I'm a relative noob, too!
I'm sure people with experience of your scope will be along soon with more advice.
Planets! Don't forget Jupiter and Saturn are around late. My view to the South is limited, but if you have a good view in that direction take a look. They will be low, but will be the 2 brightest objects.

That's not to scale! And I doubt you will be able to see the Whirlpool under current skies. Where in belgium are you (latitude) and do you know what your 'Bortle' scale number is? This is a scale showing light pollution. You can find it here: https://clearoutside.com/ just enter your location.
Don't worry, I think you have just over-estimated what you will see on your first night. I have an 8" dob and I know I won't see M51 just now (even if there were no clouds!) I saw it about 5 weeks ago and even then it was not obvious.
Go for some star clusters or bright planetary nebulas. M13 (the Hercules cluster) or M57 (the Ring Nebula) should be visible still. In a few months, things will be getting properly dark again.

The skies are very light just now, and deep-sky-objects will be hard to see. What is it you think you were looking at? Have you been using a star-map or stargazing app of some kind?
As for the reversed-image you see through the scope - you will soon get very used to it. Don't worry.

Shouldn't you be outside, stargazing?

Point the tube at a bright surface, take out the eyepiece and have a look down the focuser. Take a picture of what you can see, if you can.

I really like the spirit level attached
That's a Belgian spirit level?

The 1.25"-2" Clicklock won't help as it is clamp "A" that is the problem. As the Clicklock has an undercut, "A" will tilt it and being tilted is worse than a slight offset.
I see. So 2 ClickLocks then! That will increase the focuser height quite a bit!

I was looking to replace the adapter (B) with a clicklock mainly for centering issues. The Revelation looks ok for that too.
I wasn't aware of the EP weight limit for the 2" holder (A)! Is that what Bresser specify? I've no 2" EPs yet.

Hi,
In the pic below, I've got the Bresser 2" EP clamp ('A') and the 2"-1.25" adapter ('B')
Stardaze - 'A' is what you would replace with the Baader ClickLock for hexafoc? You would still require the converter 'B', which is what is threaded for a 2" filter (arrowed)
If you replace B with: https://www.firstlightoptics.com/adapters/baader-clicklock-2-125-adapter-2956214.html, this actually has the 2" filter thread. So the 2" filter is attached to either the adapter for the 1.25" EPs, or the actual 2" EPs.
Have I understood correctly?

And why many change it for a right angle erect image finder. ( RACI )🙂
Which then leads to a Telrad to get you in the right location to start with. Then before you know it, you are looking at counterweights to keep the scope balanced....

Hi,
Is this thread worth being made into a 'sticky'? It' got sooo much useful information, I'm using a shortcut to it for future reference.

I'm at sea-level (about 100m from the beach). No issues yet, this year, but have been thinking about getting prepared for the dew.
I'm unclear about using dew bands/heaters with a dob. I thought we were busy trying to get everything at a stable equilibrium temperature-wise, rather than having anything that might create convection currents? I understand how a dew shield would keep the moisture away from the mirrors, and how we can use heating devices on EPs and finders. But surely we don't want to start heating up parts of the OTA?

It's reasonably mirrored, but I'm not sure it's of much use though? What are you thinking?
There was a post recently where a replacement mirror had a 'mirrored' rear surface. The recipient was a little concerned and cue much musings on what had happened.
Here it is:

FLO, please let me know if you want me to place this on a separate thread, but here is my first look and comparison to the H130p video:
HI Chris,
In your video, the rear of the primary mirror looks mirrored, rather than frosted. Can you confirm?

I've just used some white electrical tape on the outside and flocking the inside has covered the holes on the inside.
That will get my OCD going! Although the internal flocking sounds like a good idea. Can one get small amounts, otherwise I'll be on the 'wanted' page?

Hi,
I've recently bought a new finder to replace the plasticky little one that came with the Bresser 8" dob. The recommended shoe is the Baader universal, which I have too,
The Baader has 3 screw holes. The shoe I have removed have 4 in a square layout. I can either use two width-ways, or just a single one, and use the middle hole in the Baader. I prefer the latter, because it means I can shift the shoe across slightly, and leave room for the new Telrad. The Telrad also then covers 2 of the remaining open holes. See pictures below. Otherwise, the Telrad won't fit in the gap left between the Baader shoe and the focuser.
So I have 2 options: stick with what you see in the picture, or use 2 screws to hold the new shoe and replace the Telrad with a Rigel Quikfinder.
Either way, I need to fill in the remaining open 6mm hole(s). Also, the screws and nuts that were fixing the old shoe are too narrow/long for the Baader - I don't fancy them sticking over 12mm into the tube, especially as the screws are shiny silver. The nuts are black though, but M4, whereas the Baader really needs M5.
So eventually got to the point of the post. Advice, please:
1) I can get the correct M5 bolts in various configurations, but can't find any black M5 nuts available in small volumes. Any anyone suggest a suitable source for black M5 nuts? Otherwise I'll be painting them in place - and I don't fancy that.
2) Has anyone had any luck using grommets or blanking plugs to close these holes? Or should I be looking at very short bolts?
Thanks.

Hi AA&D,
Unless you are going to have issues carrying the larger scope, I'd go for the 200. Otherwise you will always be thinking "I'd have seen more/better/clearer" when looking at something through the 150.

Did you report it to eBay?

There's another thread about this scope. You could ask to see if anyone else is seeing this issue?

Exactly that 👍
Is that little dovetail moulded into the main part, or bolted on?

Can you get a pic of the mounting plate / shoe on the scope?

Looking good! Wish my secondary was that spot-on to start with!

Ok, an update and last night was the first night it was a semi clear sky. So sat our with binoculars and sun lounger and finally managed to locate Hercules keystone lol. I know I know I am a little slow at this 🙂 But now I am understand more of the sky it was easier.... I located Arcturus high up in the sky to the right. Vega to the left and scanned a third to the right from Vega and there it was... simples when you see it. Also located corona. The best thing so far is the constellation within Vega.... so clear in binoculars and with the double double star. My next task once I am up to speed with scope is to spend time finding the ring nebula (M57) south of vega 🙂 Pocket sky atlas is brilliant for this!
The M13 and M57 were the first things I observed when I got my new scope. The Ring nebula is great - it looks so incongruous when seen in a scope (IMHO).

Let's talk filters

Yes - but how far from full extension do you need to get focus? You'd only need to reach the extension required by the EP that has the shortest focal depth?
