Venus imaged during the afternoon of 20.04.2018. Although imaged in broad daylight, the very short exposures required, just a couple of miliseconds, means the sky looks black. Such short exposures are required to prevent the image over exposing as Venus is so bright. Celestron 8SE and QHY5L-II monochrome camera with Celestron LX 2 x barlow. AVI stacked in Registax with minor adjustments in wavelets. No post-processing other than a slight crop.
I know the topic of DIY autofocusers has probably been done to death, but just thought I would share my experiences of making one this evening. I got most of the technical / clever bits from Motionco, and two metal brackets (for attaching the motor to the scope) from B&Q. I have got to say that this was quite a bit easier that I was expecting it to be. Making the bracket and attaching it to the scope took ~3 hours, but this was me taking my time and following my old dad's motto of measure twice, cut once . As a result, I did not [removed word]-up at any stages, a very rare occurrence for me . I wanted the motor to be very easy to attach / remove in the dark, and I think the bracket I have ended up with does a pretty good job, it is just a pity it looks a bit ugly . Got to say that it works brilliantly, and the main reason I built this was because I was finding it really difficult to get my arms in to position to focus the scope, while trying to look at the laptop screen during imaging, with the image was jumping about all over the place every time I touched the focuser knob . Now I can just do this really easily, straight in front of the screen and the focusing control is really fine, much better than I can do with my hand and virtually no image wobble. Here are a couple of pictures, and if any one is remotely interested in how I did it / exactly what bits you need to buy, please post in this thread and I will add step by step instructions with pictures, but not tonight, I need some sleep . A few quick pictures:-
Hey StarGazersLounge Forums, I am an amateur in astrophotography and have so far taken photos of the Moon and some planets with my camera. However, I am looking for a major upgrade in order to take astrophotography to a professional level as I have long been passionate about astronomy. My overarching aim with astrophotography is to take high quality photos of many planets and continue my interest with the universe. I would be very grateful if anyone could recommend the best set up regardless of the price at the moment as I will work from there. This includes a camera, mount and eyepiece for the Celestron 8se etc so I can get a good idea of what I need to get some amazing planetary shots. By the way, for the camera, I am considering the Sony a7r iii (good choice?) for astrophotography and nature photography as well. Any form of advice would be much appreciated. George
