I'm breaking the cardinal rule here of posting late at night, right after finishing PP, so let's see what sense the dawn brings! 🙃
I shot this in the early hrs of 29th of March. There was no moon present (i think!) and conditions were pretty good, AFAIK.
This is 28 x 360s, so about 2.75 hrs in total. Taken as usual with the D5300, IDAS-D1, and SW 80ED.
APP used for stacking and gradient reduction, everything else done in PS.
Would have liked twice, or 3 times, the data, but it's just not happening, so i've just decided to process what i've got.
Thanks for looking, and all CC welcome as always 😀
I'm totally New to this hobby and i'm having trouble understanding something in stellarium.
I have ordered (not recieved) a Sky-Watcher Explorer 150PDS, which has a 25mm eyepiece 50degrees FOV as a default.
I also have a Nikon D810.
I wanted to get an idea of what my field of view would be with the 25mm eyepiece (30x on 750mm focal length),
and also what it would be With my Nikon D810 mounted shooting prime Focus - no eyepieces.
What surprised me was that it wasnt much difference between the frame and size of the object i get with 30x magnification (25mm eyepiece), and what i get with the Nikon D810 mounted.
I dont get this. What magnification do i get With my DSLR mounted with no eyepiece?
I've been beavering away on a couple of images, one of the Pacman nebula and this, my first Horsehead.
Shot over several nights in my back garden. Terrible weather meant a big gap between imaging nights - it's amazing how you (or is it just me?!) forget the little details in just 8 or 9 days...
Lum data is lacking a bit and I couldn't tame mighty Alnitak. But I like the result.
Anyway, a number of firsts here - first completed image with the Lakeside focuser, first true tests of APT's recently added auto meridian flip (works great!) and first time using Astro Pixel Processor for calibration and stacking. APP is a contender - very easy to use - I threw all my multinight multifilter data at it and it chugged through it all with the minimum of fuss!
4.9 hours of HaLRGB data. L 108x15", R 41x60", G 84x30", B 81x30", Ha 35x250".
Thanks for looking!
Im having issues regarding dew during colder nights while imaging. I’m aware of how to solve the issue of dew forming on front elements of scopes/lenses using dew heaters, however I’m also concerned with the dew that forms on my non-weatherproof DSLR body and imaging laptop. Does anyone have any suggestions on how to combat this?
