My advice is be patient , save your pennies and buy a cooled camera if your serious about getting into long exposure deep sky imaging. Thermal noise or dark current from cameras has a detrimental effect on SNR and can only be mitigated with cooling
Yes you can use the 585MC ( Planetary camera ) if your nights are below 16C all year round ( and even then pushing 3 or 5 min subs will have significant noise) or you just want to do lucky imaging ( short exposures of 10 to 30 sec ) or EAA. I call this scenario “restricted” long exposure Astrophotography.Cameras are designed and used for specific purposes, the 585MC is a planetary camera not a bonafide deep sky camera for long exposure AP
I used a DSLR in my Newts for 3 years and struggled with so much noise , mainly thermal noise with those longer subs ( 2 min and above ) Updated to the 2600MC and it opened up a whole new world in Astrophotography, chalk and cheese
Go cooled you will not regret it
Hopefully other folk offer similar advice
Good luck !!
Cheers
