Hi

I wanted to add more data to this one before calling it done, but I think our recent weather won't let me add anything else for the foreseeable future..

Anyhow.. attached is an image of NGC2835 at 30% of full size, but full frame and heavily compressed; better one here:

A 50% full size version is available for download at the link above.

5hrs of total exposure with a GSO RC14 @ f/8 + ASI2600MC OSC camera + EQ8. Processed with APP.
Data taken from suburban Melbourne

Thanks Maurice, have added this beautiful galaxy to my list.

Well sought out and well done!

Nice to see a new galaxy being imaged.

It looks to be a faint one. Nicely done.

Great capture of this rarely presented tiny faint Galaxy
Nicely processed too
Well done !!
How’s the backlash on your EQ8 as I have a new EQ8-R pro arriving in June ( so far most folk say it’s pretty tame and doesn’t cause to much of an issue. I’m assuming you have the older version ? )
Thanks

Thanks Peter. It is a beaut galaxy, albeit quite faint from the 'burbs.



Thank you Greg.



Thanks Martin.

The EQ8 has been a very good mount for me.
Backlash is significant in my example on the DEC axis & virtually non existent in RA.
Its manageable though with a slight imbalance in DEC.

I do have the older version; in fact I think it came out with the first shipment of these mounts when they were released.

I use an OAG when imaging & with an ASI290 guidecam I'm sampling at about 0.2"/pixel on my RC14. So far it has behaved very well. Attached is a guide graph from last night, Typically, on nights of average seeing, I get about 0.3-0.5" RMS guiding.

Thanks Maurice
Appreciate the reply and guide graph
Your guiding numbers align with pretty much what most folk achieve straight out of the box with both the EQ8 and EQ8-R
My existing EQ6-R carrying 15kg use to guide around 0.70 to 0.80 on most nights over the past 3 years, then a couple of months ago I re orientated my Newt with camera facing down , adjusted both worm gears and adjusted drive belts to minimise backlash , re balanced and it now guides between 0.60 to 0.70
If my new EQ8-R guides 0.50 or lower out of the box then I’ll be stoked as I know I could spend some time to improve it. It will be carrying a 10” f5 CF newt , so just less than 20kg.
Only another 3 months to wait for it ......

Cheers
Martin
