brightly in the eyepiece than an f/12 scope, or is it just about fitting Andromeda in there and seeing more of the sky? Also does the Focal Ratio of a scope have any effect on the amount or length of exposures taken in astrophotography? Thanks.
Hi, my current telescope is Celestron ExploraScope 70AZ, thinking upgrade to skywatcher heritage 130P(came with 25mm ajd 10mm EP) , if i do, can i use the eyepiece (4mm) and x3 barlow from my old celestron on the 130P?
One more question, i ordered a eyepiece camera Svbony SV105, i wonder what is magnification of this camera and how it work to change magnification.
Just thought i'll bring this up as a point of discussion. Today, cooled CMOS Astro Cameras are available in plenty. QHY, ZWO and other variants of the same camera are selling for very reasonable prices. However, there was a point of time when astrophotographers used to cool down their DSLR's as a cheap OSC alternative to CCD cameras. Give a choice, I would've purchased a dedicated CMOS OSC which can cool to 40 C below ambient, but since I had a Canon 500D which I had self modded, I requested a friend Kaustav Chatterjee (an avid model railroader) to cold mod my 500D (he had cold modded his 1000D long back). This newly modded camera has a TEC12703 single peltier and cools to approximately 20 below ambient.What do you guys think?
Recently i bought this brand new camera from David Hardie when he was doing a big sell out of some really nice items in excellent offers !!!
Unfortunately the camera although brand new doesn't serve my purposes so I decided to sell it at exactly the same price which I bought it from David , it was a really special offer 🤪
The camera new costs £1685 and I will sell it for £750 to be fair....🤪🤪🤪🤪
Camera comes with all its extras and case in absolutely brand new condition....!!!!
