Comet C/2021 A1 (Leonard) 27/12/2021 Mount: Skywatcher EQ6-R Pro Telescope: Orion 10" f/3.9 Newtonian Astrograph Camera: Nikon D600 (stock) Total exposure: 20 minutes Subs : 15sec x 80 ISO: 400 Filter: Optolong UV/IR cut Corrector: Baader MPCC Mark III Coma Corrector Stacking: Deep Sky Stacker (Comet stacking mode) Processing: Pixinsight Location: Kaburugamuwa, Sri Lanka Thank you.

please check here. you will need all the details for them. http://www.astronomyforum.net/astrophotography-forum/197165-few-stuff-taken-my-kit-lens.html http://www.astronomyforum.net/astrophotography-forum/197850-m8-m20-sigma-50-500mm-lens.html http://www.astronomyforum.net/astrophotography-forum/156345-eta-carina-nebula-ngc3372-widefield.html

thanks. no its not. all images are less than 1 hour of data. between 5min and 45min. subs are between 8sec and 30sec. i can search my data and give exact details if you want.

all of these except for the last one taken with a nexstar GT mount bought from ebay for 70$. most of these are few years old. now i have a good setup but this is how i started and fell in love with this hobby. 55-300mm lens + D5100, eta carinae 55-300mm lens + D5100, lagoon+trifid 50-500mm tamron + D5100, lagoon 50-500mm tamron + D5100, omega centauri 6" newtonian + D5100, orion 55-300mm + D5100, rosette 55-300mm + D5100 50-500mm + D5100, trifid 55-300mm + D5100, orion tripod, D5300, 50mm prime, southern sky

cheap 58mm uv/it cut filter for my 55-300mm nikkor lens so i can use it with my astro modded (full spectrum mod) DSLR.

thank you for checking it again. my setup was bit imaging side heavy when checking it. i may try this tutorial on DEC to reduce some backlash, its for EQ6 but heard that its almost the same for EQ6-R as well http://www.astro-baby.com/EQ6 rebuild guide/EQ6 worm alignment.htm anyone tried this or similar method?

ok thanks. PHD logs don't have GA results i think. my payload is 18kg/40lb ( 10" Newtonian and accessories), i have tested things for two nights and it seems to guide well. I'm getting 0.6"-0.7" total RMS without doing anything extra like PPEC/tuning and can get 15min subs with perfect round stars so ill just leave this as it is for now.

anyone?

Is this declination backlash is normal or not? It was 25,000+ms on AVX so i know that its way better than AVX.

i have few other questions too if you guys don't mind. 1) home position marker. i was using an AVX and it had those marks for dec and RA clearly but EQ6-R pro don't have them in both sides. i know this is not very important but its usable when aligning the mount. is there a way to add marks accurately than using a rough position? 2) when aligning the mount and when we need to select a certain 2nd or 3rd star, we need to use bottom arrow keys to get it and most of the time its displaying "searching.." and its time consuming. sometimes its showing that for 10-15sec. is this normal? I have some trees and buildings covering my view so need to select stars to align.

looks like a common issue ? mine is completely off so the bubble level is not usable. I'm using the mount without extending legs so that's giving a normal level in a flat surface. I'm using a bubble level app in phone when I'm not sure about the surface.

Hi guys i have recently bought the mount, its inbuilt bubble level readings are wrong. anyone have this issue? anyway to calibrate it?
