Having bought a Baader steel track focuser from the widescreen centre I wanted a 2” M48 adapter but at the time of purchase was out of stock as were all other Astro retailers, but once they had one in stock they emailed me to see if I still wanted one and had put one by for me , despite being a Sunday I replied and had a reply soon after and put in an order which was swiftly delivered , would recommend as for service can’t fault them , emails were quickly replied too , only fault I could say is delivery options for smaller items are expensive and an option for Po 1st class delivery would be helpful.

Better fitting an autofocuser , I use via Apt works a treat using autofocus aid in Apt now works with dslr cameras though I use a zwo533mc.

New target for me 3hrs , l-Extreme filter , tecnosky ,70AG Refractor , No darks flats and bias .

Yes you will have too , same camera different sensor no two will be exactly the same hot pixels etc , I use darks on my zwo533mc.

Thanks yes mine is rggb i will have a look again I thought there was boxes that needed setting up rather than simply choosing rggb which I didn’t see .

Does anyone know or tell me what the debayer settings are I would need to input into nebulosity for a zwo533mc , I have been playing about trying to stack a set of images but no idea 🤷🏻‍♂️ what parameters to input . regards Dave

One thing to be aware before purchasing a L-Extreme filter you get large halos on bright stars such as Altinak so pick targets wisely as I understand it is caused by the o3 channel or wait until manufacturers have solved the problem.

Using Apt and focussing using inv power it’s constantly checking focus value and adjusts to suit so haven’t bothered fitting the temp sensor on my Deepskydad auto focuser.

Did you know you can get anti reflective glass https://www.wessexpictures.com/cgi-bin/showpage.fcgi

Can someone confirm the body diameter of the zwo533mc please.

I used the foam that the steeltrack came with in box and cut a small strip , a silly design error , there is also a solution here not sure if they have a 150pds one https://en.rbfocus.net/product-page/adaptador-200pds-para-enfocador-baader-diamond-steeltrack

I have the zwo533mc and it’s a game changer 👍

That’s a lovely image well done 👍

I don’t worry too much about the halos , clear skies is my biggest problem lols 😆 I must try taking without the l extreme and using startools Narrow band accent feature to add the NB data to the wide band data just to see if that helps just need another clear night .

Rosette Nebula 3.8hrs zwo533mc darks flats and flat darks , LExtreme filter processing in Startools stacking in Astap the darker version was after my lad tweaked on his iPhone to his perception of what deep space looks like,

I have only just started looking at creating a mosaic in Apt and Just found this video on creating a mosaic using Apt I couldn’t see a guide on here so thought I’d post if it helps someone ,now you need Cart du ciel to produce the coordinates but once saved in custom objects in Apt then you could switch to stellarium if you so wish ,i dont think stellarium has this feature yet but cdc does and apt lets you import coordinates ,so worthy of sharing and the simlest way i have found so far for APT, now I’m assuming once you align your sensor to the grid lines in cdc (see video)you could mark your focuser so less faffing about or maybe you have another tip for aligning your sensor then add your thoughts.

@peter shah may be good for advice.

Try skytrack I think it’s £10 there’s a video to configure to Stellarium I will find it and add to post here we are , not used but I did configure to Stellarium not sure about alt /ax type mount . regards Dave

Picked up a nice guidescope from a very nice man today @SyedT 👍

Lol no that was my brummie screwdriver

+1 for the concentre initially I wasn’t too sure until I found my focuser not 90degrees to OTA , I’m impressed now 👍.

Aperture mask from Deepskydad for my 200pds , fits a treat

Had a play in startools

Dithering does not take long and benefits outweigh lost time , you can dither every other sub ,

More data will definetley help nearer 4 hrs will help noise ,also if you can dither between frames will help with walking noise ,if posting the tif best post the file straight from DSS no editing done
