Hello, i am having so many difficulties as far as i remember to make some nice flats to match my images.For some reason it it impossible for me to find the secret spot in time and adu for my Flats. This is my equipment : Telescope: Redcat 51 Camera: Atik 383l+ mono (i know the shutter problem that's why i always aim for 3sec and above for taking my flats) Filter Wheel: Atik EFW2 (36mm) Filters: Astrodon Ha & Oiii 36mm 3nm FlatBox: Geoptic flat field generator 164mm (dimmable) Image aquire software: APT Tool v3.71 Software: Astro Pixel Processor This is what i get...i am uploading some images converted in jpeg for the site... Photo A is a MASTER FLAT Ha (Bin 1x1) created with 30 Darks, 50 FLats (3.7sec adu 22000), 50 Dark Flats, 100 Bias Photo B is a MASTER FLAT Oiii (Bin 2x2) created with 30 Darks, 50 FLats (5sec adu 46000), 50 Dark FLats, 100 Bias Photo C is an example result of stacking my fits of Helix Nebula at Bin 2x2 , with the above calibration master frames (this is the Oiii in this case) Are my calibration frames Over correcting ? if yes what can i do ? Is the Optical path problematic ? as i can see at photo A ? what can i do , what to check ? I have checked also the filter wheel position related to filter change , but it comes centered...i couldn't see a fault on it. i Believe i have a problem also finding the correct ADU value....i made any experiments by changing the adu value and i have tried at 22000, 32000, 47000 by using the CCD Flats Aid.......but nothing all come out the same. I hope someone can help cause i am loosing my mind and my fits
I shot this over 6 nights. We had an amazing go of clear nights in a row. Now it's all rain until next week. But while it was clear, I managed two nights per filter on my newest scope. A total of ~ 760 3 min images. I think the total imaging time was 37.8 hours. Shot it through my newest scope the RedCat 51mm. It did well, but could have used a belt focuser. I managed to get one together from Moonlite, but only just after imaging this. The scope was able to hold focus a good bit of the night, but the quality curve looked like a swan dive towards the end as the scope lost focus at the end of the night each night. I got out my old trusty AVX to manage the aiming parts of the setup. Guided by an old Orion SSAG I had lying around and a recently acquired ZWO Mini guide scope since it matches the RedCat so well. But I think I'm going to need to swap out the guide cam for something with smaller pixels. Overall though, it worked. Main camera was ZWO ASI 1600 MMC. I used 5nm Astrodon filters.
