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 😀
This is the first lights of my ASA 12"N f/3.62 (purchased in 2007) with my Moravian G4-16000 CCD camera using one KAF-16803 chip of 36mm x 36mm (4K x 4K).
The adjustments, collimation, ASA OK3-Z pression screws, asked a lot of attention.
For a precise collimation, i use the CATSEYE XL & XLKP kit.
This is the first 3hrs of exposures taken the last weekend in one night. The second night was too windy unfortunately.

I just picked up a Skywatcher Evostar 80mm Doublett and LX70 (EQ5) mount. This is my first refractor and EQ mount so it took me a while to put it together (if you all notice anything out of place please tell me!). I still enjoy my 8” dob but wanted to learn. This type of scope. It had good reviews for general viewing, but I'm not sure what to expect.
The EQ mount took quite some time to figure out and one of my questions is do I operate the scope with the counterweight horizontal to the ground? I noticed that in that position I can use the control cables to move up and down and left and right. Any advice is appreciated!
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?
