Hello to all!
Posting a photograph of the Summer Milky Way band that I took last week.
However, I do not know how should I feel about this!
This is when the band was right overhead, which is a rare sight for us and happens only when monsoon season is delayed. There was decent glow towards horizon but literally nothing at zenith.
19 degrees north latitude, around Bortle 3 level sky, taken using Nikon 5300, basic lens.
And with this, I prepare to have no view of stars till September ends
Hello to all!
Just posting some of the images I took recently!
(Total first attempt from someone who can't even hold a camera properly)
I was out to conduct a public overnight sky observation event, which was the last event before 6 months of monsoon. For a lot of time, we had cloud cover too!
These images don't include much of editing more than just some basic stuff in cellphone. I forgot to take the photos in RAW so either way I can't do much!
Quite happy with the first attempt. Will improve even more in next season!
Nikon 5300, with the basic 18-55 lens.
Any suggestions appreciated!
Posting in this forum after too long!
One of the first attempts at taking photos of the moon.
All photos taken using skywatcher 90mm refractor with eq2 mount, Nikon DSLR and 2x Barlow here and there.
Basic editing in cellphone.
Thank you! Suggestions highly 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?
The Great Barred Spiral Galaxy ( NGC 1365 ) in the Constellation Fornax

A full size ( 6200 x 4407px ) image can be downloaded from here.
Below the equator, not seen from much of the Northern hemisphere, NGC 1365 passes very nearly directly overhead an observer situated near Cape Town, as Sir John Herschel was in November of 1837 when he discovered this “remarkable nebula” that is numbered 2552 in his book of observations from the Cape.
Not called a “nebula” now, of course, this striking object is one of the nearest and most studied examples of a barred spiral ( SB ) galaxy that also has an active galactic nuclei resulting in its designation as a Seyfert galaxy.
At around 60 M light years from Earth, NGC 1365 is still seen to occupy a relatively large area ( 12 by 6 arc minutes ) due to its great size; at some 200,000 light years or so across, NGC 1365 is nearly twice as wide as the Milky Way and considerably wider than both the Sculptor and Andromeda galaxies.
This High Dynamic Range ( HDR ) image is built up from multiple exposures ranging from 4 to 240 seconds with the aim of capturing the faint detail in the spiral arms of the galaxy whilst also retaining colour in the brightest star ( the orange-red 7th magnitude giant, HD 22425 ). Also, scattered throughout the image, and somewhat more difficult to see, are numerous and far more distant galaxies.
