Hi William, Thank you for the links and detailed information, I’ll remove the rings, measure and order them. thank you once again

Hello everyone, Can someone advice where I can purchase O rings for Lunt LS60, and how many rings are needed to be replaced? Thanks in advance,

Hello, I wondered if someone could advice or suggest if there is a hand controller that is available that could connect to a stepper motor. I use to have the controller box that attached to the motor and laptop, all I'm left with is the motor, and would like to connect it to my solar scope (I have the necessary attachments). Thanks in advance.

Hi Andrew and all who have contributed to this thread. This has been a great read especially when I have been mulling over a dedicated DSO camera and to be honest I'm more or less inclined towards getting a mono camera (been DSLR imaging over last few months). The one question I'm mulling over is, do I need light pollution filter? Narrowband will happily cut through light pollution. I've been quite happy with L-Extreme and for broadband IDAS light pollution filter (2") has worked well with DSLR. I was wondering, what do folks do for LRGB and light pollution especially for Luminance, do you replace the L filter with light pollution filter e.g Baader Neodymium or IDAS Filter? Or do you simply use software to remove any effect of light pollution from Luminance data? Would appreciate feedback from Users of Mono Camera. Thanks in advance, Nihal. ps: I'm in Bortle 5 as per Clear Outside

Great, Thanks Waldemar. I can save a few pennies by getting 1.25" filter.

Might seem obvious but I rather ask the stupid questions... If use 2 filters Session 1) 2" IDAS LP filter for broadband Session 2) 1.25" L-enhance filter or L-extreme filter And decide to combine both session, would that work i.e. using different filter sizes? or Would both filters need to be 2" or 1.25"? Thanks in advance.

Hi, I use Lynx Astro FTDI EQDIR USB Adapter for Sky-Watcher Mount to connect EQ5 pro mount to ASIAIR pro. Simply connect the mount (hand controller connector) and ASIAIR (USB 2) with the EQDIR cable. Power up ASIAIR pro and select “EQ Mod Mount”, once selected make sure the switch next to the mount name is toggled on (green) to connect the mount. Use the manual buttons to slew test if mount is responding to ASIAIR. I don’t use the hand controller.

I got my camera delivered earlier this week and had sticker... “may contain snow”... forecast was for snow made me smile 😀

Great Christmas gift, bought 4 from FLO.

Any news or update on Zwo shipments, I’m waiting on camera and filter drawer... anticipation not bothering me, honest (acting all cool). Nihal.

Hi vlaiv, This is brilliant, thanks for the step by step guide, this is very helpful. I'm sure will be helpful for lot of people here. 👍

Hi Ivor, Thank you for looking at M33, I'm must say all you guys are wonderful and very helpful. One generally gets to see end results and doesn't know what the initial data looks like...I was in despair before I started this topic but now I can't wait to get my hands on some of the softwares (at least Gimp is free) also can't wait to get out again. I did use the Bahtinov mask to focus before PA, guiding with this was not particularly the best and dithering was refusing to settle (I still need to find my way with the parameters in ASIAIR pro) and was a bit breezy too, I'm sure that would affect the subs. There are some circular artefacts, which don't appear on the unprocessed tif file (they are quite well defined circles), I reckon this could be eliminated using flats? Could it be dew? To get more detail in M33 = more subs? Still waiting for trial license for pixinsight, been more than 24hrs, got the initial email still waiting for verification. Looks like I'm going to do my bit during the lockdown by going through the tutorials 😃

Thanks Dave, Does the process change a lot between DSLR and OSC e.g. ZWO cameras?

Hi Vlaiv, That would be very much appreciated, I still don't have PS or Pixinsight installed (trial). And I'm sure it would be helpful and beneficial to other beginners like me. I didn't take flats as I disturbed the focus on the first night while tearing down the equipment, then did the exact same thing on the second night. ps: like how to you the background rather dark, excellent.

Hi Dave, That is rather impressive, I'm glad/pleased and reassured that I'm heading in the right direction. I reckon lots for me to learn in terms of image processing, do you have predefined scripts in pixinsight that run through the stacked image? I found this earlier https://www.lightvortexastronomy.com/tutorial-pre-processing-calibrating-and-stacking-images-in-pixinsight.html Do you think its a good tutorial for beginner? any recommendations? Thank you for the processing, trust me its very reassuring. Earlier I mentioned that Polar Alignment and Guiding needed some work.. PA - Total error as reported by ASIAIR app was 27", I read somewhere or saw in a video that about 10" for a set like mine (WO Red cat 51 f4.9) should suffice. Having said that, the tripod that comes with Explorer scientific iEXOS 100 is rubbish for many reasons, now I've got the mount on EQ5 triop and its rock solid, heavier to carry to the location (car to open space) from where I image but will pay dividends. Guiding Total RMS error was around 2.5", with dithering it was all over the place. I've read sub 1" is good M31 was with dithering M33 dithering switched off as it would complain about settle time. Lastly if you don't mind me asking, which bits are done in Pixinsight and PS
