Hi everyone.

Looks like I will get some favourable weather in the coming days, but the moon is out and full. I finally have a car so I can get away from light polluted Weymouth, and tonight I took a drive and found a great spot to shoot (see image).
So to the point, I want to shoot Andromeda during these moonlit nights since the moon will be directly behind me. How much will it still affect my images?
I'm still a beginner, using a Nikon Z50 and the 50-250mm kit lens @250 (F6.3), but I do have a Star Adventurer now, so I'll go out and shoot if nothing for the practice (my polar alignments have been pretty good).

Didn't end up with as many subs as I would have liked due to my inexperience, but it turned out okay. Just goes to show, I doesn't matter how many YouTube videos you watch, actually going out there is much more valuable.

No moon Friday, but not as many subs as I would have liked due to clouds rolling in. But I'm happy with this M31. This little Nikon Z50 and kit lens really is good. Last night was completely clear, so I thought I'd see what this un-modded camera could do with the Rosette, wow, not a bad 1st attempt.

They are fantastic images, how many subs and settings on both images did you have. The rosette nebula with your unmoded dslr is fantastic 👌

I didn't use any darks, just flats, as the lens produces a heavy vignette. For M31 I only had 36 useable (as I said the clouds rolled in) 90secs @ ISO1600, and I had 70-80 for the Rosette, same exposure settings as M31.
Yeah this mirrorless Nikon Z50 is a gem. Just did a little more processing on M31, using StarNet to do some star reduction, it maybe too much for some, but I like it.

Here's a shot of my setup.

Benro Mach3 Tripod
Spare mobile phone using qDslrDashboard (USB tethered), a cheapo cycle mount to attach it to the tripod.
COOWOO lens warmer
2 USB power banks (1 to power the star tracker, 1 for the lens warmer)

Thank you for sharing your settings, it's interesting you didn't take any darks, that'll bring the taking time of the calibration frames down , I may experiment with this. I often use starnett ++ when processing DSOs as you can alter the nebulosity and dust lanes much easier. Your images aspire me for when my SA will arrive using my dslr and tamron 70-300mm lens. I love your images and your set up in the previous photographs is very portable which is what I'm looking at, so I can walk to dome dark sites around here and a couple of miles to the cliffs for wide field imaging. Hopefully when my evostar 72ed is delivered I can get some nice images. Keep up the good work, clear skies 👍

You're welcome and thank you.
It seems that darks and bias frames are only more necessary when you really pump up the ISO and for dedicated astro cameras taking 3+min exposures. Flats are an absolutely must have.
My Nikon Z50 has limited battery life and I've found that not taking darks has made little difference, if any. Plus there are no Z50 spare batteries in stock anywhere at the moment, and they're £50-60 a pop.
I've only just purchased a car, after 6 years without one, to enable me to travel to darker areas. I used to lug this kit around on my electric bicycle, but that can only get you so far. Now I can sit in the car watching YouTube vids while I wait :)

I've been trialing Pixinsight, and it looks like I will be purchasing it soon, it's definitely making a difference. Then next on my list is probably the William Optics Zenithstar 61, unless I see something else. Good bye, money.

I'm definitely going to try this next time as my max iso on my Canon 450d is 1600 so a good experiment by just taking flats along with the lights, I do take darks normally, bias as well as these are only quick as flats. Thanks again. Astrophotography the hobby that just keeps taking 😉, the slippery slope ensues for both of us.

      Hello
      No extraordinary images for this lunation, because of the turbulence and the use of infrared filters.
      Here are some images of the 24th, I am working on those of the 25th which will be of the same style.
      Clear skies.

      Just a quick enquiry ... was strolling the lunar surface on Iroc and bumped into this area of florescence on the lunar surface.


      Any thoughts anyone? (Co-ordinates at bottom of screenshot if you want to get better definition from original website).
      Was struggling to see clear heavy impact crater that would account for the wide spread of surface debris?
      Didn't think it was image flare - not expert on that so could be wrong - but noticed on RHS there appears to be traces of surface debris scatter?
      It almost seems like someone threw a very low velocity ‘flour bomb’ at the surface of the Moon?🤨
      Have there been mineral studies done on these areas of exceptional lunar florescence? ... I tapped the phrase into SGL’s Search ... but surprisingly it came up with ‘no results’??
