Hi everyone,  I'm still very new to the Astrophotography world, I've got this pattern on my pics, and have no idea what causes it, and more importantly how to get rid of it? I'm guessing I've done something wrong lol. If anyone can help, could you please give me step by step instructions.  Thankyou. Pete.

I have checked and my darks are 1440 x 810, where as all the others are 1440 x 1080, is there a way to make them all the same size? Thank you. Pete.

Hi I'm very new to astronomy and finally got out last night and took some pics, using my zwoasi662 camera, skywatcher explorer 150pds zwo focuser. I'm trying to begin processing I've managed to load, my lights, dark flats, bias/offset, darks, into Deepsky stacker. I've checked the frames, but I get an error message,  saying. The checked pictures are not compatible: Height mismatch. I'm very new to this, but what have I done wrong? It won't go any further. Any help would be gratefully received, thank you. Pete.

Hi I'm planning on purchasing a dew heater but am unsure about what actual size I need to get. I have a Skywatcher explorer 150pds. I'm quite new to this so appologises. Do I have a 6" or 7 inch scope? Thanks for any help that anyone may offer.

This is my try at jupiter but this is after my attempt at stacking, any advice or constructive criticism would be grateful received. Just be kind as very new to astronomy. I'm using a skywatcher explorer eq5 150pds and zwoasi 662mc camera. Thankyou. Pete.image.bmp

Approximately £20 to £35 per eyepiece. 

Hi I'm new to this, so please accept my apologies. I've very recently purchased a new Skywatcher explorer 150pds and it came with a 28mm eye piece, could I please ask for some advice to what other eye pieces that would be wise to have? Thanks Pete.
